-These are the rules so that older bsd systems and the POSIX standard
-system can coexist togather.
-
-  1) If you use select then include "ntp_select.h"
-     select is not standard, since it is very system depenedent as to where
-     select is defined.  The logic to include the right system dependent
-     include file is in "ntp_select.h".
-  2) Always use POSIX defintion of strings.  Inlcude "ntp_string.h" instaed
-     of <string.h>.
-  3) Always include "ntp_malloc.h" if you use malloc.
-  4) Always include "ntp_io.h" instead of <sys/file.h> or <fnctl.h> to
-     get O_* flags.
-  5) Always include "ntp_if.h" instead of <net/if.h>.
-  6) Always include "ntp_stdlib.h" instead of <stdlib.h>.
-  7) Always define a system identifier for any new system added to the
-     machines directory.  The identifier should always start with SYS_!
-  8) Define any special defines needed for a system in
-     ./include/ntp_machine.h based on system identifier. This file is
-     included by the "ntp_types.h" file and should always be placed
-     first after the <> defines.
-  9) Define any special library prototypes left over from the system
-     library and include files in the "l_stdlib.h" file. This file is
-     included by the "ntp_stdlib.h" file and should ordinarily be
-     placed last in the includes list.
- 10) Don't define a include file by the same name as a system include file.
-     
-  
-"l_stdlib.h" can contain any extra definitions that are needed so that 
-gcc will shut up.  They should be controlled by a system identifier and 
-there should be a seperate section for each system. Really this will
-make it easier to maintain. 
-
-See include/ntp_machines.h for the verious compile time options.
-
-Good luck.

-The xntp3 Distribution
-
-This directory and its subdirectories contain the Network Time Protocol
-Version 3 (NTP) distribution for Unix systems. It contains source code
-for the daemon, together with related auxiliary programs, documentation
-and strange stuff. You are welcome to the lot, with due consideration of
-the COPYRIGHT files stashed in the distributions. You are also invited
-to contribute bugfixes and drivers for new and exotic radios, telephones
-and sundials. This distribution is normally available by anonymous ftp
-as the compressed tar archive xntp-<version>.tar.Z in the pub/ntp directory
-on louie.udel.edu.
-
-The base directory contains the distributions and related stuff. The files
-marked with a "*" are not distributed, but generated. Most of
-the subdirectories contain README files describing their contents. The
-base directory ./ includes:
-
-COPYRIGHT       file specifying copyright conditions, together with a
-                list of major authors and electric addresses.
-
-Config          * configuration file built by the configuration script
-                "make makeconfig" and used to build the makefiles in the
-                various subdirectories. Do not edit.
-
-Config.local    * Unless you have a reference clock (besides the local
-		computer clock) or want to change the default installation
-		directory (/usr/local/bin) not action is needed. For
-		configuring a reference clock a "make refconf" should
-		suffice. Diehards can still use an editor on this file.

-This version of NTP was converted to the BSD-style Makefile system by
-Garrett Wollman (wollman@FreeBSD.org); it is based on version
-3.4e (beta) from the University of Delaware.
-
-Besides the Makefile changes, the DES code has been completely removed
-in order to make this code exportable.  If you have a legal copy of
-`authdes.c', you can just add it to the lib/ directory and add `-DDES'
-to the AUTHDEFS in Makefile.inc.
-
-You can change CLOCKDEFS in the same file to add other reference clocks.
-
-This port should work under either FreeBSD 1.1 or FreeBSD 2.0.  For
-1.1, change the `-DSYS_44BSD' in Makefile.inc to `-DSYS_386BSD'.

-For special hints on setup/compilation/installation and other general
-topics you may persue the files in the hints directory.
-
-This file contains the usual instructions to compile and install the programs in
-this distribution. To make these programs:
-
-(0) Make sure that you have all necessary tools for building executables.
-    These tools include cc/gcc, make, awk, sed, tr, sh, grep, egrep and
-    a few others. Not all of these tools exist in the standard distribution
-    of todays UNIX versions (compilers are likely to be an extra product).
-    For a successful build all of these tools should be accessible via the
-    current path.
-
-(1) By default, if there is no Config.local, the system will generate one
-    to support a local ref clock (i.e. run off the system clock).
-    Greenhorns can skip on to (2).
-    
-    HACKers can create a Config.local and choose the compilation options,
-    install destination directory and clock drivers.
-    A template for Config.local can be found in Config.local.dist.
-    There are two Configurations that can be auto-generated:
-	make Config.local.local		# network configuration plus local
-					# reference clock (the default)
-	make Config.local.NO.clock	# network only configuration
-
-    To set up for a radio clock, type "make refconf" and answer the questions
-    about PLL, PPS and radio clock type.
-    If this is the first use of the ref clock, don't forget to make suitable
-    files in /dev/.
-
-    For custom tailored configuration copying Config.local.dist to Config.local
-    and editing Config.local to suit the local needs is neccessary (at most
-    3 lines to change), or use one of the make's above and then tweak it.
-    Config.local can also be used to override common settings from the
-    machines/* files like the AUTHDEFS= to select very specific configurations.
-    Please use this feature with care and don't be disappointed if it doesn't
-    work the way you expect.
-
-(2) Type "make" to compile everything of general interest. Expect few or
-    no warnings using cc and a moderate level of warnings using gcc.
-    Note: On some Unix platforms the use of gcc can result in quite a few
-          complaints about system header files and type problems within xntp
-          code. This is usually the case when the OS header files are not up
-          up to ANSI standards or GCCISMs. (There may, however, be still some
-	  inconsistencies in the code)
-
-	  Other known problems stem from bugs/features/... in utility programs
-	  of some vendors.
-
-	  See section "build problems" for known problems and possible work-
-	  arounds.
-
-    Each time you change the configuration a script that pokes your hard- and
-    software will be run to build the actual configuration files.
-    If the script fails, it will give you a list of machines it knows about.
-    You can override the automatic choice by cd to the ../machines directory
-    and typing "make makeconfig OS=<machine>", where <machine> is one of the
-    file names in the ../machine directory.
-
-    The shell script will attempt to find the gcc compiler and, if
-    found, will use it instead of the cc compiler.  You can override
-    this automatic choice by cd to the ../machines directory and typing
-    "make makeconfig COMP=<compiler>", where <compiler> is one of the file
-    names in the ../compilers directory. This can be combined with
-    the OS argument above.
-
-    The configuration step can be separatly invoked by "make makeconfig".
-
-    Note that any reconfiguration will result in cleaning the old
-    program and object files.
-
-(3) Assuming you have write permission on the install destination directory,
-    type "make install" to install the binaries in the destination directory.
-    At the time of writing this includes
-    the programs xntpd (the daemon), xntpdc (an xntpd-dependent query
-    program), ntpq (a standard query program), ntpdate (an rdate
-    replacement for boot time date setting and sloppy time keeping)
-    and xntpres (a program which provides name resolver support for
-    some xntpd configurations).
-
-(4) You are now ready to configure the daemon and start it.  At this
-    point it might be useful to format and print the file doc/notes.me
-    and read a little bit.  The sections on configuration and on the
-    tickadj program will be immediately useful.
-
-Additional "make" target you might find useful are:
-
-clean		cleans out object files, programs and temporary files
-
-dist		makes a new distribution file (also cleans current binaries)
-		All usual scratch and backup files (*.rej, *.orig, *.o, *~
-		core, lint*.errs, executables, tags, Makefile.bak, make.log)
-		will be removed. The distribution is created in a tar file
-		(file name: <prefix><version>.tar.<compression suffix> - with
-		the prefix usually being ../xntp- and a compression suffix
-		of .Z (compress))
-		Note: the file Config.local will never be included in the
-		distribution tar file. For configuration hints to propagate
-		in in distribution changes must be made to Config.local.dist.
-
-depend		possible maker of hazardous waste
-
-refconf		a target to interactively configure reference clock support.
-		This should work for you, but has not yet been tested on
-		the more exotic Unix ports (mostly the supercomputer ones).
-
-Bug reports of a general nature can be sent to David Mills (mills@udel.edu).
-Reports concerning specific hardware or software systems mentioned in the
-COPYRIGHT file should be sent to the author, with copy to David Mills for
-archive.
-
-The distribution has been compiled and run on at least the following
-machines, operating systems and compilers. In all known cases, if
-the gcc compiler eats it with some success, the cc compiler also enjoys
-the meal. The converse is not always true. See the conf directory for
-test suites known to compile with various radio clocks; however, not all
-the combinations that compile have been tested.

-Build Problems (and workaround):
-
-During testing/porting we have found some
-of "make" and "sh" and "awk" features in different implementations.
-If you have problems other tha the one listed below please check for
-usualy things like the latest sh compatible pd shell in your own
-environment. Things like this are known to hinder compilation if
-they are not fully compatible with sh or are buggy.
-
-Current build problem on (Mac) NetBSD, possibly BSDI and 386BSD:
-	pmake (e. g. NetBSD on MAC, possible other BNR2+pmake systems)
-		Following Makefile construction fails for no
-		apparent reason (at least to me)
-		doit:
-			$(MAKE) MAKE=\"$(MAKE)\" all
-
-		all:
-			@echo all done.
-
-		for the "make MAKE=make" call but not for "make" or
-		"make -e MAKE=make". Use the last form if you suffer
-		from that kind of make problems. (Easily detected
-		by failure to build with the message:
-		"don't know how to make make".
-
-		On BSD/386 the solution is to get GNU make and run build as:
-			% gnumake MAKE=gnumake
-		Note that BSD/386 1.0's "sed" goes into an infinite loop if
-		you try to make the "refconf" target -- so edit Config.local
-		by hand if you have a reference clock.  (BSD/386 1.1 will fix
-		this "sed" bug.)
-
-		The NetBSD people claim that this problem goes away
-		when you compile make with POSIX compilation options.
-
-The known sh and some make pecularities have already been taken care of.
-
-Usually the vendor should fix these bugs in vital utilities.
-We try to circumvent these bugs in a hopefully portable way.
-If you can reproduce these bugs on your system please bug your
-vendor/developer group to fix them. We are not trying anything fancy
-in here (except for starting sub-makes) and we are shocked that even
-the most common tools fail so miserably. By the time you get this 
-code the above utilities may already have been fixed. Hopefully one 
-day we do not have to cope with this kind of broken utilities.

-README file for directory ./clockstuff of the NTP Version 3 distribution
-
-This directory contains the sources for utility programs designed to
-support radio clocks. The chutest.c and clktest.c are desgined to
-test the chu_clk and tty_clk line disciplines and STREAMS modules in
-the ../kernel directory.
-
-These files have been modified to work with either the line disciplines
-or the STREAMS modules. Be sure to define -DSTREAM if appropriate.
-
-These are random bits of things written to help with clocks.  You can
-make things in here by typing one or more of:
-
-	make propdelay (or `make')
-	make chutest
-	make clktest
-
-Propdelay computes high frequency propagation delays, given the
-longitude and latitude of the transmitter and receiver.  Use
-this for WWV/H and CHU.  Don't use it for WWVB (the computation
-is easier for that).
-
-Chutest can be used to input and process data from a CHU modem
-attached to a serial port.  It will use the CHU line discipline
-(if installed), or raw mode otherwise.  This was used to test
-out the initial reduction algorithms, and may not be up to date.
-
-Clktest can be used to test the clock line discipline (CLKLDISC,
-it must be available), and to take a look at radio clocks attached to a
-serial port.

-/*
- * This can be used to get a rough idea of the HF propagation delay
- * between two points (usually between you and the radio station).
- * The usage is
- *
- * propdelay latitudeA longitudeA latitudeB longitudeB
- *
- * where points A and B are the locations in question.  You obviously
- * need to know the latitude and longitude of each of the places.
- * The program expects the latitude to be preceded by an 'n' or 's'
- * and the longitude to be preceded by an 'e' or 'w'.  It understands
- * either decimal degrees or degrees:minutes:seconds.  Thus to compute
- * the delay between the WWVH (21:59:26N, 159:46:00W) and WWV (40:40:49N,
- * 105:02:27W) you could use:
- *
- * propdelay n21:59:26 w159:46 n40:40:49 w105:02:27
- *
- * By default it prints out a summer (F2 average virtual height 350 km) and
- * winter (F2 average virtual height 250 km) number.  The results will be
- * quite approximate but are about as good as you can do with HF time anyway.
- * You might pick a number between the values to use, or use the summer
- * value in the summer and switch to the winter value when the static
- * above 10 MHz starts to drop off in the fall.  You can also use the
- * -h switch if you want to specify your own virtual height.
- *
- * You can also do a
- *
- * propdelay -W n45:17:47 w75:45:22
- *
- * to find the propagation delays to WWV and WWVH (from CHU in this
- * case), a
- *
- * propdelay -C n40:40:49 w105:02:27
- *
- * to find the delays to CHU, and a
- *
- * propdelay -G n52:03:17 w98:34:18
- *
- * to find delays to GOES via each of the three satellites.

-# Definitions for the library:
-#
-# You must define one of -DXNTP_BIG_ENDIAN, -DXNTP_LITTLE_ENDIAN
-#	or -DXNTP_AUTO_ENDIAN depending on which way your machine's
-#	bytes go for the benefit of the DES routine.  Most things
-#	sold by DEC, the NS32x32 and the 80386 deserve a
-#	-DXNTP_LITTLE_ENDIAN.  Most of the rest of the world does
-#	it the other way.  If in doubt, pick one, compile
-#	everything and run authstuff/authcert < authstuff/certdata.
-#	If everything fails, do it the other way.
-#
-#	Under BSD, you may define -DXNTP_NETINET_ENDIAN to use
-#	netinet/in.h to determine which of -DXNTP_BIG_ENDIAN and
-#	XNTP_LITTLE_ENDIAN should be used.
-#
-LIBDEFS= -DWORDS_BIGENDIAN
-
-#
-# Library loading:
-#
-# If you don't want your library ranlib'ed, chose the second line
-#
-RANLIB=		ranlib
-#RANLIB=	: # ar does the work of ranlib under System V
-
-#
-# Definitions for programs:
-# 
-# If your compiler doesn't understand the declaration `signed char',
-#       add -DNO_SIGNED_CHAR_DECL.  Your `char' data type had better be
-#	signed.  If you don't know what the compiler knows, try it
-#	without the flag.  If you get a syntax error on line 13 of
-#	ntp.h, add it.  Note that `signed char' is an ANSIism.  Most
-#	older, pcc-derived compilers will need this flag.
-#
-# If your library already has 's_char' defined, add -DS_CHAR_DEFINED.
-#
-# For SunOS 3.x, add -DSUN_3_3_STINKS (otherwise it will complain
-#	about broadaddr and will hang if you run without a -d flag
-#	on the command line.  I actually can't believe the latter
-#	bug.  If it hangs on your system with the flag defined, peruse
-#	xntpd/ntp_io.c for some rude comments about SunOS 3.5 and try it
-#	the other way).  This flag affects xntpd only.
-#
-# For Ultrix 2.0, add -DULT_2_0_SUCKS.  This OS has the same hanging
-#	bug as SunOS 3.5 (is this an original 4.2 bug?) and in addition
-#	has some strangeness concerning signal masks.  Ultrix 2.3 doesn't
-#	have these problems.  If you're running something in between
-#	you're on your own.  This flag affects xntpd only.
-#
-# For SunOS 4.x, add -DDOSYNCTODR_SUCKS to include the code in ntp_util.c
-#	that sets the battery clock at the same time that it updates
-#	the driftfile. It does this by revving up the niceness, then
-#	sets the time of day to the current time of day. Ordinarily,
-#	you would need this only on non-networked machines.
-#
-# For some machines, settimeofday does not set the sub-second component
-#       of the time correctly. For these machines add -DSETTIMEOFDAY_BROKEN.
-#       If xntpd keeps STEPPING the clock by small amounts, then it is
-#       possible that you are suffering from this problem.
-#
-# There are three ways to pry loose the kernel variables tick and tickadj
-#	needed by ntp_unixclock.c.  One reads kmem and and is enabled
-#	with -DREADKMEM.  One uses Sun's libkvm and is enabled with
-#	-DUSELIBKVM. The last one uses builtin defaults and is enabled
-#	with -DNOKMEM. Therefore, one of -DUSELIBKVM, -DREADKMEM or
-#	-DNOKMEM must be defined. Suns and recent BSD should use
-#	-DUSELIBKVM; others should use -DREADKMEM. If -DUSELIBKVM, use
-#	the DAEMONLIBS below to get the kernel routines.
-#
-# If your gethostbyname() routine isn't based on the DNS resolver (and,
-#	in particular, h_errno doesn't exist) add a -DNODNS.  There
-#	doesn't seem to be a good way to detect this automatically which
-#	works in all cases.  This flag affects xntpres only.
-#
-# Adding -DLOCK_PROCESS to the compilation flags will prevent
-#	xntpd from being swapped out on systems where the plock(3) call
-#	is available.
-#
-# The flag -DDEBUG includes some debugging code.
-#
-# The flag -DREFCLOCK causes the basic reference clock support to be
-#	compiled into the daemon.  If you set this you will also want
-#	to configure the particular clock drivers you want in the
-#	CLOCKDEFS= line below.  This flag affects xntpd only.
-#
-# To change the location of the configuration file, use a
-#	-DCONFIG_FILE=\\"/local/etc/ntp.conf\\" or something similar.
-#
-# Under HP-UX, you must use either -Dhpux70 or -Dhpux80 as,
-#	well as -DNOKMEM
-#
-# If your library doesn't include the vsprintf() routine, define
-#	NEED_VSPRINTF.
-#
-# There are three ways to utilize external 1-pps signals. Define -DPPS to
-#	include just the pps routine, such as used by the DCF77 reference clock
-#	driver. Define -DPPSDEV ito include a serial device driver. This
-#	requires a serial port and either a line discipline or STREAMS module.
-#	Define -DPPSCD to include the driver and a special kernal hack
-#	(for SunOS 4.1.1) that intercepts carrier-detect transitions
-#	generated by the pps signal. Only one of these flags should be defined.

-#	streams module under SunOS 4.2.
-#
-# Define -DCHU to include support for a driver to receive the CHU
-#	timecode.  Note that to compile in CHU support you must
-#	previously have installed the CHU serial line discipline in
-#	the kernel of the machine you are doing the compile on.
-#
-# Define -DDCF to include support for the DCF77 receiver. This code
-#	requires a special STREAMS module found in the kernel directory.
-#	Define -DDCFPPS for PPS support via the DCF77 receiver; also,
-#	devine -DPPS in the DEFS above.
-#
-# Define -DMX4200 to support a Magnavox 4200 GPS receiver. Define -DPPSCD
-#	in the DEFS above for PPS support via this receiver. This requires
-#	the ppsclock streams module under SunOS 4.2.	
-#
-# Define -DAS2201 to include support for the Austron 2201 GPS Timing
-#	Receiver. Define -DPPSCD in the DEFS above for PPS support via this

-# Define -DGOES to support a Kinemetrics TrueTime 468-DC GOES receiver. This

-# Definitions for programs:
-# 
-# If your compiler doesn't understand the declaration `signed char',
-#       add -DNO_SIGNED_CHAR_DECL.  Your `char' data type had better be
-#	signed.  If you don't know what the compiler knows, try it
-#	without the flag.  If you get a syntax error on line 13 of
-#	ntp.h, add it.  Note that `signed char' is an ANSIism.  Most
-#	older, pcc-derived compilers will need this flag.
-#
-# If your library already has 's_char' defined, add -DS_CHAR_DEFINED.
-#
-# For SunOS 3.x, add -DSUN_3_3_STINKS (otherwise it will complain
-#	about broadaddr and will hang if you run without a -d flag
-#	on the command line.  I actually can't believe the latter
-#	bug.  If it hangs on your system with the flag defined, peruse
-#	xntpd/ntp_io.c for some rude comments about SunOS 3.5 and try it
-#	the other way).  This flag affects xntpd only.
-#
-# For Ultrix 2.0, add -DULT_2_0_SUCKS.  This OS has the same hanging
-#	bug as SunOS 3.5 (is this an original 4.2 bug?) and in addition
-#	has some strangeness concerning signal masks.  Ultrix 2.3 doesn't
-#	have these problems.  If you're running something in between
-#	you're on your own.  This flag affects xntpd only.
-#
-# For SunOS 4.x, add -DDOSYNCTODR_SUCKS to include the code in ntp_util.c
-#	that sets the battery clock at the same time that it updates
-#	the driftfile. It does this by revving up the niceness, then
-#	sets the time of day to the current time of day. Ordinarily,
-#	you would need this only on non-networked machines.
-#
-# There are three ways to pry loose the kernel variables tick and tickadj
-#	needed by ntp_unixclock.c.  One reads kmem and and is enabled
-#	with -DREADKMEM.  One uses Sun's libkvm and is enabled with
-#	-DUSELIBKVM. The last one uses builtin defaults and is enabled
-#	with -DNOKMEM. Therefore, one of -DUSELIBKVM, -DREADKMEM or
-#	-DNOKMEM must be defined. Suns and recent BSD should use
-#	-DUSELIBKVM; others should use -DREADKMEM. If -DUSELIBKVM, use
-#	the DAEMONLIBS below to get the kernel routines.
-#
-# If your gethostbyname() routine isn't based on the DNS resolver (and,
-#	in particular, h_errno doesn't exist) add a -DNODNS.  There
-#	doesn't seem to be a good way to detect this automatically which
-#	works in all cases.  This flag affects xntpres only.
-#
-# The flag -DDEBUG includes some debugging code.
-#
-# The flag -DREFCLOCK causes the basic reference clock support to be
-#	compiled into the daemon.  If you set this you will also want
-#	to configure the particular clock drivers you want in the
-#	CLOCKDEFS= line below.  This flag affects xntpd only.
-#
-# To change the location of the configuration file, use a
-#	-DCONFIG_FILE=\\"/local/etc/ntp.conf\\" or something similar.
-#
-# Under HP-UX, you must use either -Dhpux70 or -Dhpux80 as,
-#	well as -DNOKMEM
-#
-# If your library doesn't include the vsprintf() routine, define
-#	NEED_VSPRINTF.
-#
-# Define -DPPS to include support for a 1-pps signal. Define -DPPSDEV
-#	to include a device driver for it. The latter requires a
-#	serial port and either a line discipline or STREAMS module.
-#	The PPS signal may also be generated via a reference clock
-#	module like DCF77. In that case a special define is required for
-#	the reference clock module (only one source of PPS signal should

-# Following defines can be set in the DEFS_OPT= define:
-#
-# The flag -DDEBUG includes some debugging code. To use this, include
-# the define and start the daemon with one or more -d flags, depending
-# on your calibration of pearannoya. The daemon will not detach your

-# volume to bearable levels.
-#
-# To change the location of the configuration file, use a
-# -DCONFIG_FILE=\\"/local/etc/ntp.conf\\" or something similar.
-#
-# The -DSYSLOG_FILE defines allows logging messages that are normally
-# reported via syslof() in a file. The file name can be configured using
-# the configuration line "logfile <filename>" in CONFIG_FILE.
-#
-# There are three serial port system software interfaces, each of
-# which is peculiar to one or more Unix versions. Define
-# -DHAVE_SYSV_TTYS for basic System V compatibility; define -DSTREAM
-# for POSIX compatibility including System V Streams, and
-# HAVE_BSD_TTYS for 4.3bsd compatibility. Only one of these three
-# should be defined. If none are defined, HAVE_BSD_TTYS is assumed.
-# Usually these defines are already set correctly.
-#
-DEFS_OPT=-DDEBUG
-#
-# The DEFS_LOCAL define picks up all flags from DEFS_OPT (do not delete that)
-# and one of the following:
-#
-# The flag -DREFCLOCK causes the basic reference clock support to be
-# compiled into the daemon. If you set this you may also want to
-# configure the particular clock drivers you want in the CLOCKDEFS= line
-# below. This flag affects xntpd only. This define is included by
-# default when using the "make makeconfig" script.
-#
-# The next two sets of defines are meaningful only when radio clock

-# these features, these delicious complexities can be avoided. Ordinarily,
-# the "make makeconfig" script figures out which ones to use, but your
-# mileage may vary.
-#
-#       There are three ways to utilize external 1-pps signals. Define
-#       -DPPS to include just the pps routine, such as used by the DCF77(PARSE)
-#       clock driver. Define -DPPSCLK to include a serial device driver
-#       which avoids much of the jitter due to upper level port

-#       which are in the ./kernel directory. Define -DPPSCD to include a
-#       special driver which intercepts carrier-detect transitions
-#       generated by the pps signal. This requires a nondedicated serial
-#       port and the ppsclock streams module in the ./kernel directory.
-#       Only one of these three flags should be defined.
-#
-# The flag KERNEL_PLL causes code to be compiled for a special feature of
-#	the kernel that (a) implements the phase-lock loop and (b) provides
-#	a user interface to learn time, maximum error and estimated error.
-#	See the file README.kern in the doc directory for further info.
-#	This code is activated only if the relevant kernel features have
-#	been configured; it does not affect operation of unmodified kernels.
-#	To compile it, however, requires a few header files from the

-# Radio clock support definitions (these only make sense if -DREFCLOCK
-# used), which is normally the case. Note that a configuration can include
-# no clocks, more than one type of clock and even multiple clocks of the
-# same type.
-#
-#       For most radio clocks operating with serial ports, accuracy can
-#       be considerably improved through use of the tty_clk line
-#       discipline or tty_clk_STREAMS streams module found in the
-#       ./kernel directory. These gizmos capture a timestamp upon
-#       occurrence of an intercept character and stuff it in the data
-#       stream for the clock driver to munch. To select this mode,
-#       postfix the driver name with the string CLK; that is, WWVB
-#       becomes WWVBCLK. If more than one clock is in use, the CLK
-#       postfix can be used with any or all of them.
-#
-#       Alternatively, for the best accuracy, use the ppsclock streams
-#       module in the ./ppsclock directory to steal the carrier-detect
-#       transition and capture a precision timestamp. At present this
-#       works only with SunOS 4.1.1 or later. To select this mode,
-#       postfix the driver name with the string PPS; that is, AS2201
-#       becomes AS2201PPS. If more than one clock is in use, the PPS
-#       postfix should be used with only one of them. If any PPS
-#       postfix is defined, the -DPPSPPS define should be used on the
-#       DEFS above.
-#
-# Define -DLOCAL_CLOCK for a local pseudo-clock to masquerade as a

-# Define -DLEITCH for a Leitch CSD 5300 Master Clock System Driver for
-# the HP 5061B Cesium Clock. It should work in all systems with a serial
-# port. The driver does not support the CLK mode, but does support the
-# PPS mode.

-# Define -DMSFEESPPS for an EES M201 MSF receiver. It currently only works
-# under SunOS 4.x with the PPSCD (ppsclock) STREAMS module, but the RCS

-#
-# Define -DIRIG for a IRIG-B timecode timecode using the audio codec of

-#		make a Config.local that supports a local clock
-#		(i.e. allow fallback to use of the CPU's own clock)

-#
-#
-# NOTE TO GREENHORNS
-#
-# For plug-'n-play and no radios or other complicated gadgetry,
-# use "make Config.local.green" as above.
-#
-# Following defines can be set in the DEFS_OPT= define:
-#
-# The flag -DDEBUG includes some debugging code. To use this, include
-# the define and start the daemon with one or more -d flags, depending
-# on your calibration of pearannoya. The daemon will not detach your
-# terminal in this case. Judicious use of grep will reduce the speaker
-# volume to bearable levels.
-#
-# To change the location of the configuration file, use a
-# -DCONFIG_FILE=\\"/local/etc/ntp.conf\\" or something similar.
-#
-# The -DSYSLOG_FILE defines allows logging messages that are normally
-# reported via syslof() in a file. The file name can be configured using
-# the configuration line "logfile <filename>" in CONFIG_FILE.
-#
-# There are three serial port system software interfaces, each of
-# which is peculiar to one or more Unix versions. Define
-# -DHAVE_SYSV_TTYS for basic System V compatibility; define -DSTREAM
-# for POSIX compatibility including System V Streams, and
-# HAVE_BSD_TTYS for 4.3bsd compatibility. Only one of these three
-# should be defined. If none are defined, HAVE_BSD_TTYS is assumed.
-# Usually these defines are already set correctly.
-#
-DEFS_OPT=-DDEBUG
-
-#
-# The DEFS_LOCAL define picks up all flags from DEFS_OPT (do not delete that)
-# and one of the following:
-#
-# The flag -DREFCLOCK causes the basic reference clock support to be
-# compiled into the daemon. If you set this you may also want to
-# configure the particular clock drivers you want in the CLOCKDEFS= line
-# below. This flag affects xntpd only. This define is included by
-# default when using the "make makeconfig" script.
-#
-# The next two sets of defines are meaningful only when radio clock
-# drivers or special 1-pps signals are to be used. For systems without
-# these features, these delicious complexities can be avoided. Ordinarily,
-# the "make makeconfig" script figures out which ones to use, but your
-# mileage may vary.
-#
-#       There are three ways to utilize external 1-pps signals. Define
-#       -DPPS to include just the pps routine, such as used by the DCF77(PARSE)
-#       clock driver. Define -DPPSCLK to include a serial device driver
-#       which avoids much of the jitter due to upper level port
-#       processing. This requires a dedicated serial port and either the
-#       tty_clock line discipline or tty_clk_streams module, both of
-#       which are in the ./kernel directory. Define -DPPSCD to include a
-#       special driver which intercepts carrier-detect transitions
-#       generated by the pps signal. This requires a nondedicated serial
-#       port and the ppsclock streams module in the ./kernel directory.
-#       Only one of these three flags should be defined.
-#
-# The flag KERNEL_PLL causes code to be compiled for a special feature of
-#	the kernel that (a) implements the phase-lock loop and (b) provides
-#	a user interface to learn time, maximum error and estimated error.
-#	See the file README.kern in the doc directory for further info.
-#	This code is activated only if the relevant kernel features have
-#	been configured; it does not affect operation of unmodified kernels.
-#	To compile it, however, requires a few header files from the
-#	special distribution.
-#
-# Note: following line must always start with DEFS_LOCAL= $(DEFS_OPT)
-DEFS_LOCAL= $(DEFS_OPT) -DREFCLOCK -DKERNEL_PLL -DMCAST

-#
-# Radio clock support definitions (these only make sense if -DREFCLOCK
-# used), which is normally the case. Note that a configuration can include
-# no clocks, more than one type of clock and even multiple clocks of the
-# same type.
-#
-#       For most radio clocks operating with serial ports, accuracy can
-#       be considerably improved through use of the tty_clk line
-#       discipline or tty_clk_STREAMS streams module found in the
-#       ./kernel directory. These gizmos capture a timestamp upon
-#       occurrence of an intercept character and stuff it in the data
-#       stream for the clock driver to munch. To select this mode,
-#       postfix the driver name with the string CLK; that is, WWVB
-#       becomes WWVBCLK. If more than one clock is in use, the CLK
-#       postfix can be used with any or all of them.
-#
-#       Alternatively, for the best accuracy, use the ppsclock streams
-#       module in the ./ppsclock directory to steal the carrier-detect
-#       transition and capture a precision timestamp. At present this
-#       works only with SunOS 4.1.1 or later. To select this mode,
-#       postfix the driver name with the string PPS; that is, AS2201
-#       becomes AS2201PPS. If more than one clock is in use, the PPS
-#       postfix should be used with only one of them. If any PPS
-#       postfix is defined, the -DPPSPPS define should be used on the
-#       DEFS above.
-#
-# Define -DLOCAL_CLOCK for a local pseudo-clock to masquerade as a
-# reference clock for those subnets without access to the real thing.
-# Works in all systems and requires no hardware support. This is defined
-# by default when using the "make makeconfig" script and greenhorn
-# configuraiton.
-#
-# Define -DPST for a PST/Traconex 1020 WWV/H receiver. The driver
-# supports both the CLK and PPS modes. It should work in all systems
-# with a serial port.
-#
-# Define -DWWVB for a Spectracom 8170 or Netclock/2 WWVB receiver. It
-# should work in all systems with a serial port. The driver supports
-# both the CLK and PPS modes if the requisite kernel support is installed.
-#
-# Define -DCHU for a special CHU receiver using an ordinary shortwave
-# radio. This requires the chu_clk line discipline or chu_clk_STREAMS
-# module in the ./kernel directory. At present, this driver works only
-# on SunOS4.1.x; operation in other systems has not been confirmed.

-#		-DCLOCK_TRIMSV6  for Trimble SV6 GPS receiver

-# Define -DMX4200PPS for a Magnavox 4200 GPS receiver. At present, this
-# driver works only on SunOS4.1.x with CPU serial ports only. The PPS
-# mode is required.
-#
-# Define -DAS2201 for an Austron 2200A or 2201A GPS receiver. It should
-# work in all systems with a serial port. The driver does not support the

-#
-# Define -DGOES for a Kinemetrics/TrueTime 468-DC GOES receiver. This
-# driver is known to work with some other TrueTime products as well,

-#
-# Define -DOMEGA for a Kinemetrics/TrueTime OM-DC OMEGA receiver. It

-# support the CLK mode, but does support the PPS mode.
-#
-# Define -DTPRO for a KSI/Odetics TPRO-S IRIG-B timecode reader. This
-# requires the SunOS interface driver available from KSI. The driver
-# supports neither the CLK nor PPS modes.
-#
-# Define -DLEITCH for a Leitch CSD 5300 Master Clock System Driver for
-# the HP 5061B Cesium Clock. It should work in all systems with a serial
-# port. The driver does not support the CLK mode, but does support the
-# PPS mode.
-#
-# Define -DMSFEESPPS for an EES M201 MSF receiver. It currently only works
-# under SunOS 4.x with the PPSCD (ppsclock) STREAMS module, but the RCS
-# files on cl.cam.ac.uk still has support for CLK and CBREAK modes.

-# Spectracom 8170/Netclock-2 WWVB receiver. This receiver is equipped

-# ppsclock streams module and the carrier detect line of the CHU
-# receiver below (ttyb). The IRIG signal is connected via an attenuator
-# to the audio port (/dev/audio). The propagation delay computed from
-# geographical coordinates is 8.8 ms, while the receiver delay
-# calibrated at the factory is 17.3 ms, for a total delay of 26.1 ms.
-# This is confirmed within 0.1 ms at the 1-pps signal output using a

-             Audio IRIG Receiver for Precision Timekeeping
-
-                         Revised 20 September 1993
-
-Note: This information file is included in both the BSD audio driver
-distribution (bsd_audio.tar.Z) and NTP Version 3 distribution
-(xntp3.tar.Z) as the file README.irig. Both distributions can be
-obtained via anonymous ftp from louie.udel.edu in the directory pub/ntp.
-
-1. Introduction
-
-This software distribution includes modifications to the BSD audio
-driver for the Sun SPARCstation written by Van Jacobson and
-collaborators at Lawrence Berkeley National Laboratory. The
-modifications provide for the connection of a standard Inter-Range
-Instrumentation Group (IRIG) timecode signal generator and the decoding
-of the signal to produce data sufficient to synchronize a host clock to
-the IRIG signal. There are several timing receivers now on the market
-that can produce IRIG signals, including those made by Austron,
-TrueTime, Odetics and Spectracom, among others. These data can be used
-to precisely synchronize the host computer clock to within a few
-microseconds without requiring level converters or pulse generators
-necessary with the one-pulse-per-second signals also produced by these
-receivers. The current implementation of the Network Time Protocol
-Version 3 supports the modified BSD driver when installed in the SunOS
-4.1.x kernel.
-
-The specific IRIG signal format supported by the driver is designated
-IRIG-B. It consists of an amplitude-modulated 1000-Hz sinewave, where
-each symbol is encoded as ten full carrier cycles, or 10 ms in duration.
-The symbols are distinguished using a pulse-width code, where 2 ms
-corresponds to logic zero, 5 ms to logic one and 8 ms to a position
-identifier used for symbol synchronization. The complete IRIG-B message
-consists of a frame of ten fields, each field consisting of a nine
-information symbols followed by a position identifier for a total frame
-duration of one second. The first symbol in the frame is also a position
-identifier to facilitate frame synchronization.
-
-The IRIG-B signal encodes the day of year and time of day in binary-
-coded decimal (BCD) format, together with a set of control functions,
-which are not used by the driver, but included in the raw binary
-timecode. Either the BCD timecode or the combined raw timecode and BCD
-timecode can be returned in response to a read() system call. The BCD
-timecode is in handy ASCII format: "ddd hh:mm:ss*" for convenience in
-client programs. In this format the "*" status character is " " when the
-driver is operating normally and "?" when errors may be present (see
-below). In order to reduce residual errors to the greatest extent
-possible, the driver computes a timestamp based on the value of the
-kernel clock at the on-time epoch of the IRIG-B signal. In addition, the
-driver automatically adjusts for slowly varying amplitude levels of the
-IRIG-B signal and suppresses noise transients.
-
-In operation the IRIG driver interprets the IRIG-B signal in real time,
-synchronizes to the signal, demodulates the data bits and prepares the
-data to be read later. At the on-time epoch a timestamp is captured from
-the kernel clock and adjusted for the phase of the IRIG carrier signal
-relative to the 8-kHz codec sample clock. When a client program issues a
-read() request, the most recent timecode data, including a status byte
-and the corrected timestamp, are stored in a structure and returned to
-the caller. Depending on the frequency with which the driver is called,
-this may result in old data or duplicate data or even invalid data,
-should the driver be called before it has computed its first timestamp.
-
-In practice, the resulting ambiguity causes few problems. The caller
-converts the ASCII timecode returned by a read() system call to Unix
-timeval format and subtracts it from the kernel timestamp provided by
-the driver. The result is an adjustment that can be subtracted from the
-kernel time, as returned in a gettimeofday() call, for example, to
-correct for the deviation between IRIG time and kernel time. The result
-can always be relied on to within plus/minus 128 microseconds, the audio
-codec sampling interval, and ordinarily to within a few microseconds, as
-determined by the interpolation algorithm.
-
-2. Programming Interface
-
-The IRIG driver modifications are integrated in the BSD audio driver
-bsd_audio.c without affecting its usual functions in transmitting and
-receiving ordinary speech, except when enabled by specific ioctl()
-system calls. However, the driver cannot be used for both speech and
-IRIG signals at the same time. Once activated by a designated ioctl()
-call, the driver remains active until it is explicitly deactivated by
-another ioctl() call. This allows applications to configure the audio
-device and pass the pre-configured driver to other applications. Since
-the driver is currently only a receiver, it does not affect the
-operation of the BSD audio output driver.
-
-Data are read using the standard read() system call. Since the output
-formats have constant lengths, the application receives the data into a
-fixed-length buffer or structure. The read() call never blocks; it
-simply returns the most recent IRIG data received during the last
-second. It may happen that, due to unavoidable race conditions in the
-kernel, data for other than the most recent second are returned. The
-driver's internal data structure is updated as an atomic unit; thus, the
-entire structure is valid, even if it contains old data. This should
-cause no problems, since in the intended application the driver is
-called at regular intervals by a time-synchronization daemon such as
-NTP. The daemon can determine the validity of the time indication by
-checking the timecode or status byte returned with the data.
-
-The header file bsd_audioirig.h  defines the irig_time structure and
-ioctl() codes used by the driver. Following are those codes specific to
-the IRIG function of the driver. Unless indicated otherwise, the (third)
-argument of the ioctl() system call points to an integer or string.
-
-AUDIO_IRIG_OPEN
-
-     This command activates the IRIG receiver. The audio driver must be
-     opened with this command before other commands can be issued. The
-     argument is ignored. When the IRIG receiver is initialized, all
-     internal data are purged and any buffered data are lost.
-
-AUDIO_IRIG_CLOSE
-
-     This command deactivates the IRIG receiver. The argument is
-     ignored. The buffers are purged and any buffered time data are
-     lost. The original BSD audio driver functions are enabled and it
-     resumes operating normally.
-
-AUDIO_IRIG_SETFORMAT
-
-     The argument is a pointer to an integer designating the output
-     format for the IRIG data. There are currently two formats defined,
-     0 (default) and 1. If an invalid format is selected, the default
-     format is used.
-
-The data returned by a read() system call in format 0 is a character
-string in the format "ddd hh:mm:ss*\n", which consists of 13 ASCII
-characters followed by a newline terminator for a total of 14
-characters. The "*" status character is an ASCII space " " if the status
-byte determined by the driver is zero and "?" if not. This format is
-intended to be used with simple user programs that care only about the
-time to the nearest second.
-The data returned by a read() system call in format 1 is a structure
-defined in the bsd_audioirig.h header file:
-
-     struct irig_time {
-          struct timeval stamp;    /* timestamp */
-          u_char bits[13];         /* 100 irig data bits */
-          u_char status;           /* status byte */
-          char time[14];           /* time string */
-     };
-
-The irig-time.stamp is a pair of 32-bit longwords in Unix timeval
-format, as defined in the sys/time.h header file. The first word is the
-number of seconds since 1 January 1970, while the second is the number
-of microseconds in the current second. The timestamp is captured at the
-most recent on-time instant of the IRIG timecode and applies to all
-other values returned in the irig_time structure.
-
-The irig_time.bits[13] is a vector of 13 bytes to hold the 100-bit,
-zero-padded raw binary timecode, packed 8 symbols per byte. The symbol
-encoding maps IRIG one to 1 and both IRIG zero and IRIG position
-identifier to 0. The order of encoding is illustrated by the following
-diagram (the padding bits are represented by xxxx, which are set to
-zero):
-
-IRIG symbol number  00000000001111111111 . . . 8888889999999999xxxx
-                    01234567890123456789 . . . 4567890123456789xxxx
-                    -----------------------------------------------
-bits byte number    <--00--><--01--><----     ----><--11--><--12-->
-bits bit in byte    01234567012345670123 . . . 45670123456701234567
-
-The irig_time.status is a single byte with bits defined in the
-bsd_audioirig.h header file. In ordinary operation all bits of the
-status byte are zero and the " " status character is set in the ASCII
-timecode. If any of these bits are nonzero, the "?" status character is
-set in the ASCII timecode.
-
-AUDIO_IRIG_BADSIGNAL
-
-     The signal amplitude is outside tolerance limits, either in
-     amplitude or modulation depth. The indicated time may or may not be
-     in error. If the signal is too high, it may be clipped by the
-     codec, so that the pulse width cannot be reliably determined. If
-     too low, it may be obscured by noise. The nominal expectation is
-     that the peak amplitude of the signal be maintained by the codec
-     AGC at about 10 dB below the clipping level and that the modulation
-     index be at least 0.5 (6 dB).
-
-AUDIO_IRIG_BADDATA
-
-     An invalid hex code (A through F) has been found where BCD data is
-     expected. The ASCII representation of the invalid code is set to
-     "?". Errors of this type are most likely due to noise on the IRIG
-     signal due to ground loops, coupling to other noise sources, etc.
-
-AUDIO_IRIG_BADSYNC
-
-     A code element has been found where a position identifier should be
-     or a position identifier has been found where a code element should
-     be. The time is meaningless and should be disregarded. Errors of
-     this type can be due to severe noise on the IRIG signal due to
-     ground loops, coupling to other noise sources, etc., or during
-     initial acquisition of the signal.
-
-AUDIO_IRIG_BADCLOCK
-
-     Some IRIG timecode generators can indicate whether or not the
-     generator is operating correctly or synchronized to its source of
-     standard time using a designated field in the raw binary timecode.
-     Where such information is available and the IRIG decoder can detect
-     it, this bit is set when the generator reports anything except
-     normal operating conditions.
-
-AUDIO_IRIG_OLDDATA
-
-     The IRIG time has not changed since the last time it was returned
-     in a read() call. This is not normally considered an error, unless
-     it persists for longer than a few seconds, in which case it
-     probably indicates a hardware problem.
-
-The irig_time.time[14] vector is a character string in the format "ddd
-hh:mm:ss*\0", which consists of 13 ASCII characters followed by a zero
-terminator. The "*" status character is an ASCII space " " if the status
-byte is zero and "?" if not. This format is identical to format 0,
-except that in format 1 the time string is null-terminated.
-
-2.1. Programming Example
-
-The following pseudo-code demonstrates how the IRIG receiver may be used
-by a simple user program. Of course, real code should include error
-checking after each call to ensure the driver is communicating properly.
-It should also verify that the correct fields in the structure are being
-filled by the read() call.
-
-     include "bsd_audioirig.h"
-
-     int format = 1;
-     struct irig_time it;
-
-     Audio_fd = open("/dev/audio", O_RDONLY);
-     ioctl(Audio_fd, AUDIO_IRIG_OPEN, NULL);
-     ioctl(Audio_fd, AUDIO_IRIG_SETFORMAT,&format);
-     while (condition)
-          read(Audio_fd, &it, sizeof(it);
-          printf("%s\n", it.time);
-     ioctl(Audio_fd, AUDIO_IRIG_CLOSE, NULL);
-     close(Audio_fd);
-
-3. Implementation and Configuration Notes
-
-The signal level produced by most IRIG-equipped radios is on the order
-of a few volts peak-peak, which is far larger than the audio codec can
-accept; therefore, an attenuator in the form of a voltage divider is
-needed. The codec can handle IRIG signals at the microphone input from
-4.2mV to 230mV peak-peak. A suitable attenuator conists of a series-
-connected 100K-Ohm resistor at the input and a parallel-connected 1K-Ohm
-resistor at the output, both contained along with suitable connectors in
-a small aluminum box. The exact values of these resistors are not
-critical, since the IRIG driver includes an automatic level-adjustment
-capability.
-
-For the most accurate time using the IRIG signal and a particular radio,
-it may be necessary to adjust the time1 parameter of the fudge command
-to compensate for the codec delay and any additional delay due to IRIG
-processing in the radio itself. Since the codec samples at an 8-kHz
-rate, the average delay is about 62 usec; however, the delays due to the
-radios and IRIG signals themselves can vary. For instance, in the
-Austron recievers the IRIG delay is essentially zero, while in the
-Spectracom receivers the delay is about 240 usec relative to the 1-pps
-signal. In addition, the poll interval can be reduced from the usual 64
-seconds to 16 seconds to reduce wander of the local hardware clock.
-Finally, the prefer parameter can be used to bias the clock-selection
-algorithm to favor the IRIG time, which is ordinarily the best time
-available. For example, the following two lines in the NTP configuration
-file ntp.conf are appropriate for the Spectracom Netclock/1 WWVB
-Synchronized Clock with IRIG Option:
-

-fudge 127.127.6.0 time1 0.0005
-
-The time1 value of .0005 s (500 usec) was determined by actual
-measurement. Since the IRIG delay in Austron receivers is essentially
-zero, the fudge command is not necessary with these receivers. The
-correct value in case of other radios may have to be determined by
-actual measurement. A convenient way of doing this is to configure the
-PPSPPS feature in the NTP Version 3 distribution and adjust time1 until
-the 1-pps signal and IRIG signal both show the same offset.
-
-The modified BSD driver includes both the modified driver itself
-bsd_audio.c and the IRIG header file bsd_audioirig.h, as well as
-modified header files bsd_audiovar.h and bsd_audioio.h. The driver is
-installed in the same way as described in the BSD driver documentation,
-with the addition of the following define in the kernel configuration
-file:
-
-options   AUDIO_IRIG          # IRIG driver
-
-This causes the IRIG code to be included in the BSD driver, as well as a
-C-coded codec interrupt routine which replaces the assembly-coded
-routine and provides the IRIG functionality. While the C-coded routine
-is somewhat slower than the assembly-coded routine, the extra overhead
-is not expected to be significant. Note that the IRIG driver calls the
-kernel routine microtime() as included in the ppsclock directory of the
-NTP Version 3 distribution xntp3. It is highly recommended that this
-routine be installed in the kernel configuration as well. The
-instructions for doing this are contained in the ppsclock directory of
-the xntp3 distribution.

-                A Kernel Model for Precision Timekeeping
-
-                          Revised 3 April 1994
-
-Note: This memorandum is a substantial revision of RFC-1589, "A Kernel
-Model for Precision Timekeeping," March, 1994. It includes several
-changes to the daemon and user interfaces, as well as a new feature
-which disciplines the CPU clock oscillator in both time and frequency to
-a source of precision time signals. This memorandum is included in the
-distributions for the SunOS, Ultrix and OSF/1 kernels and in the NTP
-Version 3 distribution (xntp3.v.tar.Z) as the file README.kern, where v
-is the version identifier. Availability of the kernel distributions,
-which involve licensed code, will be announced separately. The NTP
-Version 3 distribution can be obtained via anonymous ftp from
-louie.udel.edu in the directory pub/ntp. In order to utilize all
-features of this distribution, the NTP version identifier should be 3q
-or later.
-
-Overview
-
-This memorandum describes an engineering model which implements a
-precision time-of-day function for a generic operating system. The model
-is based on the principles of disciplined oscillators and phase-lock
-loops (PLL) and frequency-lock loops (FLL) often found in the
-engineering literature. It has been implemented in the Unix kernels for
-several workstations, including those made by Sun Microsystems and
-Digital Equipment. The model changes the way the system clock is
-adjusted in time and frequency, as well as provides mechanisms to
-discipline its frequency to an external precision timing source. The
-model incorporates a generic system-call interface for use with the
-Network Time Protocol (NTP) or similar time synchronization protocol.
-The NTP Version 3 daemon xntpd operates with this model to provide
-synchronization limited in principle only by the accuracy and stability
-of the external timing source.
-
-This memorandum does not obsolete or update any RFC. It does not propose
-a standard protocol, specification or algorithm. It is intended to
-provoke comment, refinement and implementations for kernels not
-considered herein. While a working knowledge of NTP is not required for
-an understanding of the design principles or implementation of the
-model, it may be helpful in understanding how the model behaves in a
-fully functional timekeeping system. The architecture and design of NTP
-is described in [MIL91], while the current NTP Version 3 protocol
-specification is given in RFC-1305 [MIL92a] and a subset of the
-protocol, the Simple Network Time Protocol (SNTP), is given in RFC-1361
-[MIL92c].
-
-The model has been implemented in the Unix kernels for three Sun
-Microsystems and Digital Equipment workstations. In addition, for the
-Digital machines the model provides improved precision to one
-microsecond (us). Since these specific implementations involve
-modifications to licensed code, they cannot be provided directly.
-Inquiries should be directed to the manufacturer's representatives.
-However, the engineering model for these implementations, including a
-simulator with code segments almost identical to the implementations,
-but not involving licensed code, is available via anonymous FTP from
-host louie.udel.edu in the directory pub/ntp and compressed tar archive
-kernel.tar.Z. The NTP Version 3 distribution can be obtained via
-anonymous ftp from the same host and directory in the compressed tar
-archive xntp3.3q.tar.Z, where the version number shown as 3.3q may be
-adjusted for new versions as they occur.
-
-1. Introduction
-
-This memorandum describes a model and programming interface for generic
-operating system software that manages the system clock and timer
-functions. The model provides improved accuracy and stability for most
-computers using the Network Time Protocol (NTP) or similar time
-synchronization protocol. This memorandum describes the design
-principles and implementations of the model, while related technical
-reports discuss the design approach, engineering analysis and
-performance evaluation of the model as implemented in Unix kernels for
-modern workstations. The NTP Version 3 daemon xntpd operates with these
-implementations to provide improved accuracy and stability, together
-with diminished overhead in the operating system and network. In
-addition, the model supports the use of external timing sources, such as
-precision pulse-per-second (PPS) signals and the industry standard IRIG
-timing signals. The NTP daemon automatically detects the presence of the
-new features and utilizes them when available.
-
-There are three prototype implementations of the model presented in this
-memorandum, one each for the Sun Microsystems SPARCstation with the
-SunOS 4.1.x kernel, Digital Equipment DECstation 5000 with the Ultrix
-4.x kernel and Digital Equipment 3000 AXP Alpha with the OSF/1 V1.x
-kernel. In addition, for the DECstation 5000/240 and 3000 AXP Alpha
-machines, a special feature provides improved precision to 1 us (stock
-Sun kernels already do provide this precision). Other than improving the
-system clock accuracy, stability and precision, these implementations do
-not change the operation of existing Unix system calls which manage the
-system clock, such as gettimeofday(), settimeofday() and adjtime();
-however, if the new features are in use, the operations of
-gettimeofday() and adjtime() can be controlled instead by new system
-calls ntp_gettime() and ntp_adjtime() as described below.
-
-A detailed description of the variables and algorithms that operate upon
-them is given in the hope that similar functionality can be incorporated
-in Unix kernels for other machines. The algorithms involve only minor
-changes to the system clock and interval timer routines and include
-interfaces for application programs to learn the system clock status and
-certain statistics of the time synchronization process. Detailed
-installation instructions are given in a specific README files included
-in the kernel distributions.
-
-In this memorandum, NTP Version 3 and the Unix implementation xntp3 are
-used as an example application of the new system calls for use by a
-synchronization daemon. In principle, these system calls can be used by
-other protocols and implementations as well. Even in cases where the
-local time is maintained by periodic exchanges of messages at relatively
-long intervals, such as using the NIST Automated Computer Time Service
-[LEV89], the ability to precisely adjust the system clock frequency
-simplifies the synchronization procedures and allows the telephone call
-frequency to be considerably reduced.
-
-2. Design Approach
-
-While not strictly necessary for an understanding or implementation of
-the model, it may be helpful to briefly describe how NTP operates to
-control the system clock in a client computer. As described in [MIL91],
-the NTP protocol exchanges timestamps with one or more peers sharing a
-synchronization subnet to calculate the time offsets between peer clocks
-and the local clock. These offsets are processed by several algorithms
-which refine and combine the offsets to produce an ensemble average,
-which is then used to adjust the local clock time and frequency. The
-manner in which the local clock is adjusted represents the main topic of
-this memorandum. The goal in the enterprise is the most accurate and
-stable system clock possible with the available computer hardware and
-kernel software.
-
-In order to understand how the new model works, it is useful to review
-how most Unix kernels maintain the system clock. In the Unix design a
-hardware counter interrupts the kernel at a fixed rate: 100 Hz in the
-SunOS kernel, 256 Hz in the Ultrix kernel and 1024 Hz in the OSF/1
-kernel. Since the Ultrix timer interval (reciprocal of the rate) does
-not evenly divide one second in microseconds, the kernel adds 64 us once
-each second, so the timescale consists of 255 advances of 3906 us plus
-one of 3970 us. Similarly, the OSF/1 kernel adds 576 us once each
-second, so its timescale consists of 1023 advances of 976 us plus one of
-1552 us.
-
-2.1. Mechanisms to Adjust Time and Frequency
-
-In most Unix kernels it is possible to slew the system clock to a new
-offset relative to the current time by using the adjtime() system call.
-To do this the clock frequency is changed by adding or subtracting a
-fixed amount (tickadj) at each timer interrupt (tick) for a calculated
-number of timer interrupts. Since this calculation involves dividing the
-requested offset by tickadj, it is possible to slew to a new offset with
-a precision only of tickadj, which is usually in the neighborhood of 5
-us, but sometimes much larger. This results in a roundoff error which
-can accumulate to an unacceptable degree, so that special provisions
-must be made in the clock adjustment procedures of the synchronization
-daemon.
-
-In order to implement a frequency discipline function, it is necessary
-to provide time offset adjustments to the kernel at regular adjustment
-intervals using the adjtime() system call. In order to reduce the system
-clock jitter to the regime consistent with the model, it is necessary
-that the adjustment interval be relatively small, in the neighborhood of
-1 s. However, the Unix adjtime() implementation requires each offset
-adjustment to complete before another one can be begun, which means that
-large adjustments must be amortized over possibly many adjustment
-intervals. The requirement to implement the adjustment interval and
-compensate for roundoff error considerably complicates the synchronizing
-daemon implementation.
-
-In the new model this scheme is replaced by another that represents the
-system clock as a multiple-word, precision-time variable in order to
-provide very precise clock adjustments. At each timer interrupt a
-precisely calibrated quantity is added to the kernel time variable and
-overflows propagated as required. The quantity is computed as in the NTP
-local clock model described in [MIL92b], which operates as an adaptive-
-parameter, first-order, type-II phase-lock loop (PLL). In principle,
-this PLL design can provide precision control of the system clock
-oscillator within 1 us and frequency to within parts in 10^11. While
-precisions of this order are surely well beyond the capabilities of the
-CPU clock oscillator used in typical workstations, they are appropriate
-using precision external oscillators, as described below.
-
-The PLL design is identical to the one originally implemented in NTP and
-described in [MIL92b]. In the original design the software daemon
-simulates the PLL using the adjtime() system call; however, the daemon
-implementation is considerably complicated by the considerations
-described above. The modified kernel routines implement the PLL in the
-kernel using precision time and frequency representations, so that these
-complications are avoided. A new system call ntp_adjtime() is called
-only as each new time update is determined, which in NTP occurs at
-intervals of from 16 s to 1024 s. In addition, doing frequency
-compensation in the kernel means that the system clock runs true even if
-the daemon were to cease operation or the network paths to the primary
-synchronization source fail.
-
-In the new model the new ntp_adjtime() operates in a way similar to the
-original adjtime() system call, but does so independently of adjtime(),
-which continues to operate in its traditional fashion. When used with
-NTP, it is the design intent that settimeofday() or adjtime() be used
-only for system clock adjustments greater than +-128 ms, although the
-dynamic range of the new model is much larger at +-512 ms. It has been
-the Internet experience that the need to change the system clock in
-increments greater than +-128 ms is extremely rare and is usually
-associated with a hardware or software malfunction or system reboot.
-
-The easiest way to set the time is with the settimeofday() system call;
-however, this can under some conditions cause the clock to jump
-backwards. If this cannot be tolerated, adjtime() can be used to slew
-the clock to the new value without running backward or affecting the
-frequency discipline process. Once the system clock has been set within
-+-128 ms, the ntp_adjtime() system call is used to provide periodic
-updates including the time offset, maximum error, estimated error and
-PLL time constant. With NTP the update interval and time constant depend
-on the measured delay and dispersion; however, the scheme is quite
-forgiving and neither moderate loss of updates nor variations in the
-update interval are serious.
-
-2.2 Daemon and Application Interface
-
-Unix application programs can read the system clock using the
-gettimeofday() system call, which returns only the system time and
-timezone data. For some applications it is useful to know the maximum
-error of the reported time due to all causes, including clock reading
-errors, oscillator frequency errors and accumulated latencies on the
-path to the primary synchronization source. However, in the new model
-the PLL adjusts the system clock to compensate for its intrinsic
-frequency error, so that the time error expected in normal operation
-will usually be much less than the maximum error. The programming
-interface includes a new system call ntp_gettime(), which returns the
-system time, as well as the maximum error and estimated error. This
-interface is intended to support applications that need such things,
-including distributed file systems, multimedia teleconferencing and
-other real-time applications. The programming interface also includes a
-new system call ntp_adjtime(), which can be used to read and write
-kernel variables for time and frequency adjustment, PLL time constant,
-leap-second warning and related data.
-
-In addition, the kernel adjusts the indicated maximum error to grow by
-an amount equal to the maximum oscillator frequency tolerance times the
-elapsed time since the last update. The default engineering parameters
-have been optimized for update intervals in the order of 64 s. As shown
-in [MIL93], this is near the optimum interval for NTP used with ordinary
-room-temperature quartz oscillators. For other intervals the PLL time
-constant can be adjusted to optimize the dynamic response over intervals
-of 16-1024 s. Normally, this is automatically done by NTP. In any case,
-if updates are suspended, the PLL coasts at the frequency last
-determined, which usually results in errors increasing only to a few
-tens of milliseconds over a day using typical modern workstations.
-
-While any synchronization daemon can in principle be modified to use the
-new system calls, the most likely will be users of the NTP Version 3
-daemon xntpd. The xntpd code determines whether the new system calls are
-implemented and automatically reconfigures as required. When
-implemented, the daemon reads the frequency offset from a system file
-and provides it and the initial time constant via ntp_adjtime(). In
-subsequent calls to ntp_adjtime(), only the time offset and time
-constant are affected. The daemon reads the frequency from the kernel
-using ntp_adjtime() at intervals of about one hour and writes it to a
-system file. This information is recovered when the daemon is restarted
-after reboot, for example, so the sometimes extensive training period to
-learn the frequency separately for each oscillator can be avoided.
-
-2.3. Precision Clocks for DECstation 5000/240 and 3000 AXP Alpha
-
-The stock microtime() routine in the Ultrix kernel for Digital Equipment
-MIPS-based workstations returns system time to the precision of the
-timer interrupt interval, which is in the 1-4 ms range. However, in the
-DECstation 5000/240 and possibly other machines of that family, there is
-an undocumented IOASIC hardware register that counts system bus cycles
-at a rate of 25 MHz. The new microtime() routine for the Ultrix kernel
-uses this register to interpolate system time between timer interrupts.
-This results in a precision of 1 us for all time values obtained via the
-gettimeofday() and ntp_gettime() system calls. For the Digital Equipment
-3000 AXP Alpha, the architecture provides a hardware Process Cycle
-Counter and a machine instruction (rpcc) to read it. This counter
-operates at the fundamental frequency of the CPU clock or some
-submultiple of it, 133.333 MHz for the 3000/400 for example. The new
-microtime() routine for the OSF/1 kernel uses this counter in the same
-fashion as the Ultrix routine. Support for this feature is conditionally
-compiled in the kernel only if the MICRO option is used in the kernel
-configuration file.
-
-In both the Ultrix and OSF/1 kernels the gettimeofday() and
-ntp_gettime() system call use the new microtime() routine, which returns
-the interpolated value to 1-us resolution, but does not change the
-kernel time variable. Therefore, other routines that access the kernel
-time variable directly and do not call either gettimeofday(),
-ntp_gettime() or microtime() will continue their present behavior. The
-microtime() feature is independent of other features described here and
-is operative even if the kernel PLL or new system calls have not been
-implemented.
-
-The SunOS kernel already includes a system clock with 1-us resolution;
-so, in principle, no microtime() routine is necessary. An existing
-kernel routine uniqtime() implements this function, but it is coded in
-the C language and is rather slow at 42-85 us per call on a SPARCstation
-IPC. A replacement microtime() routine coded in assembler language is
-available in the NTP Version 3 distribution and is much faster at about
-3 us per call. Note that, as explained later, this routine should be
-called at an interrupt priority level not greater than that of the timer
-interrupt routine. Otherwise, it is possible to miss a tick increment,
-with result the time returned can be late by one tick. This is always
-true in the case of gettimeofday() and ntp_gettime(), but might not be
-true in other cases, such as when using the PPS signal described later
-in this memorandum.
-
-2.4. External Time and Frequency Discipline
-
-The overall accuracy of a time synchronization subnet with respect to
-Coordinated Universal Time (UTC) depends on the accuracy and stability
-of the primary synchronization source, usually a radio or satellite
-receiver, and the CPU clock oscillator of the primary server. As
-discussed in [MIL93], the traditional interface using a ASCII serial
-timecode and RS232 port precludes the full accuracy of most radio
-clocks. In addition, the poor frequency stability of typical CPU clock
-oscillators limits the accuracy, whether or not precision time sources
-are available. There are, however, several ways in which the system
-clock accuracy and stability can be improved to the degree limited only
-by the accuracy and stability of the synchronization source and the
-jitter of the interface and operating system.
-
-Many radio clocks produce special signals that can be used by external
-equipment to precisely synchronize time and frequency. Most produce a
-pulse-per-second (PPS) signal that can be read via a modem-control lead
-of a serial port and some produce a special IRIG signal that can be read
-directly by a bus peripheral, such as the KSI/Odetics TPRO IRIG SBus
-interface, or indirectly via the audio codec of some workstations, as
-described in [MIL93]. In the NTP Version 3 daemon xntpd, the PPS signal
-can be used to augment the less precise ASCII serial timecode to improve
-accuracy to the order of a few tens of microseconds. Support is also
-included in the NTP distribution for the TPRO interface, as well as the
-audio codec; however, the latter requires a modified kernel audio driver
-contained in the compressed tar archive bsd_audio.tar.Z in the same host
-and directory as the NTP Version 3 distribution mentioned previously.
-2.4.1. PPS Signal
-
-The most convenient way to interface a PPS signal to a computer is
-usually with a serial port and RS232-compatible signal; however, the PPS
-signal produced by most radio clocks and laboratory instruments is
-usually a TTL pulse signal. Therefore, some kind of level
-converter/pulse generator is necessary to adapt the PPS signal to a
-serial port. An example design, including schematic and printed-circuit
-board artwork, is in the compressed tar archive gadget.tar.Z in the same
-host and directory as the NTP Version 3 distribution mentioned
-previously. There are several ways the PPS signal can be used in
-conjunction with the NTP Version 3 daemon xntpd, as described in [MIL93]
-and in the documentation included in the distribution.
-
-The NTP Version 3 distribution includes a special ppsclock module for
-the SunOS 4.1.x kernel that captures the PPS signal presented via a
-modem-control lead of a serial port. Normally, the ppsclock module
-produces a timestamp at each transition of the PPS signal and provides
-it to the synchronization daemon for integration with the serial ASCII
-timecode, also produced by the radio clock. With the conventional PLL
-implementation in either the daemon or the kernel as described in
-[MIL93], the accuracy of this scheme is limited by the intrinsic
-stability of the CPU clock oscillator to a millisecond or two, depending
-on environmental temperature variations.
-
-The ppsclock module has been modified to in addition call a new kernel
-routine hardpps() once each second. In addition, the Ultrix 4.3 kernel
-has been modified to provide a similar functionality. The hardpps()
-routine compares the timestamp with a sample of the CPU clock oscillator
-in order to discipline the oscillator to the time and frequency of the
-PPS signal. Using this method, the time accuracy is improved to
-typically 20 us or less and frequency stability a few parts in 10^8,
-which is about two orders of magnitude better than the undisciplined
-oscillator. The new feature is conditionally compiled in the code
-described below only if the PPS_SYNC option is used in the kernel
-configuration file.
-
-When using the PPS signal to adjust the time, there is a problem with
-some kernels which is very difficult to fix. The serial port interrupt
-routine often operates at an interrupt priority level above the timer
-interrupt routine. Thus, as explained below, it is possible that a tick
-increment can be missed and the time returned late by one tick. It may
-happen that, if the CPU clock oscillator frequency is close to the PPS
-oscillator frequency (less than a few ppm), this condition can persist
-for two or more successive PPS interrupts. A useful workaround in the
-code is to use a glitch detector and median filter to process the PPS
-sample offsets. The glitch detector suppresses offset bursts greater
-than half the tick interval and which last less than 30 successive PPS
-interrupts. The median filter ranks the offsets in a moving window of
-three samples and uses the median as the output and the difference
-between the other two as a dispersion measure.
-
-2.4.2. External Clocks
-
-It is possible to replace the system clock function with an external bus
-peripheral. The TPRO device mentioned previously can be used to provide
-IRIG-synchronized time with a precision of 1 us. A driver for this
-device tprotime.c and header file tpro.h are included in the
-kernel.tar.Z distribution mentioned previously. Using this device, the
-system clock is read directly from the interface; however, the device
-does not record the year, so special provisions have been made to obtain
-the year from the kernel time variable and initialize the driver
-accordingly. Support for this feature is conditionally compiled in the
-kernel only if the EXT_CLOCK and TPRO options are used in the kernel
-configuration file.
-
-While the system clock function is provided directly by the microtime()
-routine in the driver, the kernel time variable must be disciplined as
-well, since not all system timing functions use the microtime() routine.
-This is done by measuring the time difference between the microtime()
-clock and kernel time variable and using it to adjust the kernel PLL as
-if the adjustment were provided by an external peer and NTP.
-
-A good deal of error checking is done in the TPRO driver, since the
-system clock is vulnerable to a misbehaving radio clock, IRIG signal
-source, interface cables and TPRO device itself. Unfortunately, there is
-no practical way to utilize the extensive diversity and redundancy
-capabilities available in the NTP synchronization daemon. In order to
-avoid disruptions that might occur if the TPRO time is far different
-from the kernel time variable, the latter is used instead of the former
-if the difference between the two exceeds 1000 s; presumably in that
-case operator intervention is required.
-
-2.4.2. External Oscillators
-
-Even if a source of PPS or IRIG signals is not available, it is still
-possible to improve the stability of the system clock through the use of
-a specialized bus peripheral. In order to explore the benefits of such
-an approach, a special SBus peripheral called HIGHBALL has been
-constructed. The device includes a pair of 32-bit hardware counters in
-Unix timeval format, together with a precision, oven-controlled quartz
-oscillator with a stability of a few parts in 10^9. A driver for this
-device hightime.c and header file high.h are included in the
-kernel.tar.Z distribution mentioned previously. Support for this feature
-is conditionally compiled in the kernel only if the EXT_CLOCK and
-HIGHBALL options are used in the kernel configuration file.
-
-Unlike the external clock case, where the system clock function is
-provided directly by the microtime() routine in the driver, the HIGHBALL
-counter offsets with respect to UTC must be provided first. This is done
-using the ordinary kernel PLL, but controlling the counter offsets
-directly, rather than the kernel time variable. At first, this might
-seem to defeat the purpose of the design, since the jitter and wander of
-the synchronization source will affect the counter offsets and thus the
-accuracy of the time. However, the jitter is much reduced by the PLL and
-the wander is small, especially if using a radio clock or another
-primary server disciplined in the same way. In practice, the scheme
-works to reduce the incidental wander to a few parts in 10^8, or about
-the same as using the PPS signal.
-
-As in the previous case, the kernel time variable must be disciplined as
-well, since not all system timing functions use the microtime() routine.
-However, the kernel PLL cannot be used for this, since it is already in
-use providing offsets for the HIGHBALL counters. Therefore, a special
-correction is calculated from the difference between the microtime()
-clock and the kernel time variable and used to adjust the kernel time
-variable at the next timer interrupt. This somewhat roundabout approach
-is necessary in order that the adjustment does not cause the kernel time
-variable to jump backwards and possibly lose or duplicate a timer event.
-
-2.5 Other Features
-
-It is a design feature of the NTP architecture that the system clocks in
-a synchronization subnet are to read the same or nearly the same values
-before during and after a leap-second event, as declared by national
-standards bodies. The new model is designed to implement the leap event
-upon command by an ntp_adjtime() argument. The intricate and sometimes
-arcane details of the model and implementation are discussed in [MIL92b]
-and [MIL93]. Further details are given in the technical summary later in
-this memorandum.
-3. Technical Summary
-
-In order to more fully understand the workings of the model, a stand-
-alone simulator kern.c and header file timex.h are included in the
-kernel.tar.Z distribution mentioned previously. In addition, an example
-kernel module kern_ntptime.c which implements the ntp_gettime() and
-ntp_adjtime() system calls is included. Neither of these programs
-incorporate licensed code. Since the distribution is somewhat large, due
-to copious comments and ornamentation, it is impractical to include a
-listing of these programs in this memorandum. In any case, implementors
-may choose to snip portions of the simulator for use in new kernel
-designs; but, due to formatting conventions, this would be difficult if
-included in this memorandum.
-
-The kern.c program is an implementation of an adaptive-parameter, first-
-order, type-II phase-lock loop. The system clock is implemented using a
-set of variables and algorithms defined in the simulator and driven by
-explicit offsets generated by the main() routine in the program. The
-algorithms include code fragments almost identical to those in the
-machine-specific kernel implementations and operate in the same way, but
-the operations can be understood separately from any licensed source
-code into which these fragments may be integrated. The code fragments
-themselves are not derived from any licensed code. The following
-discussion assumes that the simulator code is available for inspection.
-
-3.1. PLL Simulation
-
-The simulator operates in conformance with the analytical model
-described in [MIL92b]. The main() program operates as a driver for the
-fragments hardupdate(), hardclock(), second_overflow(), hardpps() and
-microtime(), although not all functions implemented in these fragments
-are simulated. The program simulates the PLL at each timer interrupt and
-prints a summary of critical program variables at each time update.
-
-There are three defined options in the kernel configuration file
-specific to each implementation. The PPS_SYNC option provides support
-for a pulse-per-second (PPS) signal, which is used to discipline the
-frequency of the CPU clock oscillator. The EXT_CLOCK option provides
-support for an external kernel-readable clock, such as the KSI/Odetics
-TPRO IRIG interface or HIGHBALL precision oscillator, both for the SBus.
-The TPRO option provides support for the former, while the HIGHBALL
-option provides support for the latter. External clocks are implemented
-as the microtime() clock driver, with the specific source code selected
-by the kernel configuration file.
-
-The PPS signal is carefully monitored for error conditions which can
-affect accuracy, stability and reliability. The time_status kernel
-variable contains bits that both control the use of the PPS signal and
-reveal its operational status. The function of each bit is described in
-a later section of this memo.
-
-3.1.1. The hardupdate() Fragment
-
-The hardupdate() fragment is called by ntp_adjtime() as each update is
-computed to adjust the system clock phase and frequency. Note that the
-time constant is in units of powers of two, so that multiplies can be
-done by simple shifts. The phase variable is computed as the offset
-divided by the time constant, but clamped to a maximum (for robustness).
-Then, the time since the last update is computed and clamped to a
-maximum and to zero if initializing. The offset is multiplied (sorry
-about the ugly multiply) by the result and divided by the square of the
-time constant and then added to the frequency variable. Note that all
-shifts are assumed to be positive and that a shift of a signed quantity
-to the right requires a little dance.
-
-The STA_PLL and STA_PPSTIME status bits, which are set by the
-ntp_adjtime() system call, serve to enable or inhibit the kernel PLL and
-PPS time-discipline functions. The STA_PPSSIGNAL status bit is set by
-the hardpps() code fragment when the PPS signal is present and operating
-within nominal bounds. Time discipline from the PPS signal operates only
-if both the STA_PPSTIME and STA_PPSSIGNAL bits are set; otherwise, the
-discipline operates from the offset given in the ntp_adjtime() system
-call. In the intended mode of operation, the synchronization daemon sets
-STA_PLL to enable the PLL when first initialized, then sets STA_PPSTIME
-when reliable synchronization to within +-128 ms has been achieved with
-either a radio clock or external peer. The daemon can detect and
-indicate this condition for monitoring purposes by noting that both
-STA_PPSTIME and STA_PPSSIGNAL are set.
-
-With the defines given in the program and header files, the maximum time
-offset is determined by the size in bits of the long type (32 or 64)
-less the SHIFT_UPDATE scale factor (12) or at least 20 bits (signed).
-The scale factor is chosen so that there is no loss of significance in
-later steps, which may involve a right shift up to SHIFT_UPDATE bits.
-This results in a time adjustment range over +-512 ms. Since
-time_constant must be greater than or equal to zero, the maximum
-frequency offset is determined by the SHIFT_USEC scale factor (16) or at
-least 16 bits (signed). This results in a frequency adjustment range
-over +-31,500 ppm.
-
-In the addition step, the value of offset * mtemp is not greater than
-MAXPHASE * MAXSEC = 31 bits (signed), which will not overflow a long add
-on a 32-bit machine. There could be a loss of precision due to the right
-shift of up to 12 bits, since time_constant is bounded at 6. This
-results in a net worst-case frequency resolution of about .063 ppm,
-which is not significant for most quartz oscillators. The worst case
-could be realized only if the NTP peer misbehaves according to the
-protocol specification.
-
-The time_offset value is clamped upon entry. The time_phase variable is
-an accumulator, so is clamped to the tolerance on every call. This helps
-to damp transients before the oscillator frequency has been stabilized,
-as well as to satisfy the correctness assertions if the time
-synchronization protocol or implementation misbehaves.
-
-3.1.2. The hardclock() Fragment
-
-The hardclock() fragment is inserted in the hardware timer interrupt
-routine at the point the system clock is to be incremented by the value
-of tick. Previous to this fragment the time_update variable has been
-initialized to the tick increment plus the value computed by the
-adjtime() system call in the stock Unix kernel, normally plus/minus the
-tickadj value, which is usually in the order of 5 us. The time_phase
-variable, which represents the instantaneous phase of the system clock,
-is advanced by time_adj, which is calculated in the second_overflow()
-fragment described below. If the value of time_phase exceeds 1 us in
-scaled units, time_update is increased by the (signed) excess and
-time_phase retains the residue.
-
-In those cases where a PPS signal is connected by a serial port
-operating at an interrupt priority level greater than the timer
-interrupt, special consideration should be given the location of the
-hardclock() fragment in the timer interrupt routine. The system clock
-should be advanced as early in the routine as possible, preferably
-before the hardware timer interrupt flag is cleared. This reduces or
-eliminates the possibility that the microtime() routine may latch the
-time after the flag is cleared, but before the system clock is advanced,
-which results in a returned time late by one tick.
-
-Except in the case of an external oscillator such as the HIGHBALL
-interface, the hardclock() fragment advances the system clock by the
-value of tick plus time_update. However, in the case of an external
-oscillator, the system clock is obtained directly from the interface and
-time_update used to discipline that interface instead. However, the
-system clock must still be disciplined as explained previously, so the
-value of clock_cpu computed by the second_overflow() fragment is used
-instead.
-
-3.1.3. The second_overflow() Fragment
-
-The second_overflow() fragment is inserted at the point where the
-microseconds field of the system time variable is being checked for
-overflow. Upon overflow the maximum error time_maxerror is increased by
-time_tolerance to reflect the maximum time offset due to oscillator
-frequency error. Then, the increment time_adj to advance the kernel time
-variable is calculated from the (scaled) time_offset and time_freq
-variables updated at the last call to the hardclock() fragment.
-
-The phase adjustment is calculated as a (signed) fraction of the
-time_offset remaining, where the fraction is added to time_adj, then
-subtracted from time_offset. This technique provides a rapid convergence
-when offsets are high, together with good resolution when offsets are
-low. The frequency adjustment is the sum of the (scaled) time_freq
-variable, an adjustment necessary when the tick interval does not evenly
-divide one second fixtick and PPS frequency adjustment pps_freq (if
-configured).
-
-The scheme of approximating exact multiply/divide operations with shifts
-produces good results, except when an exact calculation is required,
-such as when the PPS signal is being used to discipline the CPU clock
-oscillator frequency as described below. As long as the actual
-oscillator frequency is a power of two in Hz, no correction is required.
-However, in the SunOS kernel the clock frequency is 100 Hz, which
-results in an error factor of 0.78. In this case the code increases
-time_adj by a factor of 1.25, which results in an overall error less
-than three percent.
-
-On rollover of the day, the leap-second state machine described below
-determines whether a second is to be inserted or deleted in the
-timescale. The microtime() routine insures that the reported time is
-always monotonically increasing.
-
-3.1.4. The hardpps() Fragment
-
-The hardpps() fragment is operative only if the PPS_SYNC option is
-specified in the kernel configuration file. It is called from the serial
-port driver or equivalent interface at the on-time transition of the PPS
-signal. The code operates as a first-order, type-I, frequency-lock loop
-(FLL) controlled by the difference between the frequency represented by
-the pps_freq variable and the frequency of the hardware clock
-oscillator. It also provides offsets to the hardupdate() fragment in
-order to discipline the system clock time.
-
-In order to avoid calling the microtime() routine more than once for
-each PPS transition, the interface requires the calling program to
-capture the system time and hardware counter contents at the on-time
-transition of the PPS signal and provide a pointer to the timestamp
-(Unix timeval) and counter contents as arguments to the hardpps() call.
-The hardware counter contents are determined by saving the microseconds
-field of the system time, calling the microtime() routine, and
-subtracting the saved value. If a microseconds overflow has occurred
-during the process, the resulting microseconds value will be negative,
-in which case the caller adds 1000000 to normalize the microseconds
-field.
-
-In order to avoid large jitter when the PPS interrupt occurs during the
-timer interrupt routine before the system clock is advanced, a glitch
-detector is used. The detector latches when an offset exceeds a
-threshold tick/2 and stays latched until either a subsequent offset is
-less than the threshold or a specified interval MAXGLITCH (30 s) has
-elapsed. As long as the detector remains latched, it outputs the offset
-immediately preceding the latch, rather than the one received.
-
-A three-stage median filter is used to suppress jitter less than the
-glitch threshold. The median sample drives the PLL, while the difference
-between the other two samples represents the time dispersion. Time
-dispersion samples are averaged and used as a jitter estimate. If this
-estimate exceeds a threshold MAXTIME/2 (100 us), an error bit
-STA_PPSJITTER is raised in the status word.
-
-The frequency of the hardware oscillator is determined from the
-difference in hardware counter readings at the beginning and end of the
-calibration interval divided by the duration of the interval. However,
-the oscillator frequency tolerance, as much as 100 ppm, may cause the
-difference to exceed the tick value, creating an ambiguity. In order to
-avoid this ambiguity, the hardware counter value at the beginning of the
-interval is increased by the current pps_freq value once each second,
-but computed modulo the tick value. At the end of the interval, the
-difference between this value and the value computed from the hardware
-counter is the control signal for the FLL.
-
-Control signal samples which exceed the frequency tolerance MAXFREQ (100
-ppm) are discarded, as well as samples resulting from excessive interval
-duration jitter. In these cases an error bit STA_PPSERROR is raised in
-the status word. Surviving samples are then processed by a three-stage
-median filter. The median sample drives the FLL, while the difference
-between the other two samples represents the frequency dispersion.
-Frequency dispersion samples are averaged and used as a stabiity
-estimate. If this estimate is below a threshold MAXFREQ/4 (25 ppm), the
-median sample is used to correct the oscillator frequency pps_freq with
-a weight expressed as a shift PPS_AVG (2).
-
-Initially, an approximate value for the oscillator frequency is not
-known, so the duration of the calibration interval must be kept small to
-avoid overflowing the tick. The time difference at the end of the
-calibration interval is measured. If greater than tick/4, the interval
-is reduced by half. If less than this fraction for four successive
-calibration intervals, the interval is doubled. This design
-automatically adapts to nominal jitter in the PPS signal, as well as the
-value of tick. The duration of the calibration interval is set by the
-pps_shift variable as a shift in powers of two. The minimum value
-PPS_SHIFT (2) is chosen so that with the highest CPU oscillator
-frequency 1024 Hz and frequency tolerance 100 ppm the tick will not
-overflow. The maximum value PPS_SHIFTMAX (8) is chosen such that the
-maximum averaging time is about 1000 s as determined by measurements of
-Allan variance [MIL93].
-
-Should the PPS signal fail, the current frequency estimate pps_freq
-continues to be used, so the nominal frequency remains correct subject
-only to the instability of the undisciplined oscillator. The procedure
-to save and restore the frequency estimate works as follows. When
-setting the frequency from a file, the time_freq value is set as the
-file value minus the pps_freq value; when retrieving the frequency, the
-two values are added before saving in the file. This scheme provides a
-seamless interface should the PPS signal fail or the kernel
-configuration change. Note that the frequency discipline is active
-whether or not the synchronization daemon is active. Since all Unix
-systems take some time after reboot to build a running system, usually
-by that time the discipline process has already settled down and the
-initial transients due to frequency discipline have damped out.
-3.1.4. External Clock Interface
-
-The external clock driver interface is implemented with two routines,
-microtime(), which returns the current clock time, and clock_set(),
-which furnishes the apparent system time derived from the kernel time
-variable. The latter routine is called only when the clock is set using
-the settimeofday() system call, but can be called from within the
-driver, such as when the year rolls over, for example.
-
-In the stock SunOS kernel and modified Ultrix and OSF/1 kernels, the
-microtime() routine returns the kernel time variable plus an
-interpolation between timer interrupts based on the contents of a
-hardware counter. In the case of an external clock, such as described
-above, the system clock is read directly from the hardware clock
-registers. Examples of external clock drivers are in the tprotime.c and
-hightime.c routines included in the kernel.tar.Z distribution.
-
-The external clock routines return a status code which indicates whether
-the clock is operating correctly and the nature of the problem, if not.
-The return code is interpreted by the ntp_gettime() system call, which
-transitions the status state machine to the TIME_ERR state if an error
-code is returned. This is the only error checking implemented for the
-external clock in the present version of the code.
-
-The simulator has been used to check the PLL operation over the design
-envelope of +-512 ms in time error and +-100 ppm in frequency error.
-This confirms that no overflows occur and that the loop initially
-converges in about 15 minutes for timer interrupt rates from 50 Hz to
-1024 Hz. The loop has a normal overshoot of a few percent and a final
-convergence time of several hours, depending on the initial time and
-frequency error.
-
-3.2. Leap Seconds
-
-It does not seem generally useful in the user application interface to
-provide additional details private to the kernel and synchronization
-protocol, such as stratum, reference identifier, reference timestamp and
-so forth. It would in principle be possible for the application to
-independently evaluate the quality of time and project into the future
-how long this time might be "valid." However, to do that properly would
-duplicate the functionality of the synchronization protocol and require
-knowledge of many mundane details of the platform architecture, such as
-the subnet configuration, reachability status and related variables. For
-the curious, the ntp_adjtime() system call can be used to reveal some of
-these mysteries.
-
-However, the user application may need to know whether a leap second is
-scheduled, since this might affect interval calculations spanning the
-event. A leap-warning condition is determined by the synchronization
-protocol (if remotely synchronized), by the timecode receiver (if
-available), or by the operator (if awake). This condition is set by the
-synchronization daemon on the day the leap second is to occur (30 June
-or 31 December, as announced) by specifying in a ntp_adjtime() system
-call a status bit of either STA_DEL, if a second is to be deleted, or
-STA_INS, if a second is to be inserted. Note that, on all occasions
-since the inception of the leap-second scheme, there has never been a
-deletion, nor is there likely to be one in future. If the bit is
-STA_DEL, the kernel adds one second to the system time immediately
-following second 23:59:58 and resets the clock state to TIME_WAIT. If
-the bit is STA_INS, the kernel subtracts one second from the system time
-immediately following second 23:59:59 and resets the clock stateto
-TIME_OOP, in effect causing system time to repeat second 59. Immediately
-following the repeated second, the kernel resets the clock status to
-TIME_WAIT.
-
-Following the leap operations, the clock remains in the TIME_WAIT state
-until both the STA_DEL and STA_INS status bits are reset. This provides
-both an unambiguous indication that a leap recently occured, as well as
-time for the daemon or operator to clear the warning condition.
-
-Depending upon the system call implementation, the reported time during
-a leap second may repeat (with the TIME_OOP return code set to advertise
-that fact) or be monotonically adjusted until system time "catches up"
-to reported time. With the latter scheme the reported time will be
-correct before and shortly after the leap second (depending on the
-number of microtime() calls during the leap second), but freeze or
-slowly advance during the leap second itself. However, Most programs
-will probably use the ctime() library routine to convert from timeval
-(seconds, microseconds) format to tm format (seconds, minutes,...). If
-this routine is modified to use the ntp_gettime() system call and
-inspect the return code, it could simply report the leap second as
-second 60.
-
-3.3. Clock Status State Machine
-
-The various options possible with the system clock model described in
-this memorandum require a careful examination of the state transitions,
-status indications and recovery procedures should a crucial signal or
-interface fail. In this section is presented a prototype state machine
-designed to support leap second insertion and deletion, as well as
-reveal various kinds of errors in the synchronization process. The
-states of this machine are decoded as follows:
-
-     TIME_OK        If a PPS signal or external clock is present, it is
-                    working properly and the system clock is derived
-                    from it. If not, the synchronization daemon is
-                    working properly and the system clock is
-                    synchronized to a radio clock or one or more peers.
-
-     TIME_INS       An insertion of one second in the system clock has
-                    been declared following the last second of the
-                    current day, but has not yet been executed.
-
-     TIME_DEL       A deletion of the last second of the current day has
-                    been declared, but not yet executed.
-
-     TIME_OOP       An insertion of one second in the system clock has
-                    been declared following the last second of the
-                    current day. The second is in progress, but not yet
-                    completed. Library conversion routines should
-                    interpret this second as 23:59:60.
-
-     TIME_WAIT      The scheduled leap event has occurred, but the
-                    STA_DEL and STA_INS status bits have not yet been
-                    cleared.
-
-     TIME_ERROR     Either (a) the synchronization daemon has declared
-                    the protocol is not working properly, (b) all
-                    sources of outside synchronization have been lost or
-                    (c) a PPS signal or external clock is present, but
-                    not working properly.
-
-In all states the system clock is derived from either a PPS signal or
-external clock, if present, or the kernel time variable, if not. If a
-PPS error condition is recognized, the PPS signal is disabled and
-ntp_adjtime() updates are used instead. If an external clock error
-condition is recognized, the external clock is disabled and the kernel
-time variable is used instead.
-
-The state machine makes a transition once each second at an instant
-where the microseconds field of the kernel time variable overflows and
-one second is added to the seconds field. However, this condition is
-checked when the timer overflows, which may not coincide with the actual
-seconds increment. This may lead to some interesting anomalies, such as
-a status indication of a leap second in progress (TIME_OOP) when the
-leap second has already expired. This ambiguity is unavoidable, unless
-the timer interrupt is made synchronous with the system clock.
-
-The following state transitions are executed automatically by the kernel
-at rollover of the microseconds field:
-
-     any state -> TIME_ERROR  This transition occurs when an error
-                         condition is recognized and continues as long
-                         as the condition persists. The error indication
-                         overrides the normal state indication, but does
-                         not affect the actual clock state. Therefore,
-                         when the condition is cleared, the normal state
-                         indication resumes.
-
-     TIME_OK->TIME_DEL   This transition occurs if the STA_DEL bit is
-                         set in the status word.
-
-     TIME_OK->TIME_INS   This transition occurs if the STA_INS bit is
-                         set in the status word.
-
-     TIME_INS->TIME_OOP  This transition occurs immediately following
-                         second 86,400 of the current day when an
-                         insert-second event has been declared.
-
-     TIME_OOP->TIME_WAIT This transition occurs immediately following
-                         second 86,401 of the current day; that is, one
-                         second after entry to the TIME_OOP state.
-
-     TIME_DEL->TIME_WAIT This transition occurs immediately following
-                         second 86,399 of the current day when a delete-
-                         second event has been declared.
-
-     TIME_WAIT->TIME_OK  This transition occurs when the STA_DEL and
-                         STA_INS bits are cleared by an ntp_adjtime()
-                         call.
-
-The following table summarizes the actions just before, during and just
-after a leap-second event. Each line in the table shows the UTC and NTP
-times at the beginning of the second. The left column shows the behavior
-when no leap event is to occur. In the middle column the state machine
-is in TIME_INS at the end of UTC second 23:59:59 and the NTP time has
-just reached 400. The NTP time is set back one second to 399 and the
-machine enters TIME_OOP. At the end of the repeated second the machine
-enters TIME_OK and the UTC and NTP times are again in correspondence. In
-the right column the state machine is in TIME_DEL at the end of UTC
-second 23:59:58 and the NTP time has just reached 399. The NTP time is
-incremented, the machine enters TIME_OK and both UTC and NTP times are
-again in correspondence.

-To determine local midnight without fuss, the kernel code simply finds
-the residue of the time.tv_sec (or time.tv_sec + 1) value mod 86,400,
-but this requires a messy divide. Probably a better way to do this is to
-initialize an auxiliary counter in the settimeofday() routine using an
-ugly divide and increment the counter at the same time the time.tv_sec
-is incremented in the timer interrupt routine. For future embellishment.
-
-4. Programming Model and Interfaces
-
-This section describes the programming model for the synchronization
-daemon and user application programs. The ideas are based on suggestions
-from Jeff Mogul and Philip Gladstone and a similar interface designed by
-the latter. It is important to point out that the functionality of the
-original Unix adjtime() system call is preserved, so that the modified
-kernel will work as the unmodified one, should the new features not be
-in use. In this case the ntp_adjtime() system call can still be used to
-read and write kernel variables that might be used by a synchronization
-daemon other than NTP, for example.
-
-The kernel routines use the clock state variable time_state, which
-records whether the clock is synchronized, waiting for a leap second,
-etc. The value of this variable is returned as the result code by both
-the ntp_gettime() and ntp_adjtime() system calls. It is set implicitly
-by the STA_DEL and STA_INS status bits, as described previously. Values
-presently defined in the timex.h header file are as follows:
-
-     TIME_OK        0         no leap second warning
-     TIME_INS       1         insert leap second warning
-     TIME_DEL       2         delete leap second warning
-     TIME_OOP       3         leap second in progress
-     TIME_WAIT      4         leap second has occured
-     TIME_ERROR     5         clock not synchronized
-
-In case of a negative result code, the kernel has intercepted an invalid
-address or (in case of the ntp_adjtime() system call), a superuser
-violation.
-
-4.1. The ntp_gettime() System Call
-
-The syntax and semantics of the ntp_gettime() call are given in the
-following fragment of the timex.h header file. This file is identical,
-except for the SHIFT_HZ define, in the SunOS, Ultrix and OSF/1 kernel
-distributions. (The SHIFT_HZ define represents the logarithm to the base
-2 of the clock oscillator frequency specific to each system type.) Note
-that the timex.h file calls the syscall.h system header file, which must
-be modified to define the SYS_ntp_gettime system call specific to each
-system type. The kernel distributions include directions on how to do
-this.
-
-     /*

-The ntp_gettime() system call returns three read-only (ro) values in the
-ntptimeval structure: the current time in unix timeval format plus the
-maximum and estimated errors in microseconds. While the 32-bit long data
-type limits the error quantities to something more than an hour, in
-practice this is not significant, since the protocol itself will declare
-an unsynchronized condition well below that limit. In the NTP Version 3
-specification, if the protocol computes either of these values in excess
-of 16 seconds, they are clamped to that value and the system clock
-declared unsynchronized.
-
-Following is a detailed description of the ntptimeval structure members.
-
-struct timeval time (ro)
-
-     This member is the current system time expressed as a Unix timeval
-     structure. The timeval structure consists of two 32-bit words; the
-     first is the number of seconds past 1 January 1970 assuming no
-     intervening leap-second insertions or deletions, while the second
-     is the number of microseconds within the second.
-
-long maxerror (ro)
-
-     This member is the value of the time_maxerror kernel variable,
-     which represents the maximum error of the indicated time relative
-     to the primary synchronization source, in microseconds. For NTP,
-     the value is initialized by a ntp_adjtime() call to the
-     synchronization distance, which is equal to the root dispersion
-     plus one-half the root delay. It is increased by a small amount
-     (time_tolerance) each second to reflect the maximum clock frequency
-     error. This variable is provided bu a ntp-adjtime() system call and
-     modified by the kernel, but is otherwise not used by the kernel.
-
-long esterror (ro)
-
-     This member is the value of the time_esterror kernel variable,
-     which represents the expected error of the indicated time relative
-     to the primary synchronization source, in microseconds. For NTP,
-     the value is determined as the root dispersion, which represents
-     the best estimate of the actual error of the system clock based on
-     its past behavior, together with observations of multiple clocks
-     within the peer group. This variable is provided bu a ntp-adjtime()
-     system call, but is otherwise not used by the kernel.
-
-4.2. The ntp_adjtime() System Call
-
-The syntax and semantics of the ntp_adjtime() call are given in the
-following fragment of the timex.h header file. Note that, as in the
-ntp_gettime() system call, the syscall.h system header file must be
-modified to define the SYS_ntp_adjtime system call specific to each
-system type. In the fragment, rw = read/write, ro = read-only, wo =
-write-only.

-The ntp_adjtime() system call is used to read and write certain time-
-related kernel variables summarized below. Writing these variables can
-only be done in superuser mode. To write a variable, the mode structure
-member is set with one or more bits, one of which is assigned each of
-the following variables in turn. The current values for all variables
-are returned in any case; therefore, a mode argument of zero means to
-return these values without changing anything.
-
-Following is a description of the timex structure members.
-
-mode (wo)
-
-     This is a bit-coded variable selecting one or more structure
-     members, with one bit assigned each member. If a bit is set, the
-     value of the associated member variable is copied to the
-     corresponding kernel variable; if not, the member is ignored. The
-     bits are assigned as given in the following, with the variable name
-     indicated in parens. Note that the precision, tolerance and PPS
-     variables are determined by the kernel and cannot be changed by
-     ntp_adjtime().
-
-     MOD_OFFSET     0x0001    time offset (offset)
-     MOD_FREQUENCY  0x0002    frequency offset (frequency)
-     MOD_MAXERROR   0x0004    maximum time error (maxerror)
-     MOD_ESTERROR   0x0008    estimated time error (esterror)
-     MOD_STATUS     0x0010    clock status (status)
-     MOD_TIMECONST  0x0020    pll time constant (constant)
-     MOD_CLKB       0x4000    set clock B
-     MOD_CLKA       0x8000    set clock A
-
-     Note that the MOD_CLK0 and MOD_CLK1 bits are intended for those
-     systems where more than one hardware clock is available for backup,
-     such as in Tandem Non-Stop computers. Presumably, in such cases
-     each clock would have its own oscillator and require a separate PLL
-     for each. Refinements to this model are for further study. The
-     interpretation of these bits is as follows:
-
-offset (rw)
-
-     If selected, this member specifies the time adjustment, in
-     microseconds. The absolute value must be less than MAXPHASE
-     (128000) microseconds defined in the timex.h header file. On
-     return, this member contains the residual offset remaining between
-     a previously specified offset and the current system time, in
-     microseconds.
-
-frequency (rw)
-
-     If selected, this member replaces the value of the time_frequency
-     kernel variable. The value is in ppm, with the integer part in the
-     high order 16 bits and fraction in the low order 16 bits. The
-     absolute value must be in the range less than MAXFREQ (100) ppm
-     defined in the timex.h header file.
-
-     The time_freq variable represents the frequency offset of the CPU
-     clock oscillator. It is recalculated as each update to the system
-     clock is determined by the offset member of the timex structure. It
-     is usually set from a value stored in a file when the
-     synchronization daemon is first started. The current value is
-     usually retrieved via this member and written to the file about
-     once per hour.
-
-maxerror (rw)
-
-     If selected, this member replaces the value of the time_maxerror
-     kernel variable, in microseconds. This is the same variable as in
-     the ntp_getime() system call.
-
-esterror (rw)
-
-     If selected, this member replaces the value of the time_esterror
-     kernel variable, in microseconds. This is the same variable as in
-     the ntp_getime() system call.
-
-int status (rw)
-
-     If selected, this member replaces the value of the time_status
-     kernel variable. This variable controls the state machine used to
-     insert or delete leap seconds and shows the status of the
-     timekeeping system, PPS signal and external oscillator, if
-     configured.
-
-     STA_PLL        0x0001    enable PLL updates (r/w)
-     STA_PPSFREQ    0x0002    enable PPS freq discipline (r/w)
-     STA_PPSTIME    0x0004    enable PPS time discipline (r/w)
-     STA_INS        0x0010    insert leap (r/w)
-     STA_DEL        0x0020    delete leap (r/w)
-     STA_UNSYNC     0x0040    clock unsynchronized (r/w)
-     STA_PPSSIGNAL  0x0100    PPS signal present (r)
-     STA_PPSJITTER  0x0200    PPS signal jitter exceeded (r)
-     STA_PPSWANDER  0x0400    PPS signal wander exceeded (r)
-     STA_PPSERROR   0x0800    PPS signal calibration error (r)
-     STA_CLOCKERR   0x1000    clock hardware fault (r)
-
-     The interpretation of these bits is as follows:
-
-     STA_PLL        set/cleared by the caller to enable PLL updates
-
-     STA_PPSFREQ    set/cleared by the caller to enable PPS frequency
-                    discipline
-
-     STA_PPSTIME    set/cleared by the caller to enable PPS time
-                    discipline
-
-     STA_INS        set by the caller to insert a leap second at the end
-                    of the current day; cleared by the caller after the
-                    event
-
-     STA_DEL        set by the caller to delete a leap second at the end
-                    of the current day; cleared by the caller after the
-                    event
-
-     STA_UNSYNC     set/cleared by the caller to indicate clock
-                    unsynchronized (e.g., when no peers are reachable)
-
-     STA_PPSSIGNAL  set/cleared by the hardpps() fragment to indicate
-                    PPS signal present
-
-     STA_PPSJITTER  set/cleared by the hardpps() fragment to indicates
-                    PPS signal jitter exceeded
-
-     STA_PPSWANDER  set/cleared by the hardpps() fragment to indicates
-                    PPS signal wander exceeded
-
-     STA_PPSERROR   set/cleared by the hardpps() fragment to indicates
-                    PPS signal calibration error
-
-     STA_CLOCKERR   set/cleared by the external hardware clock driver to
-                    indicate hardware fault
-
-     An error condition is raised when (a) either STA_UNSYNC or
-     STA_CLOCKERR is set (loss of synchronization), (b) STA_PPSFREQ or
-     STA_PPSTIME is set and STA_PPSSIGNAL is clear (loss of PPS signal),
-     (c) STA_PPSTIME and STA_PPSJITTER are both set (jitter exceeded),
-     (d) STA_PPSFREQ is set and either STA_PPSWANDER or STA_PPSERROR is
-     set (wander exceeded). An error condition results in a system call
-     return code of TIME_ERROR.
-
-constant (rw)
-
-     If selected, this member replaces the value of the time_constant
-     kernel variable. The value must be between zero and MAXTC (6)
-     defined in the timex.h header file.
-
-     The time_constant variable determines the bandwidth or "stiffness"
-     of the PLL. The value is used as a shift between zero and MAXTC
-     (6), with the effective PLL time constant equal to a multiple of (1
-     << time_constant), in seconds. For room-temperature quartz
-     oscillators, the recommended default value is 2, which corresponds
-     to a PLL time constant of about 900 s and a maximum update interval
-     of about 64 s. The maximum update interval scales directly with the
-     time constant, so that at the maximum time constant of 6, the
-     update interval can be as large as 1024 s.
-
-     Values of time_constant between zero and 2 can be used if quick
-     convergence is necessary; values between 2 and 6 can be used to
-     reduce network load, but at a modest cost in accuracy. Values above
-     6 are appropriate only if an precision external oscillator is
-     present.
-
-precision (ro)
-
-     This is the current value of the time_precision kernel variable in
-     microseconds.
-
-     The time_precision variable represents the maximum error in reading
-     the system clock, in microseconds. It is usually based on the
-     number of microseconds between timer interrupts (tick), 10000 us
-     for the SunOS kernel, 3906 us for the Ultrix kernel, 976 us for the
-     OSF/1 kernel. However, in cases where the time can be interpolated
-     between timer interrupts with microsecond resolution, such as in
-     the stock SunOS kernel and modified Ultrix and OSF/1 kernels, the
-     precision is specified as 1 us. In cases where a PPS signal or
-     external oscillator is available, the precision can depend on the
-     operating condition of the signal or oscillator. This variable is
-     determined by the kernel for use by the synchronization daemon, but
-     is otherwise not used by the kernel.
-
-tolerance (ro)
-
-     This is the current value of the time_tolerance kernel variable.
-     The value is in ppm, with the integer part in the high order 16
-     bits and fraction in the low order 16 bits.
-
-     The time_tolerance variable represents the maximum frequency error
-     in ppm of the particular CPU clock oscillator and is a property of
-     the hardware; however, in principle it could change as result of
-     the presence of external discipline signals, for instance.
-
-     The recommended value for time_tolerance MAXFREQ (200) ppm is
-     appropriate for room-temperature quartz oscillators used in typical
-     workstations. However, it can change due to the operating condition
-     of the PPS signal and/or external oscillator. With either the PPS
-     signal or external oscillator, the recommended value for MAXFREQ is
-     100 ppm.
-
-The following members are defined only if the PPS_SYNC option is
-specified in the kernel configuration file. These members are useful
-primarily as a monitoring and evalutation tool. These variables can be
-written only by the kernel.
-
-ppsfreq (ro)
-
-     This is the current value of the pps_freq kernel variable, which is
-     the CPU clock oscillator frequency offset relative to the PPS
-     discipline signal. The value is in ppm, with the integer part in
-     the high order 16 bits and fraction in the low order 16 bits.
-
-jitter (ro)
-
-     This is the current value of the pps_jitter kernel variable, which
-     is the average PPS time dispersion measured by the time-offset
-     median filter, in microseconds.
-
-shift (ro)
-
-     This is the current value of the pps_shift kernel variable, which
-     determines the duration of the calibration interval as the value of
-     1 << pps_shift, in seconds.
-stabil (ro)
-
-     This is the current value of the pps_stabil kernel variable, which
-     is the average PPS frequency dispersion measured by the frequency-
-     offset median filter. The value is in ppm, with the integer part in
-     the high order 16 bits and fraction in the low order 16 bits.
-
-jitcnt (ro)
-
-     This is the current value of the pps_jitcnt kernel variable, counts
-     the number of PPS signals where the average jitter exceeds the
-     threshold MAXTIME (200 us).
-
-calcnt (ro)
-
-     This is the current value of the pps_calcnt kernel variable, which
-     counts the number of frequency calibration intervals. The duration
-     of these intervals can range from 4 to 256 seconds, as determined
-     by the pps_shift kernel variable.
-
-errcnt (ro)
-
-     This is the current value of the pps_errcnt kernel variable, which
-     counts the number of frequency calibration cycles where (a) the
-     apparent frequency offset is greater than MAXFREQ (100 ppm) or (b)
-     the interval jitter exceeds tick * 2.
-
-stbcnt (ro)
-
-     This is the current value of the pps_discnt kernel variable, which
-     counts the number of calibration intervals where the average
-     stability exceeds the threshold MAXFREQ / 4 (25 ppm).

-1. Introduction
-
-It most cases it is possible using NTP to synchronize a number of hosts
-on an Ethernet or moderately loaded T1 network to a radio clock within a
-few tens of milliseconds with no particular care in selecting the radio
-clock or configuring the servers on the network. This may be adequate
-for the majority of applications; however, modern workstations and high
-speed networks can do much better than that, generally to within some
-fraction of a millisecond, by using special care in the design of the
-hardware and software interfaces.
-
-The timekeeping accuracy of a NTP-synchronized host depends on two
-quantities: the delay due to hardware and software processing and the
-accumulated jitter due to such things as clock reading precision and
-varying latencies in hardware and software queuing. Processing delays
-directly affect the timekeeping accuracy, unless minimized by systematic
-analysis and adjustment. Jitter, on the other hand, can be essentially
-removed, as long as the statistical properties are unbiased, by the low-
-pass filtering of the phase-lock loop incorporated in the NTP local
-clock model.
-
-This note discusses issues in the connection of external time sources
-such as radio clocks and related timing signals to a primary (stratum-1)
-NTP time server. Of principal concern are various techniques that can be
-utilized to improve the accuracy and precision of the time accuracy and
-frequency stability. Radio clocks are most often connected to a time
-server using a serial asynchronous port. Much of the discussion in this
-memorandum has to do with ways in which the delay incurred in this type
-of connection can be controlled and ways in which the jitter due to
-various causes can be minimized.
-
-However, there are ways other than serial ports to connect a radio
-clock, including special purpose hardware devices for some
-architectures, and even unusual applications of existing interface
-devices, such as the audio codec provided in some systems. Many of these
-methods can yield accuracies as good as any attainable with a serial
-port. For those radio clocks equipped with an IRIG-B signal output, for
-example, a hardware device is available for the Sun SPARCstation; see
-the xntpd.8 manual page in the doc directory of the NTP Version 3
-distribution for further information. In addition, it is possible to
-decode the IRIG-B signal using the audio codec included in the Sun
-SPARCstation and a special kernel driver described in the irig.txt file
-in the doc directory of the NTP Version 3 distribution. These devices
-will not be discussed further in this memorandum.
-
-2. Connection via Serial Port
-
-Most radio clocks produce an ASCII timecode with a precision only to the
-millisecond. This results in a maximum peak-to-peak (p-p) jitter in the
-clock readings of one millisecond. However, assuming the read requests
-are statistically independent of the clock update times, the reading
-error is uniformly distributed over the millisecond, so that the average
-over a large number of readings will make the clock appear 0.5 ms late.
-To compensate for this, it is only necessary to add 0.5 ms to its
-reading before further processing by the NTP algorithms.
-
-Radio clocks are usually connected to the host computer using a serial
-port operating at a typical speed of 9600 baud. The on-time reference
-epoch for the timecode is usually the start bit of a designated
-character, usually <CR>, which is part of the timecode. The UART chip
-implementing the serial port most often has a sample clock of eight to
-16 times the basic baud rate. Assuming the sample clock starts midway in
-the start bit and continues to midway in the first stop bit, this
-creates a processing delay of 10.5 baud times, or about 1.1 ms, relative
-to the start bit of the character. The jitter contribution is usually no
-more than a couple of sample-clock periods, or about 26 usec p-p. This
-is small compared to the clock reading jitter and can be ignored. Thus,
-the UART delay can be considered constant, so the hardware contribution
-to the total mean delay budget is 0.5 + 1.1 = 1.6 ms.
-
-In some kernel serial port drivers, in particular, the Sun zs driver,
-an intentional delay is introduce in input character processing when the
-first character is received after an idle period. A batch of characters
-is passed to the calling program when either (a) a timeout in the
-neighborhood of 10 ms expires or (b) an input buffer fills up. The
-intent in this design is to reduce the interrupt load on the processor
-by batching the characters where possible. Obviously, this can cause
-severe problems for precision timekeeping. It is possible to patch the
-zs driver to eliminate the jitter due to this cause; contact the author
-for further details. However, there is a better solution which will be
-described later in this note. The problem does not appear to be present
-in the Serial/Parallel Controller (SPC) for the SBus, which contains
-eight serial asynchronous ports along with a parallel port. The
-measurements referred to below were made using this controller.
-
-Good timekeeping depends strongly on the means available to capture an
-accurate sample of the local clock or timestamp at the instant the stop
-bit of the on-time character is found; therefore, the code path delay
-between the character interrupt routine and the first place a timestamp
-can be captured is very important, since on some systems such as Sun
-SPARCstations, this path can be astonishingly long. The Sun scheduling
-mechanisms involve both a hardware interrupt queue and a software
-interrupt queue. Entries are made on the hardware queue as the interrupt
-is signalled and generally with the lowest latency, estimated at 20-30
-microseconds (usec) for a SPARC 4/65 IPC. Then, after minimal
-processing, an entry is made on the software queue for later processing
-in order of software interrupt priority. Finally, the software interrupt
-unblocks the NTP daemon which calculates the current local clock offset
-and introduces corrections as required.
-
-Opportunities exist to capture timestamps at the hardware interrupt
-time, software interrupt time and at the time the NTP daemon is
-activated, but these involve various degrees of kernel trespass and
-hardware gimmicks. To gain some idea of the severity of the errors
-introduced at each of these stages, measurements were made using a Sun
-4/65 IPC and a test setup that results in an error between the host
-clock and a precision time source (calibrated cesium clock) no greater
-than 0.1 ms. The total delay from the on-time epoch to when the NTP
-daemon is activated was measured at 8.3 ms in an otherwise idle system,
-but increased on rare occasion to over 25 ms under load, even when the
-NTP daemon was operated at the highest available software priority
-level. Since 1.6 ms of the total delay is due to the hardware, the
-remaining 6.7 ms represents the total code path delay accounting for all
-software processing from the hardware interrupt to the NTP daemon.
-
-It is commonly observed that the latency variations (jitter) in typical
-real-time applications scale as the processing delay. In the case above,
-the ratio of the maximum observed delay (25 ms) to the baseline code
-path delay (8.3 ms) is about three. It is natural to expect that this
-ratio remain the same or less as the code path between the hardware
-interrupt and where the timestamp is captured is reduced. However, in
-general this requires trespass on kernel facilities and/or making use of
-features not common to all or even most Unix implementations. In order
-to assess the cost and benefits of increasingly more aggressive insult
-to the hardware and software of the system, it is useful to construct a
-budget of the code path delay at each of the timestamp opportunity
-times. For instance, on Unix systems which include support for the SIGIO
-facility, it is possible to intervene at the time the software interrupt
-is serviced. The NTP daemon code uses this facility, when available, to
-capture a timestamp and save it along with the data in a buffer for
-later processing. This reduces the total code path delay from 6.7 ms to
-3.5 ms on an otherwise idle system. This reduction applies to all input
-processing, including network interfaces and serial ports.
-
-3. The CLK Mode
-
-By far the best place to capture the timestamp is right in the kernel
-interrupt routine, but this gerally requires intruding in the code
-itself, which can be intricate and architecture dependent. The next best
-place is in some routine close to the interrupt routine on the code
-path. There are two ways to do this, depending on the ancestry of the
-Unix operating system variant. Older systems based primarily on the
-original Unix 4.3bsd support what is called a line discipline module,
-which is a hunk of code with more-or-less well defined interface
-specifications that can get in the way, so to speak, of the code path
-between the interrupt routine and the remainder of the serial port
-processing. Newer systems based on System V STREAMS can do the same
-thing using what is called a streams module. Both approaches are
-supported in the NTP Version 3 distribution, as described in the README
-files in the kernel directory of the distribution. In either case,
-header and source files have to be copied to the kernel build tree and
-certain tables in the kernel have to be modified. In neither case,
-however, are kernel sources required. In order to take advantage of
-this, the clock driver must include code to activate the feature and
-extract the timestamp. At present, this support is included in the clock
-drivers for the Spectracom WWVB clock (WWVB define), the PSTI/Traconex
-WWV/WWVH clock (PST define) and a special one-pulse-per-second (pps)
-signal (PPSCLK define) described later. If justified, support can be
-easily added to most other clock drivers as well. For future reference,
-these modules operating with supported drivers will be called the CLK
-support.
-
-The CLK line discipline and STREAMS modules operate in the same way.
-They look for a designated character, usually <CR>, and stuff a Unix
-timestamp in the data stream following that character whenever it is
-found. Eventually, the data arrive at the particular clock driver
-configured in the NTP Version 3 distribution. The driver then uses the
-timestamp as a precise reference epoch, subject to the earlier
-processing delays and jitter budget, for future reference. In order to
-gain some insight as to the effectiveness of this approach, measurements
-were made using the same test setup described above. The total delay
-from the on-time epoch to the instant when the timestamp is captured was
-measured at 3.5 ms. Thus, the code path delay is this value less the
-hardware delay 3.5 - 1.6 = 1.9 ms.
-
-While the improvement in accuracy in the baseline case is significant,
-there is another factor, at least in Sun systems, that makes it even
-more worthwhile. When processing the code path up to the CLK module, the
-priority is apparently higher than for processing beyond it. In case of
-heavy CPU activity, this can lead to relatively long tails in the
-processing delays for the driver, which of course are avoided by
-capturing the timestamp early in the code path.
-
-4. The PPSCLK Mode
-
-Many timing receivers can produce a 1-pps signal of considerably better
-precision than the ASCII timecode. Using this signal, it is possible to
-avoid the 1-ms p-p jitter and 1.6 ms hardware timecode adjustment
-entirely. However, a device is required to interface this signal to the
-hardware and operating system. In general, this requires some sort of
-level converter and pulse generator that can turn the 1-pps signal on-
-time transition into a valid character. An example of such a device is
-described in the gadget directory of the NTP Version 3 distribution.
-Although many different circuit designs could be used as well, this
-particular device generates a single 26-usec start bit for each 1-pps
-signal on-time transition. This appears to the UART operating at 38.4K
-baud as an ASCII DEL (hex FF).
-
-Now, assuming a serial port can be dedicated to this purpose, a source
-of 1-pps character interrupts is available and can be used to provide a
-precision reference. The NTP Version 3 daemon can be configured to
-utilize this feature by specifying the PPSCLK define, which requires the
-CLK module and gadget box described above. The character resulting from
-each 1-pps signal on-time transition is intercepted by the CLK module
-and a timestamp is inserted in the data stream. An interrupt is created
-for the device driver, which reads the timestamp and discards the DEL
-character. Since the timestamp is captured at the on-time transition,
-the seconds-fraction portion is the offset between the local clock and
-the on-time epoch less the UART delay of 273 usec at 38.4K baud. If the
-local clock is within +-0.5 second of this epoch, as determined by other
-means, the local clock correction is taken as the offset itself, if
-between zero and 0.5 s, and the offset minus one second, if between 0.5
-and 1.0 s. In the NTP daemon the resulting correction is first processed
-by a multi-stage median/trimmed mean filter to remove residual jitter
-and then processed by the usual NTP algorithms.
-
-The baseline delay between the on-time transition and the timestamp
-capture was measured at 400+-10 usec on an otherwise idle test system.
-As the UART delay at 38.4K baud is about 270 usec, the difference, 130
-usec, must be due to the hardware interrupt latency plus the time to
-call the microtime() routine which actually reads the system clock and
-microsecond counter. For these measurements the assembly-coded version
-of this routine described in the ppsclock directory of the NTP Version 3
-distribution was used. This routine reduces the time to read the system
-clock from 42-85 usec with the native Sun C-coded routine to about 3
-usec using the microtime() assembly-coded routine and can be ignored.
-Thus, the 130 usec must be accounted for in interrupt service, register
-window, context switching, streams operations and measurement
-uncertainty, which is probably not unreasonable. The reason for the
-difference between the this figure and the previously calculated value
-of 1.9 ms for the CLK module and serial ASCII timecode is probably due
-to the fact that all STREAMS modules other than the CLK module were
-removed, since the serial port is not used for ordinary ASCII data.
-
-An interesting feature of this approach is that the 1-pps signal is not
-necessarily associated with any particular radio clock and, indeed,
-there may be no such clock at all. Some precision timekeeping equipment,
-such as cesium clocks, VLF receivers and LORAN-C timing receivers
-produce only a precision 1-pps signal and rely on other mechanisms to
-resolve the second of the day and day of the year. It is possible for an
-NTP-synchronized host to derive the latter information using other NTP
-peers, presumably properly synchronized within +-0.5 second, and to
-remove residual jitter using the 1-pps signal. This makes it quite
-practical to deliver precision time to local clients when the subnet
-paths to remote primary servers are heavily congested. In extreme cases
-like this, it has been found useful to increase the tracking aperture
-from +-128 ms to as high as +-512 ms.
-
-In the current implementation the radio timecode and 1-pps signal are
-separately processed. The timecode capture and CLK support, if provided
-by the radio driver, operate the same way whether or not the PPSCLK
-support is enabled. If the local clock is reliably synchronized within
-+-0.5 s and the 1-pps signal has been valid for some number of seconds,
-its offset rather than whatever synchronization source has been selected
-is used instead. However, while a this procedure delivers a new offset
-estimate every second, the local clock is updated only as each valid
-update is computed for the peer selected as the source of
-synchronization.
-
-However, there is a hazard to the use of the 1-pps signal in this way if
-the radio generating the 1-pps signal misbehaves or loses
-synchronization with its transmitter. In such a case the radio might
-indicate the error, but the system has no way to associate the error
-with the 1-pps signal. To deal with this problem the prefer parameter
-described in the xntpd.8 man page in the doc directory of the NTP
-Version 3 distribution can be used both to cause the clock selection
-algorithm to choose a preferred peer, all other things being equal, as
-well as associate the error indications in such a way that the 1-pps
-signal will be disregarded if the peer stops providing valid updates,
-such as would occur in an error condition. The prefer parameter can be
-used in other situations as well when preference is to be given a
-particular source of synchronization.
-
-5. The PPS Mode
-
-For the ultimate accuracy and lowest jitter, it would be best to
-eliminate the UART and capture the 1-pps on-time transition directly
-using an appropriate interface. This is in fact possible using a
-modified serial port driver and data lead in the serial port interface
-cable. In this scheme, described in detail in the ppsclock directory of
-the NTP Version 3 distribution, the 1-pps source is connected via the
-previously described gadget box to the carrier-detect lead of a serial
-port. Happily, this can be the same port used for a radio clock, for
-example, or another unrelated serial device. The scheme, referred to
-subsequently as the PPS mode, is specific to the SunOS 4.1.x kernel and
-requires a special STREAMS module. Instructions on how to build the
-kernel are also included in that directory.
-
-Except for special-purpose interface modules, such as the KSI/Odetics
-TPRO IRIG-B decoder and the modified audio driver for the IRIG-B signal
-mentioned previously, the PPS mode provides the most accurate and
-precise timestamp available. There is essentially no latency and the
-timestamp is captured within 20-30 usec of the on-time epoch.
-
-The PPS mode requires the PPSPPS define and one of the radio clock
-serial ports to be selected as the PPS interface. This is the port which
-handles the 1-pps signal; however, the signal path has nothing to do
-with the ordinary serial data path; the two signals are not related,
-other than by the need to activate the PPS mode and pass the file
-descriptor to a common processing routine. Thus, for the port to be
-selected for the PPS function, the define for the associated radio clock
-needs to have a PPS suffix. In case of multiple radio clocks on a single
-time server, the PPS suffix is necessary on only one of them; more than
-one PPS suffix would be an error.
-
-The PPS mode works just like the CLK mode in the treatment of the prefer
-parameter and indicated peer errors. As in the CLK mode, only the offset
-within the second is used and only when the offset is less than +-0.5 s.
-However, the precision of the clock adjustments is usually so fine that
-the error budget is dominated by the inherent short-term stability of
-typical computer local clock oscillators. Therefore, it is advisable to
-reduce the poll interval for the preferred peer from the default 64 s to
-something less, like 16 s. This is done using the minpoll and maxpoll
-parameters of the peer or server command associated with the clock.
-These parameters take as arguments a power of 2, in seconds, which
-becomes the poll interval and, indirectly, affects the bandwidth of the
-tracking loop.
-
-6. Results and Conclusions
-
-It is clear from the above that substantial improvements in timekeeping
-accuracy are possible with varying degrees of hardware and software
-intrusion. While the ultimate accuracy depends on the jitter and wander
-characteristics of the computer local oscillator, it is possible to
-reduce jitter to a negligible degree simply by processing with the NTP
-phase-lock loop and local clock algorithms. The residual jitter using
-the PPS mode on a Sun4 IPC is typically in the 40-100 usec range, while
-the wander is rarely more than twice that under typical environmental
-room conditions.

-                         Revised 5 August 1994
-
-Support for most of the commonly available radio clocks is included in
-the default configuration of xntpd. Individual clocks can be activated
-by configuration file commands, specifically the server and fudge
-commands described in the xntpd.8 man page. This file contains

-Radio clocks by convention have addresses in the form 127.127.t.u, where

-A radio clock is specified in the configuration using the server command
-
-     server 127.127.t.u [ prefer ] [ mode m ]
-
-where t is the type number above and u can be in the range 0-3,
-conventionally 1. Ordinarily, this is the only command necessary to
-configure a radio clock. The optional prefer keyword can be used to
-modify the clock selection algorithm as described in Appendix B. For
-those clock drivers that support multiple modes of operation, the
-optional mode parameter selects which one. This parameter affects the
-operation of each driver as described in Appendix A.
-
-In rare cases a fudge command is necessary to specify additional
-details. This command has the following syntax
-
-fudge 127.127.t.u [stratum s] [refid r] [time1 t1] [time2 t2] [flags]
-and must follow the corresponding server command in the configuration
-file. The optional fields following the clock address are interpreted as
-follows:
-
-stratum s The s, a decimal number in the range 0-15, overrides the
-          default stratum assigned by the driver.
-
-refid r   The r, a 4-character, null-terminated ASCII string, overrides
-          the reference identifier assigned by the driver.
-
-time1 t1  The t1, a fixed-point decimal number in seconds, specifies a
-          constant to be added to the time offset produced by the
-          driver. This provides a way to correct a systematic error or
-          bias on the part of the particular clock.
-
-time2 t2  The t2, a fixed-point decimal number, is interpreted in a
-          driver-dependent way. See the descriptions of specific clock
-          drivers in Appendix A.
-
-There are four optional flags named flag1, flag2, flag3 and flag4. A
-flag is specified in the form <keyword> <value>, where <keyword> is one
-of the flag names and <value> is either 0 or 1, as appropriate. Two of
-the flags are generic and are interpreted by all applicable drivers, and
-two are driver dependent. The generic ones are as follows:
-
-flag4     This flag is used to enable detailed status monitoring and
-          event recording. The data collected are written to the
-          clockstats file maintained by the filegen utility (See the
-          xntpd.8 man page). This file is normally processed by a cron
-          job run once per day to produce summary statistics and
-          performance data. The ./scripts/stats directory contains a
-          number of shell and awk scripts for this, as well as S-
-          language programs that produce PostScript plots of performance
-          data.
-
-flag3     This flag is used with Sun SPARCstation baseboard serial ports
-          to assign the ppsclock streams driver for a 1-pps signal
-          produced by some radio clocks and timekeeping devices. See the
-          dscription of the PPS Clock Discipline Driver (type 22) in
-          Appendix A for further information.
-
-Note that the fudge factors above can be changed at run time using the
-xntpdc program (see the xntpdc.8 man page). This program does not have
-to be run on the server machine itself, since it communicates with the
-xntpd daemon using cryptographically authenticated messages.
-
-The PPS Signal
-
-Some radio clocks and related timekeeping gear have a pulse-per-second
-(PPS) signal that can be used to discipline the local clock oscillator
-to a high degree of precision, typically to the order less than 50 us in
-time and 0.1 ppm in frequency. The PPS signal can be connected in either
-of two ways, either via the data leads of a serial port or via the modem
-control leads. Either way requires conversion of the PPS signal, usually
-at TTL levels, to RS232 levels, which can be done using a circuit such
-as described in the ./gadget directory of the xntp3 distribution.
-
-The data leads interface requires regenerating the PPS pulse and
-converting to RS232 signal levels, so that the pulse looks like a
-legitimate ASCII character. The tty_clk module in the ./kernel directory
-inserts a timestamp following this character in the input data stream.
-The driver uses this timestamp to determine the time of arrival of the
-PPS pulse to within 26 us at 38.4 kbps while eliminating error due to
-operating system queues and service times. In order to use the tty_clk
-module, the xntp3 distribution must be compiled with CLK defined.
-The modem control leads interface requires converting to RS232 levels
-and connecting to the carrier detect (CD) lead of a serial port. The
-ppsclock streams module in the ./ppsclock directory is used to capture a
-timestamp upon transition of the PPS signal. The driver reads the latest
-timestamp with a designated ioctl() system call to determine the time of
-arrival of the PPS pulse to within a few tens of microseconds. In order
-to use the ppsclock module, the xntp3 distribution must be compiled with
-PPS defined.
-
-Both of these mechanisms are supported by the ATOM_PPS reference clock
-driver described in Appendix A. This driver is ordinarily used in
-conjunction with another clock driver that supports the radio clock that
-produces the PPS pulse. This driver furnishes the coarse timecode used
-to disambiguate the seconds numbering of the PPS pulse itself. The NTP
-daemon mitigates between the radio clock driver and ATOM_PPS driver as
-described in Appendix B in order to provide the most accurate time,
-while respecting the various types of equipment failures that could
-happen.
-
-For the utmost time quality, a number of Unix system kernel
-modifications can be made as described in the README.magic and
-README.kernel files. Specifically, the ppsclock module can be used to
-interface the PPS signal directly to the kernel for use as discipline
-sources for both time and frequency. These sources can be separately
-enabled and monitored using the ntp_adjtime() system call described in
-README.kernel and the ./include/sys/timex.h header file in the xntp3
-distribution. In order to use the kernel PPS signal, the xntp3
-distribution must be compiled with KERNEL_PLL defined.
-
-In some configurations may have multiple radio clocks, each with PPS
-outputs, as well as a kernel modified to use the PPS signal. In order to
-provide the highest degree of redundancy and survivability, the kernel
-PPS discipline, tty_clk module and ppsclock module may all be in use at
-the same time, each backing up the other. The sometimes complicated
-mitigation rules are described in Appendix B.
-
-Debugging Hints
-
-The ntpq and xntpdc utility programs can be used to debug reference
-clocks, either on the server itself or from another machine elsewhere in
-the network. The server is compiled, installed and started using the
-command-line switches described in the xntpd.8 man page. The first thing
-to look for are error messages on the system log. If none occur, the
-daemon has started, opened the devices specified and waiting for peers
-and radios to come up.
-
-The next step is to be sure the RS232 messages, if used, are getting to
-and from the clock. The most reliable way to do this is with an RS232
-tester and to look for data flashes as the driver polls the clock and/or
-as data arrive from the clock. Our experience is that the overwhelming
-fraction of problems occurring during installation are due to problems
-such as miswired connectors or improperly configured radio clocks at
-this stage.
-
-If RS232 messages are getting to and from the clock, the variables of
-interest can be inspected using the ntpq program and various commands
-described in the ntpq.8 man page. First, use the pe and as commands to
-display a pair of billboards showing the peer configuration and
-association IDs for all peers, including the radio clock peers. The
-assigned clock address should appear in the pe billboard and the
-association ID for it at the same relative line position in the as
-billboard. If things are operating correctly, after a minute or two
-samples should show up in the pe display line for the clock.
-
-Additional information is available with the rv and clockvar commands,
-which take as argument the association ID shown in the as billboard. The
-rv command with no argument shows the system variables, while the rv
-command with argument shows the peer variables for the clock, as well as
-any other peers of interest. The clockvar command with argument shows
-the peer variables specific to reference clock peers, including the
-clock status, device name, last received timecode (if relevant), and
-various event counters. In addition, a subset of the fudge parameters is
-included.
-
-The xntpdc utility program can be used for detailed inspection of the
-clock driver status. The most useful are the clockstat and clkbug
-commands described in the xntpdc.8 man page. While these commands permit
-getting quite personal with the particular driver involved, their use is
-seldom necessary, unless an implementation bug shows up.
-
-Most drivers write a message to the clockstats file as each timecode or
-surrogate is received from the radio clock. By convention, this is the
-last ASCII timecode (or ASCII gloss of a binary-coded one) received from
-the radio. This file is managed by the filegen facility described in the
-xntpd.8 man page and requires specific commands in the configuration
-file. This forms a highly useful record to discover anomalies during
-regular operation of the clock. The scripts included in the
-./scripts/stats directory can be run from a cron job to collect and
-summarize these data on a daily or weekly basis. The summary files have
-proven invaluable to detect infrequent misbehavior due to clock
-implementation bugs in some radios.
-
-Appendix A. Individual Driver Descriptions
-
-Following are detailed descriptions of the clock drivers, together with
-configuration data useful for special circumstances.
-
-Type 1: Undisciplined Local Clock
-
-     This is a hack to allow a machine to use its own system clock as a
-     reference clock, i.e., to free-run using no outside clock
-     discipline source. This is useful if you want to use NTP in an
-     isolated environment with no radio clock or NIST modem available.
-     Pick a machine that you figure has a good clock oscillator and
-     configure it with this driver. Set the clock using the best means
-     available, like eyeball-and-wristwatch. Then, point all the other
-     machines at this one or use broadcast (not multicast) mode to
-     distribute time.
-
-     Another application for this driver is if you want to use a
-     particular server's clock as the clock of last resort when all
-     other normal synchronization sources have gone away. This is
-     especially useful if that server has an ovenized oscillator. For
-     this you would configure this driver at a higher stratum (say 3 or
-     4) to prevent the server's stratum from falling below that.
-
-     A third application for this driver is when an external discipline
-     source is available, such as the NIST "lockclock" program, which
-     synchronizes the local clock via a telephone modem and the NIST
-     Automated Computer Time Service (ACTS), or the Digital Time
-     Synchronization Service (DTSS), which runs on DCE machines. In this
-     case the stratum should be set at zero, indicating a bona fide
-     stratum-1 source. Exercise some caution with this, since there is
-     no easy way to telegraph via NTP that something might be wrong in
-     the discipline source itself. In the case of DTSS, the local clock
-     can have a rather large jitter, depending on the interval between
-     corrections and the intrinsic frequency error of the clock
-     oscillator. In extreme cases, this can cause clients to exceed the
-     128-ms slew window and drop off the NTP subnet.
-
-     In the default mode the behavior of the clock selection algorithm
-     is modified when this driver is in use. The algorithm is designed
-     so that this driver will never be selected unless no other
-     discipline source is available. This can be overridden with the
-     prefer keyword of the server configuration command, in which case
-     only this driver will be selected for synchronization and all other
-     discipline sources will be ignored. This behavior is intended for
-     use when an external discipline source controls the system clock.
-
-     Fudge Factors
-
-     The stratum for this driver LCLSTRATUM is set at 3 by default, but
-     can be changed by the fudge command and/or the xntpdc utility. The
-     reference ID is "LCL" by default, but can be changed using the same
-     mechanisms. *NEVER* configure this driver to operate at a stratum
-     which might possibly disrupt a client with access to a bona fide
-     primary server, unless the local clock oscillator is reliably
-     disciplined by another source. *NEVER NEVER* configure a server
-     which might devolve to an undisciplined local clock to use
-     multicast mode.
-
-     This driver provides a mechanism to trim the local clock in both
-     time and frequency, as well as a way to manipulate the leap bits.
-     The fudge time1 parameter adjusts the time, in seconds, and the
-     fudge time2 parameter adjusts the frequency, in ppm. Both
-     parameters are additive; that is, they add increments in time or
-     frequency to the present values. (Note: The frequency cannot be
-     changed when the kernel modifications are in use - see the
-     README.kern file). The fudge flag1 and fudge flag2 bits set the
-     corresponding leap bits; for example, setting flag1 causes a leap
-     second to be added at the end of the UTC day. These bits are not
-     reset automatically when the leap takes place; they must be turned
-     off manually after the leap event.
-
-Type 2: TRAK 8820 GPS Receiver
-
-     This driver supports the TRAK 8820 GPS Station Clock. The claimed
-     accuracy at the 1-pps output is 200-300 ns relative to the
-     broadcast signal; however, in most cases the actual accuracy is
-     limited by the precision of the timecode and the latencies of the
-     serial interface and operating system.
-
-     For best accuracy, this radio requires the LDISC_ACTS line
-     discipline, which captures a timestamp at the '*' on-time character
-     of the timecode. Using this discipline the jitter is in the order
-     of 1 ms and systematic error about 0.5 ms. If unavailable, the
-     buffer timestamp is used, which is captured at the \r ending the
-     timecode message. This introduces a systematic error of 23
-     character times, or about 24 ms at 9600 bps, together with a jitter
-     well over 8 ms on Sun IPC-class machines.
-
-     Using the menus, the radio should be set for 9600 bps, one stop bit
-     and no parity. It should be set to operate in computer (no echo)
-     mode. The timecode format includes neither the year nor leap-second
-     warning. No provisions are included in this preliminary version of
-     the driver to read and record detailed internal radio status.
-
-     In operation, this driver sends a RQTS\r request to the radio at
-     initialization in order to put it in continuous time output mode.
-     The radio then sends the following message once each second:
-
-     *RQTS U,ddd:hh:mm:ss.0,q<cr><lf>
-
-     on-time = '*'
-     ddd = day of year
-     hh:mm:ss = hours, minutes, seconds
-     q = quality indicator (phase error), 0-6:
-          0 > 20 us
-          6 > 10 us
-          5 > 1 us
-          4 > 100 ns
-          3 > 10 ns
-          2 < 10 ns
-
-     The alarm condition is indicated by '0' at Q, which means the radio
-     has a phase error than 20 usec relative to the broadcast time. The
-     absence of year, DST and leap-second warning in this format is also
-     alarming.
-
-     The continuous time mode is disabled using the RQTX<cr> request,
-     following which the radio sends a RQTX DONE<cr><lf> response. In
-     the normal mode, other control and status requests are effective,
-     including the leap-second status request RQLS<cr>. The radio
-     responds with RQLS yy,mm,dd<cr><lf>, where yy,mm,dd are the year,
-     month and day. Presumably, this gives the epoch of the next leap
-     second, RQLS 00,00,00 if none is specified in the GPS message.
-     Specified in this form, the information is generally useless and is
-     ignored by the driver.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic.
-
-Type 3: PSTI/Traconex WWV/WWVH Receiver
-
-     This driver supports the PSTI 1010 and Traconex 1020 WWV/WWVH
-     Receivers. No specific claim of accuracy is made for these
-     receiver, but actual experience suggests that 10 ms would be a
-     conservative assumption.
-
-     The DIPswitches should be set for 9600 bps line speed, 24-hour day-
-     of-year format and UTC time zone. Automatic correction for DST
-     should be disabled. It is very important that the year be set
-     correctly in the DIPswitches; otherwise, the day of year will be
-     incorrect after 28 April of a normal or leap year. The propagation
-     delay DIPswitches should be set according to the distance from the
-     transmitter for both WWV and WWVH, as described in the
-     instructions. While the delay can be set only to within 11 ms, the
-     fudge time1 parameter can be used for vernier corrections.
-
-     Using the poll sequence QTQDQM, the response timecode is in three
-     sections totalling 50 ASCII printing characters, as concatenated by
-     the driver, in the following format:
-
-     ahh:mm:ss.fffs<cr> yy/dd/mm/ddd<cr> frdzycchhSSFTttttuuxx<cr>
-
-     on-time = first <cr>
-     hh:mm:ss.fff = hours, minutes, seconds, milliseconds
-     a = AM/PM indicator (' ' for 24-hour mode)
-     yy = year (from DIPswitches)
-     dd/mm/ddd = day of month, month, day of year
-     s = daylight-saving indicator (' ' for 24-hour mode)
-     f = frequency enable (O = all frequencies enabled)
-     r = baud rate (3 = 1200, 6 = 9600)
-     d = features indicator (@ = month/day display enabled)
-     z = time zone (0 = UTC)
-     y = year (5 = 91)
-     cc = WWV propagation delay (52 = 22 ms)
-     hh = WWVH propagation delay (81 = 33 ms)
-     SS = status (80 or 82 = operating correctly)
-     F = current receive frequency (4 = 15 MHz)
-     T = transmitter (C = WWV, H = WWVH)
-     tttt = time since last update (0000 = minutes)
-     uu = flush character (03 = ^c)
-     xx = 94 (unknown)
-
-     The alarm condition is indicated by other than '8' at A, which
-     occurs during initial synchronization and when received signal is
-     lost for an extended period; unlock condition is indicated by other
-     than "0000" in the tttt subfield at Q.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic.
-
-Type 4: Spectracom WWVB Receiver
-
-     This driver supports the Spectracom Model 8170 and Netclock/2 WWVB
-     Synchronized Clock. This clock has proven a reliable source of
-     time, except in some cases of high ambient conductive RF
-     interference. The claimed accuracy of the clock is 100 usec
-     relative to the broadcast signal; however, in most cases the actual
-     accuracy is limited by the precision of the timecode and the
-     latencies of the serial interface and operating system.
-
-     The DIPswitches on this clock should be set to 24-hour display,
-     AUTO DST off, time zone 0 (UTC), data format 0 or 2 (see below) and
-     baud rate 9600. If this clock is to used as the source for the IRIG
-     Audio Decoder (refclock_irig.c in this distribution), set the
-     DIPswitches for AM IRIG output and IRIG format 1 (IRIG B with
-     signature control).
-
-     There are two timecode formats used by these clocks. Format 0,
-     which is available with both the Netclock/2 and 8170, and format 2,
-     which is available only with the Netclock/2 and specially modified
-     8170.
-
-     Format 0 (22 ASCII printing characters):
-
-     <cr><lf>i  ddd hh:mm:ss  TZ=zz<cr><lf>
-
-     on-time = first <cr>
-     hh:mm:ss = hours, minutes, seconds
-     i = synchronization flag (' ' = in synch, '?' = out synch)
-
-     The alarm condition is indicated by other than ' ' at A, which
-     occurs during initial synchronization and when received signal is
-     lost for about ten hours.
-
-     Format 2 (24 ASCII printing characters):
-
-     <cr><lf>iqyy ddd hh:mm:ss.fff ld
-
-     on-time = <cr>
-     i = synchronization flag (' ' = in synch, '?' = out synch)
-     q = quality indicator (' ' = locked, 'A'...'D' = unlocked)
-     yy = year (as broadcast)
-     ddd = day of year
-     hh:mm:ss.fff = hours, minutes, seconds, milliseconds
-
-     The alarm condition is indicated by other than ' ' at A, which
-     occurs during initial synchronization and when received signal is
-     lost for about ten hours. The unlock condition is indicated by
-     other than ' ' at Q.
-
-     The Q is normally ' ' when the time error is less than 1 ms and a
-     character in the set 'A'...'D' when the time error is less than 10,
-     100, 500 and greater than 500 ms respectively. The L is normally '
-     ', but is set to 'L' early in the month of an upcoming UTC leap
-     second and reset to ' ' on the first day of the following month.
-     The D is set to 'S' for standard time 'I' on the day preceding a
-     switch to daylight time, 'D' for daylight time and 'O' on the day
-     preceding a switch to standard time. The start bit of the first
-     <cr> is synchronized to the indicated time as returned.
-
-     This driver does not need to be told which format is in use - it
-     figures out which one from the length of the message. A three-stage
-     median filter is used to reduce jitter and provide a dispersion
-     measure. The driver makes no attempt to correct for the intrinsic
-     jitter of the radio itself, which is a known problem with the older
-     radios.
-
-     Fudge Factors
-
-     This driver can retrieve a table of quality data maintained
-     internally by the Netclock/2 receiver. If flag4 of the fudge
-     configuration command is set to 1, the driver will retrieve this
-     table and write it to the clockstats file on when the first
-     timecode message of a new day is received.
-
-Type 5: TrueTime GPS/GOES Receivers
-
-     This driver supports at least two models of Kinemetrics/TrueTime
-     Timing Receivers, the 468-DC MK III GOES Synchronized Clock and
-     GPS-DC MK III GPS Synchronized Clock and very likely others in the
-     same model family that use the same timecode formats. The clocks
-     are connected via a serial port. Up to four units, with unit
-     numbers in the range 0 through 3, can be configured. The driver
-     assumes the serial port device name is /dev/goes%d (i.e., unit 1 at
-     127.127.5.1 opens the clock at /dev/goes1) and that the clock is
-     configured for 9600-baud operation.
-
-Type 6: IRIG Audio Decoder
-
-     This driver supports the Inter-Range Instrumentation Group standard
-     time-distribution signal IRIG-B using the audio codec native to the
-     Sun SPARCstation. This signal is generated by several radio clocks,
-     including those made by Austron, TrueTime, Odetics and Spectracom,
-     among others, although it is generally an add-on option. The signal
-     is connected via an attenuator box and cable to the audio codec
-     input on a Sun SPARCstation and requires a specially modified
-     kernel audio driver. Details are in the README.irig file.
-
-     Timing jitter using the decoder and a Sun IPC is in the order of a
-     few microseconds, although the overall timing accuracy is limited
-     by the wander of the CPU oscillator used for timing purposes to a
-     few hundred microseconds. These figures are comparable with what
-     can be achieved using the 1-pps discipline as describe elsewhere in
-     this note.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic. The
-     flag3 and flag4 flags are not applicable to this driver.
-
-Type 7: Scratchbuilt CHU Receiver
-
-     This driver supports a shortwave receiver and special modem
-     circuitry described in the ./gadget directory of the xntp3
-     distribution. It requires the chu-clk line discipline or chu_clk
-     STREAMS module described in the ./kernel directory of that
-     distribution. It is connected via a serial port operating at 300
-     baud.
-     Unlike the NIST time services, whose timecode requires quite
-     specialized hardware to interpret, the CHU timecode can be received
-     directly via a serial port after demodulation. While there are
-     currently no known commercial CHU receivers, the hardware required
-     to receive the CHU timecode is fairly simple to build. While it is
-     possible to configure several CHU units simultaneously, this is in
-     general not useful.
-
-     Fudge Factors
-
-     The time1 option can be used to set the CHU propagation delay,
-     compensate for inherent latencies in the serial port hardware and
-     operating system. The default value is 0.0025 seconds, which is
-     about right for Toronto. Values for other locations can be
-     calculated using the propdelay program in the util directory of the
-     xntp3 distribution or equivalent means.
-
-     The time2 option can be used to compensate for inherent latencies
-     in the serial port hardware and operating system. The value, which
-     defaults to zero, is in addition to the propagation delay provided
-     by the time1 option. The default value is 0.0002 seconds, which is
-     about right for typical telephone modem chips.
-
-     The flag1 option can be used to modify the averaging algorithm used
-     to smooth the clock indications. Ordinarily, the algorithm picks
-     the median of a set of samples, which is appropriate under
-     conditions of poor to fair radio propagation conditions. If the
-     clock is located relatively close to the WWV or WWVH transmitters,
-     setting this flag will cause the algorithm to average the set of
-     samples, which can reduce the residual jitter and improve accuracy.
-
-Type 8: Generic Reference Clock Driver
-
-     The timecode of these receivers is sampled via a STREAMS module in
-     the kernel (The STREAMS module has been designed for use with SUN
-     Systems under SunOS 4.1.x. It can be linked directly into the
-     kernel or loaded via the loadable driver mechanism). This STREAMS
-     module can be adapted to be able to convert different time code
-     formats. If the daemon is
-
-     compiled without the STREAM definition synchronization will work
-     without the Sun streams module, though accuracy is significantly
-     degraded.
-
-     The actual receiver status is mapped into various synchronization
-     states generally used by receivers. The STREAMS module is
-     configured to interpret the time codes of DCF U/A 31, PZF535,
-     GPS166, Trimble SV6 GPS, ELV DCF7000, Schmid and low cost receivers
-     (see list below).
-
-     The reference clock support in xntp contains the necessary
-     configuration tables for those receivers. In addition to supporting
-     up to 32 different clock types and 4 devices, the generation a a
-     PPS signal is also provided as an configuration option. The PPS
-     configuration option uses the receiver generated time stamps for
-     feeding the PPS loopfilter control for much finer clock
-     synchronization.
-
-     CAUTION: The PPS configuration option is different from the
-     hardware PPS signal, which is also supported (see below), as it
-     controls the way xntpd is synchronized to the reference clock,
-     while the hardware PPS signal controls the way time offsets are
-     determined.
-
-     The use of the PPS option requires receivers with an accuracy of
-     better than 1ms.
-     Fudge factors
-
-     Only two fudge factors are utilized. The time1 fudge factor defines
-     the phase offset of the synchronization character to the actual
-     time. On the availability of PPS information the time2 fudge factor
-     defines the skew between the PPS time stamp and the receiver
-     timestamp of the PPS signal. This parameter is usually zero, as
-     usually the PPS signal is believed in time and OS delays should be
-     corrected in the machine specific section of the kernel driver.
-     time2 needs only be set when the actual PPS signal is delayed for
-     some reason. The flag0 enables input filtering. This a median
-     filter with continuous sampling. The flag1 selects averaging of the
-     samples remaining after the filtering. Leap secondhandling is
-     controlled with the flag2. When set a leap second will be deleted
-     on receipt of a leap second indication from the receiver. Otherwise
-     the leap second will be added, (which is the default).
-
-     ntpq (8)
-
-     timecode variable
-
-     The ntpq program can read clock variables command list several
-     variables. These hold the following information: refclock_time is
-     the local time with the offset to UTC (format HHMM). The currently
-     active receiver flags are listed in refclock_status. Additional
-     feature flags of the receiver are optionally listed in parentheses.
-     The actual time code is listed in timecode. A qualification of the
-     decoded time code format is following in refclock_format. The last
-     piece of information is the overall running time and the
-     accumulated times for the clock event states in refclock_states.
-     When PPS information is present additional variable are available.
-     refclock_ppstime lists then the PPS timestamp and refclock_ppsskew
-     lists the difference between RS232 derived timestamp and the PPS
-     timestamp.
-
-     Unit encoding
-
-     The unit field <u> encodes the device, clock type and the PPS
-     generation option. There are 4 possible units, which are encoded in
-     the lower two bits of the <u> field. The devices are named
-     /dev/refclock-0 through /dev/refclock-3. Bits 2 thru 6 encode the
-     clock type. The fudge factors of the clock type are taken from a
-     table clockinfo in refclock_parse.c. The generation of PPS
-     information for disciplining the local NTP clock is encoded in bit
-     7 of <u>.
-
-     Currently, nine clock types (devices /dev/refclock-0 -
-     /dev/refclock-3) are supported.

-
-     RAW DCF77 100/200ms pulses (Boeder DCF77 receiver / 5ms)
-
-     The reference clock support carefully monitors the state
-     transitions of the receiver. All state changes and exceptional
-     events such as loss of time code transmission are logged via the
-     syslog facility. Every hour a summary of the accumulated times for
-     the clock states is listed via syslog.
-
-     PPS support is only available when the receiver is completely
-     synchronized. The receiver is believed to deliver correct time for
-     an additional period of time after losing synchronizations, unless
-     a disruption in time code transmission is detected (possible power
-     loss). The trust period is dependent on the receiver oscillator and
-     thus a function of clock type. This is one of the parameters in the
-     clockinfo field of the reference clock implementation. This
-     parameter cannot be configured by xntpdc.
-
-     In addition to the PPS loopfilter control a true PPS hardware
-     signal can be applied on Sun Sparc stations via the CPU serial
-     ports on the CD pin. This signal is automatically detected and will
-     be used for offset calculation. The input signal must be the time
-     mark for the following time code. (The edge sensitivity can be
-     selected - look into the appropriate kernel/parsestreams.c for
-     details). Meinberg receivers can be connected by feeding the PPS
-     pulse of the receiver via a 1488 level converter to Pin 8 (CD) of a
-     Sun serial zs\-port.
-
-     There exists a special firmware release for the PZF535 Meinberg
-     receivers. This release (PZFUERL 4.6 (or higher - The UERL is
-     important)) is absolutely recommended for XNTP use, as it provides
-     LEAP warning, time code time zone information and alternate antenna
-     indication. Please check with Meinberg for this firmware release.
-     For the Meinberg GPS166 receiver is also a special firmware release
-     available (Uni-Erlangen). This release must be used for proper
-     operation.
-
-     The raw DCF77 pulses can be fed via a level converter directly into
-     Pin 3 (Rx) of the Sun. The telegrams will be decoded an used for
-     synchronization. AM DCF77 receivers are running as low as $25. The
-     accuracy is dependent on the receiver and is somewhere between 2ms
-     (expensive) to 10ms (cheap). Upon bad signal reception of DCF77
-     synchronizations will cease as no backup oscillator is available as
-     usually found in other reference clock receivers. So it is
-     important to have a good place for the DCF77 antenna. For
-     transmitter shutdowns you are out of luck unless you have other NTP
-     servers with alternate time sources available.

-Type 9: Magnavox MX4200 GPS Receiver
-
-     This driver supports the Magnavox MX4200 Navigation Receiver
-     adapted to precision timing applications. This requires an
-     interface box described in the ./ppsclock directory of the xntp3
-     distribution. It is connected via a serial port and requires the
-     ppsclock STREAMS module described in the same directory.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic.
-
-Type 10: Austron 2201A GPS Receiver
-
-     This driver supports the Austron 2200A/2201A GPS/LORAN Synchronized
-     Clock and Timing Receiver connected via a serial port. It supports
-     several special features of the clock, including the Input Buffer
-     Module, Output Buffer Module, IRIG-B Interface Module and LORAN
-     Assist Module. It requires the RS232 Serial Interface module for
-     communication with the driver.
-
-     This receiver is capable of a comprehensive and large volume of
-     statistics and operational data. The specific data collection
-     commands and attributes are embedded in the driver source code;
-     however, the collection process can be enabled or disabled using
-     the flag4 flag. If set, collection is enabled; if not, which is the
-     default, it is disabled. A comprehensive suite of data reduction
-     and summary scripts is in the ./scripts/stats directory of the
-     xntp3 distribution.
-
-     To achieve the high accuracy this device provides, it is necessary
-     to use the ppsclock feature of the xntp3 program distribution or,
-     alternatively, to install the kernel modifications described in the
-     README.kern. The clock can be wired to provide time to a single CPU
-     or bussed in parallel to several CPUs, with one CPU controlling the
-     receiver and the others just listening. Fair accuracy can be
-     achieved in the single-CPU configuration without use of the 1-pps
-     signal, but in multiple CPU configurations accuracy is severely
-     degraded without it.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic.
-
-Type 11: TrueTime OM-DC OMEGA Receiver
-
-     This driver supports the Kinemetrics/TrueTime OMEGA-DC OMEGA
-     Synchronized Clock connected via a serial port. This clock is
-     sufficiently different from other Kinemetrics/TrueTime models that
-     a separate driver is required. Up to four units, with unit numbers
-     in the range 0 through 3, can be configured. The driver assumes the
-     serial port device name is /dev/omega%d (i.e., unit 1 at
-     127.127.11.1 opens the clock at /dev/omega1) and that the clock is
-     configured for 9600-baud operation.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic.
-
-Type 12: KSI/Odetics TPRO/S IRIG Interface
-
-     This driver supports the KSI/Odetics TPRO and TPRO-SAT IRIG-B
-     Decoder, which is a module connected directly to the SBus of a Sun
-     workstation. The module works with the IRIG-B signal generated by
-     several radio clocks, including those made by Austron, TrueTime,
-     Odetics and Spectracom, among others, although it is generally an
-     add-on option. In the case of the TPRO-SAT, the module is an
-     integral part of a GPS receiver, which serves as the primary timing
-     source.
-
-     Using the TPRO interface as a NTP reference clock provides
-     precision time only to xntpd and its clients. With suitable kernel
-     modifications, it is possible to use the TPRO as the CPU system
-     clock, avoiding errors introduced by the CPU clock oscillator
-     wander. See the README.kernel and kern.c files for further details.

-Type 13: Leitch CSD 5300 Master Clock Controller
-
-     Information not available.
-
-Type 14: EES M201 MSF Receiver
-
-     This driver supports the EES M201 MSF receiver connected to a Sun
-     SPARCstation running SunOS 4.x with the "ppsclock" STREAMS module.
-
-     Fudge Factors
-
-     If flag1 is set, then the system clock is assumed to be sloppy
-     (e.g. Sun4 with 20ms clock), so samples are averaged. If flag2 is
-     set, then leaphold is set. If flag3 is set, then the sample
-     information is dumped. If flag4 is set, then the input data is
-     smoothed, and all data points are used.

-
-Type 18: NIST Automated Computer Time Service
-
-     This driver supports the NIST Automated Computer Time Service
-     (ACTS). It periodically dials a prespecified telephone number,
-     receives the NIST timecode data and calculates the local clock
-     correction. It designed primarily for use when neither a radio
-     clock nor connectivity to Internet time servers is available. For
-     the best accuracy, the individual telephone line/modem delay needs
-     to be calibrated using outside sources.
-
-     The ACTS is located at NIST Boulder, CO, telephone 303 494 4774. A
-     toll call from Newark, DE, costs between three and four cents,
-     although it is not clear what carrier and time of day discounts
-     apply. The modem dial string will differ depending on local
-     telephone configuration, etc., and is specified by the phone
-     command in the configuration file. The argument to this command is
-     an AT command for a Hayes compatible modem.
-
-     The accuracy produced by this driver should be in the range of a
-     millisecond or two, but may need correction due to the delay
-     characteristics of the individual modem involved. For undetermined
-     reasons, some modems work with the ACTS echo-delay measurement
-     scheme and some don't. This driver tries to do the best it can with
-     what it gets. Initial experiments with a Practical Peripherals
-     9600SA modem here in Delaware suggest an accuracy of a millisecond
-     or two can be achieved without the scheme by using a fudge time1
-     value of 65.0 ms. In either case, the dispersion for a single call
-     involving ten samples is about 1.3 ms.
-
-     The driver can operate in either of three modes, as determined by
-     the mode parameter in the server configuration command. In mode 0
-     (automatic) the driver operates continuously at intervals depending
-     on the prediction error, as measured by the driver, usually in the
-     order of several hours. In mode 1 (backup) the driver is enabled in
-     automatic mode only when no other source of synchronization is
-     available and when more than MAXOUTAGE (3600 s) have elapsed since
-     last synchronized by other sources. In mode 2 (manual) the driver
-     operates only when enabled using a fudge flags switch, as described
-     below.
-
-     For reliable call management, this driver requires a 1200-bps modem
-     with a Hayes-compatible command set and control over the modem data
-     terminal ready (DTR) control line. Present restrictions require the
-     use of a POSIX-compatible programming interface, although other
-     interfaces may work as well. The ACTS telephone number and modem
-     setup string are hard-coded in the driver and may require changes
-     for nonstandard modems or special circumstances.
-
-     Fudge Factors
-
-     Ordinarily, the propagation time correction is computed
-     automatically by ACTS and the driver. When this is not possible or
-     erratic due to individual modem characteristics, the fudge flag2
-     switch should be set to disable the ACTS echo-delay scheme. In any
-     case, the fudge time1 parameter can be used to adjust the
-     propagation delay as required.
-
-     The ACTS call interval is determined in one of three ways. In
-     manual mode a call is initiated by setting fudge flag1 using
-     xntpdc, either manually or via a cron job. In automatic mode this
-     flag is set by the peer timer, which is controlled by the sys_poll
-     variable in response to measured errors. In backup mode the driver
-     is ordinarily asleep, but awakes (in automatic mode) if all other
-     synchronization sources are lost. In either automatic or backup
-     modes, the call interval increases as long as the measured errors
-     do not exceed the value of the fudge time2 parameter.
-
-     When the fudge flag1 is set, the ACTS calling program is activated.
-     This program dials each number listed in the phones command of the
-     configuration file in turn. If a call attempt fails, the next
-     number in the list is dialed. The fudge flag1 and counter are reset
-     and the calling program terminated if (a) a valid clock update has
-     been determined, (b) no more numbers remain in the list, (c) a
-     device fault or timeout occurs, or (d) fudge flag1 is reset
-     manually using xntpdc.
-
-     The NIST timecode message is transmitted at 1200 bps in the
-     following format (see the driver source for more information):
-
-     jjjjj yy-mm-dd hh:mm:ss tt l uuu mmmmm UTC(NIST) *
-
-     jjjjj = modified Julian day
-     yy-mm-dd = year, month, day
-     hh:mm:ss = hours, minutes, seconds
-     tt = DST indicator (see driver listing)
-     l = leap-second warning (see driver listing)
-     uuu = DUT1 correction (see driver listing)
-     mmmmm = modem calibration (see driver listing)
-     on-time = '*'
-
-     The timecode message is transmitted continuously after a signon
-     banner, which this driver ignores. The driver also ignores all but
-     the yy-mm-dd, hh:mm:ss and on-time character '*' fields, although
-     it checks the format of all fields of the message. A timestamp is
-     captured at the '*' character, as required by the ACTS
-     specification, and used as the reference time of the timecode. If a
-     message with an on-time character of '#' is received, the driver
-     updates the propagation delay. The driver disconnects when (a) ten
-     valid messages have been received, (b) no message has been received
-     for 15 s, (c) an on-time character of '#' is received. These
-     messages are processed by a trimmed-mean filter to reduce timing
-     noise and then by the usual NTP algorithms to develop the clock
-     correction.
-
-     The behavior of the clock selection algorithm is modified when this
-     driver is in use. The algorithm is designed so that this driver
-     will never be selected unless no other discipline source is
-     available. This can be overridden with the prefer keyword of the
-     server configuration command, in which case only this driver will
-     be selected for synchronization and all other discipline sources
-     will be ignored. Ordinarily, the prefer keyword would be used only
-     in automatic mode ehen primary time is to be obtained via ACTS and
-     backup NTP peers used only when ACTS fails.
-
-     Call Management
-
-     Since ACTS will be a toll call in most areas of the country, it is
-     necessary to carefully manage the calling interval. The ACTS call
-     program is initiated by setting fudge flag1. This flag can be set
-     manually using xntpdc, by a cron job that calls xntpdc, or
-     automatically by the driver itself. The fudge flag1 is reset when
-     the program terminates after a time determination is comlete or
-     when no more numbers remain in the alternate path list, a device
-     fault or timeout has occured, or the fudge flag1 has been reset
-     using xntpdc.
-
-     In automatic and backup modes, the driver determines the call
-     interval using a procedure depending on the measured prediction
-     error and the fudge time2 parameter. If the error exceeds time2 for
-     a number of times depending on the current interval, the interval
-     is decreased, but not less than about 1000 s. If the error is less
-     than time2 for some number of times, the interval is increased, but
-     not more than about 18 h. With the default value of zero for fudge
-     time2, the interval will increase from 1000 s to the 4000-8000-s
-     range, in which the expected accuracy should be in the 1-2-ms
-     range. Setting fudge time2 to a large value, like 0.1 s, may result
-     in errors of that order, but increase the call interval to the
-     maximum. The exact value for each configuration will depend on the
-     modem and operating system involved, so some experimentation may be
-     necessary.
-
-     Manual call attempts can be made at any time by setting fudge flag1
-     using xntpdc. For example, the xntpdc command
-
-     fudge 127.127.18.1 flags 1
-
-     will ask for a key identifier and password and, if authenticated by
-     the server, will set flag1. There may be a short delay until the
-     expiration of the current poll timeout.
-
-     The flag1 can be set from a cron job in the following way.
-     Construct a file with contents
-
-     keyid 11
-     passwd dialup
-     fudge 127.127.18.1 flags 1
-     quit
-
-     Then, run the following program at specified times as required.
-
-     /usr/local/bin/xntpdc <file
-
-Type 19: Heath WWV/WWVH Receiver
-
-     This driver supports the Heath GC-1000 Most Accurate Clock, with
-     RS232C Output Accessory. This is a WWV/WWVH receiver somewhat less
-     robust than other supported receivers. Its claimed accuracy is 100
-     ms when actually synchronized to the broadcast signal, but this
-     doesn't happen even most of the time, due to propagation
-     conditions, ambient noise sources, etc. When not synchronized, the
-     accuracy is at the whim of the internal clock oscillator, which can
-     wander into the sunset without warning. Since the indicated
-     precision is 100 ms, expect a host synchronized only to this thing
-     to wander to and fro, occasionally being rudely stepped when the
-     offset exceeds the default CLOCK_MAX of 128 ms.
-
-     The internal DIPswitches should be set to operate at 1200 baud in
-     MANUAL mode and the current year. The external DIPswitches should
-     be set to GMT and 24-hour format. It is very important that the
-     year be set correctly in the DIPswitches. Otherwise, the day of
-     year will be incorrect after 28 April of a normal or leap year.
-
-     In MANUAL mode the clock responds to a rising edge of the request
-     to send (RTS) modem control line by sending the timecode.
-     Therefore, it is necessary that the operating system implement the
-     TIOCMBIC and TIOCMBIS ioctl system calls and TIOCM_RTS control bit.
-     Present restrictions require the use of a POSIX-compatible
-     programming interface, although other interfaces may work as well.
-
-     The clock message consists of 23 ASCII printing characters in the
-     following format:
-
-     hh:mm:ss.f     dd/mm/yr<cr>
-
-     hh:mm:ss.f = hours, minutes, seconds
-     f = deciseconds ('?' when out of spec)
-     dd/mm/yr = day, month, year
-
-     The alarm condition is indicated by '?', rather than a digit, at A.
-     Note that 0?:??:??.? is displayed before synchronization is first
-     established and hh:mm:ss.? once synchronization is established and
-     then lost again for about a day.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic. A fudge
-     time1 value of .07 s appears to center the clock offset residuals.

-Type 20: Generic NMEA GPS Receiver
-
-     Information not available.
-
-Type 21: Motorola Six Gun GPS Receiver
-
-     Information not available.
-
-Type 22: PPS Clock Discipline
-
-     This driver furnishes an interface for pulse-per-second (PPS)
-     signals produced by a cesium clock, timing receiver or related
-     equipment. It can be used to remove accumulated jitter and retime a
-     secondary server when synchronized to a primary server over a
-     congested, wide-area network and before redistributing the time to
-     local clients. Note that this driver does not control the system
-     clock if the kernel modifications described in the README.kernel
-     file have been installed, but it can be useful as a monitoring
-     tool.
-
-     In order for this driver to work, the local clock must be set to
-     within +-500 ms by another means, such as a radio clock or NTP
-     itself. The 1-pps signal is connected via a serial port and gadget
-     box consisting of a one-shot and RS232 level converter. When
-     operated at 38.4 kbps with a SPARCstation IPC, this arrangement has
-     a worst-case jitter less than 26 us.
-
-     There are three ways in which this driver can be used. The first
-     way uses the LDISC_PPS line discipline and works only for the
-     baseboard serial ports of the Sun SPARCstation. The PPS signal is
-     connected via a gadget box to the carrier detect (CD) line of a
-     serial port and flag3 of the driver configured for that port is
-     set. This causes the ppsclock streams module to be configured for
-     that port and capture a timestamp at the on-time transition of the
-     PPS signal. This driver then reads the timestamp directly by a
-     designated ioctl() system call. This provides the most accurate
-     time and least jitter of any other scheme. There is no need to
-     configure a dedicated device for this purpose, which ordinarily is
-     the device used for the associated radio clock.
-
-     The second way uses the LDISC_CLKPPS line discipline and works for
-     any architecture supporting a serial port. If after a few seconds
-     this driver finds no ppsclock module configured, it attempts to
-     open a serial port device /dev/pps%d, where %d is the unit number,
-     and assign the LDISC_CLKPPS line discipline to it. If the line
-     discipline fails, no harm is done except the accuracy is reduced
-     somewhat. The pulse generator in the gadget box is adjusted to
-     produce a start bit of length 26 us at 38400 bps (or 104 us at 9600
-     bps). Used with the LDISC_CLKPPS line discipline, this produces an
-     ASCII DEL character ('\377') followed by a timestamp at each
-     seconds epoch.
-
-     The third way involves an auxiliary radio clock driver which calls
-     the PPS driver with a timestamp captured by that driver. This use
-     is documented in the source code for the driver(s) involved.
-
-     Fudge Factors
-
-     There are no special fudge factors other than the generic and those
-     explicitly defined above. The fudge time1 parameter can be used to
-     compensate for miscellaneous UART and OS delays. Allow about 247 us
-     for uart delays at 38400 bps and about 1 ms for SunOS streams
-     nonsense.
-
-Appendix B. Mitigation Rules
-
-In order to provide robust backup sources, stratum-1 peers are usually
-operated in a diversity configuration, in which the local server
-operates with a number of remote peers in addition with one or more
-radio clocks operating also as local peers. In these configurations the
-suite of algorithms used in NTP to refine the data from each peer
-separately and to select and weight the data from a number of peers can
-be used with the entire ensemble of remote peers and local radios.
-However, Because of small but significant systematic time offsets
-between the peers, it is in general not possible to achieve the lowest
-jitter and highest stability in these configurations. In addition, there
-are a number of special configurations involving auxiliary radio clock
-outputs, telephone backup services and other special cases, so that a
-set of mitigation rules becomes necessary.
-
-The mitigation rules are based on a set of special characteristics of
-the various reference clock drivers configured on the server. For
-instance, it is possible to designate a peer as "preferred," in which
-case, all other things being equal, this peer will be selected for
-synchronization over all other eligible candidates in the clock
-selection procedures. The precise characterization of the prefer peer is
-described below. In addition, when a pulse-per-second (PPS) signal is
-connected via the PPS Clock Discipline Driver (type 22), the
-corresponding peer is called the PPS peer. The manner in which this peer
-operates is described below. When the Undisciplined Local Clock Driver
-(type 1) is configured in the server, this becomes the local-clock peer.
-When the Automated Computer Time Service Driver (type 18) is configured
-in the server, this becomes the ACTS peer. Both the local-clock and ACTS
-peers operates in the manner described in Appendix A. Finally, where
-support is available, the PPS signal may be processed directly by the
-kernel. In the following this will be called the kernel discipline.
-
-The mitigation rules apply in the clock selection procedures following
-the sanity checks, intersection algorithm and clustering algorithm. The
-survivors at this point represent the subset of all peers which can
-provide the most accurate, stable time. In the general case, with no
-designated prefer peer, PPS peer or local-clock peer, the mitigation
-rules require all survivors be averaged according to a weight depending
-on the reciprocal of the dispersion, as provided in the NTP
-specification.
-
-The mitigation rules establish the choice of system peer, which
-determine the stratum, reference identifier and several other system
-variables which are visible to clients of the local server. In addition,
-they establish which source or combination of sources control the local
-clock. In detail, these rules operate as follows:
-
-1.   If there is a prefer peer and it is the local-clock peer or the
-     ACTS peer; or, if there is a prefer peer and the kernel discipline
-     is active, choose the prefer peer as the system peer.
-
-2.   If the above is not the case and there is a PPS peer, then choose
-     it as the system peer and its offset as the system clock offset.
-
-3.   If the above is not the case and there is a prefer peer (not the
-     local-clock or ACTS peer in this case), then choose it as the
-     system peer and its offset as the system clock offset.
-
-4.   If the above is not the case and the peer previously chosen as the
-     system peer is in the surviving population, then choose it as the
-     system peer and average its offset along with the other survivors
-     to determine the system clock offset. This behavior is designed to
-     avoid excess jitter due to "clockhopping," when switching the
-     system peer would not materially improve the time accuracy.
-
-5.   If the above is not the case, then choose the first candidate in
-     the list of survivors ranked in order of synchronization distance
-     and average its offset along with the other survivors to determine
-     the system clock offset. This is the default case and the only case
-     considered in the current NTP specification.
-
-The specific interpretation of the prefer peer and PPS peer require some
-explanation, which is given in following sections.
-
-B.1. Using the prefer Keyword
-
-For the reasons stated previously, a scheme has been implemented in NTP
-to provide an intelligent mitigation between various classes of peers,
-one designed to provide the best quality time without compromising the
-normal operation of the NTP algorithms. This scheme in its present form
-is not an integral component of the NTP specification. but is likely to
-be included in future versions of the specification. The scheme is based
-on the "preferred peer," which is specified by including the  prefer
-keyword with the associated server or peer command in the configuration
-file. This keyword can be used with any peer or server, but is most
-commonly used with a radio clock server.
-
-The prefer scheme works on the set of peers that have survived the
-sanity and intersection algorithms of the clock select procedures.
-Ordinarily, the members of this set can be considered truechimers and
-any one of them could in principle provide correct time; however, due to
-various error contributions, not all can provide the most stable time.
-The job of the clustering algorithm, which is invoked at this point, is
-to select the best subset of the survivors providing the least variance
-in the combined ensemble compared to the variance in each member of the
-subset. The detailed operation of the clustering algorithm, which are
-given in the specification, are not important here, other than to point
-out it operates in rounds, where a survivor, presumably the worst of the
-lot, is discarded in each round until one of several termination
-conditions is met.
-
-In the prefer scheme the clustering algorithm is modified so that the
-prefer peer is never discarded; on the contrary, its potential removal
-becomes a termination condition. If the original algorithm were about to
-toss out the prefer peer, the algorithm terminates right there. The
-prefer peer can still be discarded by the sanity and intersection
-algorithms, of course, but it will always survive the clustering
-algorithm. A preferred peer retains that designation as long as it
-survives the intersection algorithm. If for some reason the prefer peer
-fails to survive the intersection algorithm, either because it was
-declared a falseticker or became unreachable, it loses that designation
-and the clock selection remitigates as described above.
-
-Along with this behavior, the clock select procedures are modified so
-that the combining algorithm is not used when a prefer (or PPS) peer is
-present. Instead, the offset of the prefer (or PPS) peer is used
-exclusively as the synchronization source. In the usual case involving a
-radio clock and a flock of remote stratum-1 peers, and with the radio
-clock designated a prefer peer, the result is that the high quality
-radio time disciplines the server clock as long as the radio itself
-remains operational and with valid time, as determined from the remote
-peers, sanity algorithm and intersection algorithm.
-
-While the model does not forbid it, it does not seem useful to designate
-more than one peer as preferred, since the additional complexities to
-mitigate among them do not seem justified from on the air experience.
-Note that the prefer peer interacts with the PPS peer discussed in
-Appendix C. It also interacts with the Undisciplined Local Clock Driver
-(type 1), as described in Appendix A. See the main text for the
-mitigation rules applying to the general case.
-
-B.2. Using the Pulse-per-Second (PPS) Signal
-
-Most radio clocks are connected using a serial port operating at speeds
-of 9600 bps or lower. The accuracy using typical timecode formats, where
-the on-time epoch is indicated by a designated ASCII character, like
-carriage-return <cr>, is limited to a millisecond at best and a few
-milliseconds in typical cases. However, some radios produce a precision
-pulse-per-second (PPS) signal which can be used to improve the accuracy
-in typical workstation servers to the order of a few tens of
-microseconds. The details of how this can be accomplished are discussed
-in the README.magic file; the following discusses how this signal is
-implemented and configured in a typical working server.
-
-First, it should be pointed out that the PPS signal is inherently
-ambiguous, in that it provides a precise seconds epoch, but does not
-provide a way to number the seconds. In principle and most commonly,
-another source of synchronization, either the timecode from an
-associated radio clock, or even a set of remote peers, is available to
-perform that function. In all cases a specific, configured peer or
-server must be designated as associated with the PPS signal. This is
-done by including the prefer keyword with the associated server or peer
-command in the configuration file. This PPS signal can be associated in
-this way any peer or server, but is most commonly used with the radio
-clock generating the PPS signal.
-
-The PPS signal is processed by a special PPS Clock Discipline Driver
-(type 22) described in Appendix A. That description specifies the
-hardware configurations in which this signal can be connected to the
-server. This driver replaces the former scheme based on conditional
-compilation and the PPS, CLK and PPSCLK compile-time switches.
-Regardless of method, the driver, like all other drivers, is mitigated
-in the manner described for the prefer peer in Appendix B. However, in
-the case of the PPS peer, the behavior is slightly more complex.
-
-First, in order for the PPS peer to be considered at all, its associated
-prefer peer must have survived the sanity and intersection algorithms
-and have been designated the prefer peer. This insures that the radio
-clock hardware is operating correctly and that, presumably, the PPS
-signal is operating correctly as well. Second, the absolute time offset
-from that peer must be less than CLOCK_MAX, the gradual-adjustment
-range, which is ordinarily set at 128 ms, or well within the +-0.5-s
-unambiguous range of the PPS signal itself. Finally, the time offsets
-generated by the PPS peer are propagated via the clock filter to the
-clock selection procedures just like any other peer. Should these pass
-the sanity and intersection algorithms, they will show up along with the
-offsets of the prefer peer itself. Note that, unlike the prefer peer,
-the PPS peer samples are not protected from discard by the clustering
-algorithm. These complicated procedures insure that the PPS offsets
-developed in this way are the most accurate, reliable available for
-synchronization.
-
-A PPS peer retains that designation as long as it survives the
-intersection algorithm; however, like any other clock driver, it runs a
-reachability algortihm on the PPS signal itself. If for some reason the
-signal fails or displays gross errors, the PPS peer will either become
-unreachable or stray out of the survivor population. In this case the
-clock selection remitigates as described above.
-
-Finally, the mitigation procedures described above for the prefer peer
-are modified so that, if the PPS peer survives the clustering algorithm,
-its offset is mitigated over the prefer peer offset; in other words in
-case of ties, the PPS offset wins. See the main text for the mitigation
-rules applying to the general case.
-
-B.3. Using the Kernel Discipline
-
-Code to implement the kernel discipline is a special feature that can be
-incorporated in the kernel of some workstations as described in the
-README.kernel file. The discipline provides for the control of the local
-clock oscillator time and/or frequency by means of an external PPS
-signal interfaced via a modem control lead. As the PPS signal is derived
-from external equipment, cables, etc., which sometimes fail, a good deal
-of error checking is done in the kernel to detect signal failure and
-excessive noise.
-
-In order to operate, the kernel discipline must be enabled and the
-signal must be present and within nominal jitter and wander error
-tolerances. In the NTP daemon the kernel is enabled only when the prefer
-peer is among the survivors of the clustering algorithm, as described
-above. Then, the PPS peer is designated the prefer peer as long as the
-PPS signal is present and operating within tolerances. Under these
-conditions the kernel disregards updates produced by the NTP daemon and
-uses its internal PPS source instead. The kernel maintains a watchdog
-timer for the PPS signal; if the signal has not been heard or is out of
-tolerance for more than some interval, currently two minutes, the kernel
-discipline is declared inoperable and operation continues as if it were
-not present.
-Appendix C. NTP Local Clock Discipline
-
-Implementation of the ACTS driver caused somewhat of a shakeup in the
-NTP local clock model and implementation. The model described in the
-specification RFC-1305 is based on a phase-lock loop (PLL) design, which
-is optimum or near optimum for the update intervals used for NTP peers
-and radio clocks, ordinarily in the range 64-1024 s. However, the ACTS
-driver must operate with update intervals in the range well above 1024
-s, where the performance of the PLL model deteriorates. As suggested by
-Judah Levine of NIST and used in his "lockclock" algorithm, a hybrid
-frequency-lock loop (FLL) gives better performance at the longer update
-intervals up to a maximum depending on the acceptable error bound.
-
-In a series of experiments and simulations, it was verified that the PLL
-model provides better performance in the regime less than about 1000 s,
-while the FLL model provides better performance above that. The
-parameters of each model were optimized by simulation for the lowest
-time and frequency error using data collected on an undisciplined
-computer clock oscillator over a period of about two weeks. The PLL/FLL
-hybrid loop has been implemented in NTP, along with certain other
-refinements described below. While it was designed primarily with ACTS
-in mind, it can be used with any NTP peer or radio clock, should that
-prove useful.
-
-To take advantage of this feature for other than the ACTS driver, where
-it is automatic, note that the default minimum poll interval is 64 s and
-default maximum poll interval 1024 s (for the ACTS driver the default
-minimum is 1024 s and default maximum 16384 s). However, using the
-minpoll and/or maxpoll parameters of the server or peer commands in the
-configuration file, it is possible to set the minimum poll interval as
-low as 16 s and the maximum poll interval as high as 16384 s. Poll
-intervals less than 64 s are useful if an exceptionally quick lock is
-required, like in real-time or portable systems. Poll intervals above
-1024 s, other than ACTS, may be useful to reduce traffic in some
-situations, such as when charges are made on a per-packet basis.
-
-Another modification to the stock NTP local clock discipline is to avoid
-errors due to old data. From a study of the stability characteristics of
-typical computer clock oscillators using both experiment and simulation,
-it was determined that data used to discipline the PLL are not generally
-useful if older than about 1000 s. This corresponds roughly to the knee
-in the Allan variance characteristic measured for a typical workstation
-oscillator. The NTP clock filter algorithm was modified to adjust the
-effective length of the shift register so that samples older than about
-1000 s are not used to determine the filtered offset, delay and
-dispersion values. This design has the useful byproduct that the time to
-acquire lock when first coming up and to declare unreachability is
-independent of the poll interval.
-
-A problem which has recurred on every occasion a leap second has been
-inserted in the UTC timescale is that not all radio clocks detect and
-implement the leap event. As a result, some radios sail right through
-the leap, become confused for periods up to 15 minutes, then reacquire
-lock. In order to cope with this, as well as other occasions where
-atypically large offsets occur, the NTP clock discipline has been
-modified to disregard offsets over 128 ms, unless (a) first coming up,
-(b) first returning to service after a period when unsynchronized, or
-(c) an interval of about 15 minutes has elapsed since the last update
-less than 128 ms was received. In addition, the discipline has been
-modified so that, if the first offset received after coming up is less
-than 128 ms, the local clock is immediately reset to that offset without
-affecting the PLL variables.
-
-It has been the experience of some users that, when first installed in a
-system, the NTP clock discipline fails to reliably lock to other peers
-and servers as configured. The indications are that the daemon locks for
-some period of time, but is unable to stabilize the frequency estimate.
-As the result, the time offsets eventually climb above 128 ms and the
-discipline unlocks again. After the 15-minute timeout, the daemon locks
-again and the cycle repeats. The problem here is that the intrinsic
-frequency error of the local clock exceeds the design capture range of
-the PLL, 100 ppm. This particular limit was selected as a compromise
-between useful maximum error indications and the tolerances found in
-typical computer clock oscillators.
-
-In spite of the tolerance assumed in the NTP specification of 100 ppm,
-the NTP daemon for Unix can operate with an intrinsic frequency error of
-over 380 ppm, depending on the values of tick and tickadj selected by
-the tickadj program. However, with errors that large, the PLL will not
-reliably lock, and the behavior noted above can occur. Formerly, the
-only remedial in cases where this happens waas a somewhat painful manual
-process where the nominal oscillator frequency is measured by some other
-means, such as eyeball-and-wristwatch, and a specific drift file
-(ntp.drift) crafted.
-
-In order to avoid the above problem, the NTP clock discipline has been
-modified to measure the frequency during periods when not locked to
-another server or radio clock. Such periods occur when the time offset
-wanders through and beyond the 128-ms window as described above. When
-synchronization is reestablished, the working frequency used by NTP is
-initialized with the measured value. Since a precise frequency
-determination is not always possible under these chaotic conditions, it
-may take more than one cycle of this type to get the residual error
-below 100 ppm and reliable lock established.

-This file is the original README, and is a little out of date.  It
-is also very specific to UofT, since there was a time when the daemon
-was only run here.
-
-To run this:
-
-(1) Fix your kernel's value of tickadj.  Tickadj sets both the
-    precision with which time slews can be performed and the amount
-    of slew you can do in a given interval.  Xntpd operates by making
-    a bunch of little adjustments.  Make tickadj too large (the default
-    value almost always is) and xntpd will perform poorly since the
-    slews will disappear in the roundoff.  Make tickadj too small
-    and large slews won't complete before the next adjustment is
-    ready.
-
-    To determine a good value of tickadj to use, first determine your
-    kernel's value of hz (50 on a Sun 3, 100 on Sun 4's and vaxes).
-    Divide that number into 500 (i.e. compute 500/hz) and use an
-    integer near there as tickadj (say, 10 on Sun 3's, 5 on Sun 4's
-    and vaxes).  Then adb your kernel and write the new value.  You
-    should probably do both the running kernel and the disk image.
-
-    If your machine doesn't come with adb, or if the kernel is of a
-    non-Berkeley flavour, take a look at the util directory, particularly
-    util/tickadj.
-
-(2) Edit the Config file in this directory.  You *must* tell it whether
-    your machine uses big endian or little endian byte order.  Also,
-    Suns running SunOS 3.x require special consideration, as well as Vaxes
-    running Ultrix 2.0 and compilers which don't understand `signed char'
-    declarations.  When you've got all this worked out, type `make makefiles'
-    to distribute configuration information to Makefiles for individual
-    programs, followed by `make' to compile everything.
-
-(2a) Note that, among other things, two programs were made in the authstuff
-    directory, authcert and authspeed.  The last two are utilities for
-    checking the authentication code.  Type `authcert < certdata'.  If
-    this provokes a massive failure you probably got the byte order wrong
-    in the Config file.  Type `authspeed -n 10000 auth.samplekeys', or
-    something, a couple of times to get a value of authdelay to stick in
-    the configuration file.  The numbers for machines I've tried look like:
-
-	uVax II		0.001450
-	Sun 3/180	0.000620
-	uVax III	0.000515
-	Sun 3/60	0.000455
-	IBM RT Mdl 125	0.000323
-	Sun 3/280	0.000302
-	Sun 4/280	0.000110
-	MIPS M/1000	0.000100
-
-(3) Typing `make install' will nstall xntpd, xntpdc, ntpdate and ntpq.  Watch
-    the install location in the Config file.
-
-(4) If you will be running xntpd (see 4a below for the alternative),
-    configure it (configuration is necessary for all machines now, though
-    this restriction will go away when I get broadcast time fully tested).
-    xntpd reads its configuration from /etc/ntp.conf (by default) and
-    you must tell it which machines it is to get its time from in
-    here.
-
-    Note that NTP operates in a hierarchy.  Machines with radio clocks
-    (which are stratum 1 servers) are at the top of the heap, in that
-    all time originates with them.  The situation with servers locally
-    is in a state of flux.  We currently have one semi-reliable stratum 1
-    server on campus (suzuki.ccie), and maintain three other stratum 2
-    servers which (gently) access other people's off-campus stratum 1
-    servers.  All of these machines are lightly loaded and have good
-    quality clocks, and so will probably do until we get some more stratum 1
-    weight.
-
-    Thus you are probably faced with choosing whether your hosts should
-    be stratum 2 or stratum 3 (or stratum 3 or 4 when suzuki's clock is down).
-    The rule of thumb is to make your best clocks and/or your file servers
-    stratum 2 (or 3) by peering them with the four campus servers, and make
-    lesser clocks and clients stratum 3 (or 4) by peering them with near
-    by servers which are synchonized to the campus servers.  The second rule
-    of thumb is that more servers are better.  It is quite possible to
-    synchronize with just a single server, but if you do your xtnpd daemon
-    won't have any cross checks to tell it when the server has gone
-    wonky. 3 or 4 lower stratum peers is about right.  Note that while
-    you can also peer with same-stratum peers, you shouldn't do this
-    unless the same-stratum peer is exchanging time with a lower stratum
-    peer you don't talk to directly.
-
-    Anyway, for your stratum 2 servers you can probably use ntp.conf
-    from the conf directory directly.  You will have to handcraft the
-    peer assocations for your stratum 3 servers.
-
-    Oh, and a note about the drift file (see ntp.conf).  One of the
-    things xntpd does is accumulate a correction for the frequency of
-    the crystal in your computer.  It usually takes a day or so of
-    running to figure this out, after which the value will usually remain
-    pretty stable, especially if the computer is in a machine room.  The
-    value is printed in your syslog file (once a minute, currently, though
-    this will change), and can be obtained from the daemon using xntpdc.
-
-    To avoid having to wait a day after restarts before the computer
-    synchronizes really well, xntpd will optionally write its current
-    value of the frequency correction into a file, once an hour.  When
-    it is killed and restarted, xntpd reinitializes itself to this
-    value on start up.  This is an advantageous feature, so a driftfile
-    line should always be included in the configuration file.
-
-(4a) Xntpd is a daemon.  It will keep your time exquisitely precise under
-     normal conditions (it is quite capable of keeping a good clock within
-     a millisecond of a good server.  Our servers aren't normally this
-     good, yet, but may become so when we get a few more stable local
-     stratum 1 peers).  Even when cut off entirely from its servers xntpd
-     will prevent your clock from drifting seriously by continuing to apply
-     its accumulated frequency correction.  The cost of this is that xntpd
-     will permanently consume memory while it is running, and real memory
-     at that since xntpd is unlikely to ever swap out.  This cost is
-     currently over 100 kb.
-
-     If you aren't too worried about millisecond timing and feel religious
-     about keeping memory consumption at a minimum (perhaps on memory-poor
-     workstations), a passable alternative might be to run ntpdate instead.
-     Ntpdate is the NTP equivalent of rdate, a one shot date setting
-     program, and implements the same multiple sample/multiple server
-     filter algorithms as xntpd.  Ntpdate was explicitly designed to be
-     run repeatly from cron, though it also makes a good boot time date
-     setter.  Running ntpdate from cron on an hourly basis will keep all
-     but seriously broken clocks within 100 ms of on-time, and for most
-     clocks will probably do better than 50 ms.  If this is an attractive
-     alternative see the manual page.  You should choose ntpdate's servers
-     as you would the peer associations for a stratum 3 xntpd server.
-
-(5) Once everything is configured, start the daemon(s).  ntpq can be
-    used to see what xntpd is doing.  It runs both interactive and from
-    the command line, type ? to see the interactive commands and ? command
-    to see what a command does.  The `peers' command is a good one.  ntpq
-    can also be used to see what other peoples' servers are doing, in
-    particular the fuzzball primary servers.
-
-(6) If you want to use the authentication facility (this might be useful
-    if, for example, you were running Kerberos since this prevents people
-    from setting your time back and doing replay attacks on the server),
-    you might find a couple of useful programs in the auth_stuff directory.
-    mkrandkeys will generate some very random keys to use.  keyparity
-    generates odd parity bits for keys (needed for the key file) and will
-    convert between key formats.
-
-All bug reports gratefully received.

- * This driver supports the NIST Automated Computer Time Service (ACTS).

- * It periodically dials a prespecified telephone number, receives the

- * NIST timecode data and calculates the local clock correction. It is

- * designed primarily for use as a backup when neither a radio clock nor

- * connectivity to Internet time servers is available. For the best

- * accuracy, the individual telephone line/modem delay needs to be

- * calibrated using outside sources.

- *

- * The ACTS is located at NIST Boulder, CO, telephone 303 494 4774. A

- * toll call from a residence telephone in Newark, DE, costs between 14

- * and 27 cents, depending on time of day, and from a campus telephone

- * between 3 and 4 cents, although it is not clear what carrier and time

- * of day discounts apply in this case. The modem dial string will

- * differ depending on local telephone configuration, etc., and is

- * specified by the phone command in the configuration file. The

- * argument to this command is an AT command for a Hayes compatible

- * modem.

- *

- * The accuracy produced by this driver should be in the range of a

- * millisecond or two, but may need correction due to the delay

- * characteristics of the individual modem involved. For undetermined

- * reasons, some modems work with the ACTS echo-delay measurement scheme

- * and some don't. This driver tries to do the best it can with what it

- * gets. Initial experiments with a Practical Peripherals 9600SA modem

- * here in Delaware suggest an accuracy of a millisecond or two can be

- * achieved without the scheme by using a fudge time1 value of 65.0 ms.

- * In either case, the dispersion for a single call involving ten

- * samples is about 1.3 ms.

- *

- * The driver can operate in either of two modes, as determined by the

- * mode parameter in the server configuration command. In mode 0 the

- * driver operates continuously at intervals determined by the fudge

- * time1 parameter, as described above. In mode 1 the driver is enabled

- * only when no other sources of synchronization are available and when

- * we have gone more than MAXOUTAGE (3600 s) since last synchronized by

- * other sources of synchronization.

- *

- * For reliable call management, this driver requires a 1200-bps modem

- * with a Hayes-compatible command set and control over the modem data

- * terminal ready (DTR) control line. Present restrictions require the

- * use of a POSIX-compatible programming interface, although other

- * interfaces may work as well. The modem setup string is hard-coded in

- * the driver and may require changes for nonstandard modems or special

- * circumstances.

- *

- * Further information can be found in the README.refclock file in the

- * xntp3 distribution.

- *

- * Fudge Factors

- *

- * Ordinarily, the propagation time correction is computed automatically

- * by ACTS and the driver. When this is not possible or erratic due to

- * individual modem characteristics, the fudge flag2 switch should be

- * set to disable the ACTS echo-delay scheme. In any case, the fudge

- * time1 parameter can be used to adjust the propagation delay as

- * required.

- *

- * The ACTS call interval is determined in one of three ways. In MANUAL

- * mode a call is initiated by setting fudge flag1 using xntpdc, either

- * manually or via a cron job. In AUTO mode this flag is set by the peer

- * timer, which is controlled by the sys_poll variable in response to

- * measured errors. In BACKUP mode the driver is ordinarily asleep, but

- * awakes (in AUTO mode) if all other synchronization sources are lost.

- * In either AUTO or BACKUP modes, the call interval increases as long

- * as the measured errors do not exceed the value of the fudge time2

- * parameter.

- *

- * When the fudge flag1 is set, the ACTS calling program is activated.

- * This program dials each number listed in the phones command of the

- * configuration file in turn. If a call attempt fails, the next number

- * in the list is dialed. The fudge flag1 and counter are reset and the

- * calling program terminated if (a) a valid clock update has been

- * determined, (b) no more numbers remain in the list, (c) a device

- * fault or timeout occurs or (d) fudge flag1 is reset manually using

- * xntpdc.

- * DST	Daylight savings time characters, valid for the continental

- *	U.S., are set as follows:

- *

- *	00	We are on standard time (ST).

- *	01-49	Now on DST, go to ST when your local time is 2:00 am and

- *

- *	The two DST characters provide up to 48 days advance notice of a

- *

- * LS	Leap second flag is set to "1" to indicate that a leap second is

- *	to be added as 23:59:60 (UTC) on the last day of the current UTC

- *	month. The LS flag will be reset to "0" starting with 23:59:60

- *	(UTC). The flag will remain on for the entire month before the

- *	second is added. Leap seconds are added as needed at the end of

- *	any month. Usually June and/or December are chosen.

- * Maximum on line time will be 56 seconds. If all lines are busy at any

- * time, the oldest call will be terminated if it has been on line more

- * than 28 seconds, otherwise, the call that first reaches 28 seconds

- * will be terminated.

- *

- * Current time is valid at the "on-time" marker (OTM), either "*" or

- * "#". The nominal on-time marker (*) will be transmitted 45 ms early

- * to account for the 8 ms required to send 1 character at 1200 Baud,

- * plus an additional 7 ms for delay from NIST to the user, and

- * approximately 30 ms "scrambler" delay inherent in 1200 Baud modems.

- * If the caller echoes all characters, NIST will measure the round trip

- * delay and advance the on-time marker so that the midpoint of the stop

- * bit arrives at the user on time. The amount of msADV will reflect the

- * actual required advance in milliseconds and the OTM will be a "#".

- *

- * (The NIST system requires 4 or 5 consecutive delay measurements which

- * are consistent before switching from "*" to "#". If the user has a

- * 1200 Baud modem with the same internal delay as that used by NIST,

- * then the "#" OTM should arrive at the user within +-2 ms of the

- * correct time. 

- *

- * However, NIST has studied different brands of 1200 Baud modems and

- * found internal delays from 24 ms to 40 ms and offsets of the "#" OTM

-Introduction
-
-This document is a collection of notes concerning the use of xntpd and
-related programs, and on coping with the Network Time Protocol (NTP) in
-general. It is a major rewrite and update of an earlier document written
-by Dennis Ferguson of the University of Toronto dated 5 November 1989.
-It includes many changes and additions resulting from the NTP Version 3
-specification and new implementation features. It supersedes the earlier
-document, which should no longer be used for new configurations.
-
-Xntpd is a complete implementation of the NTP Version 3 specification as
-defined in RFC 1305. It also retains compatibility with both NTP Version
-2, as defined in RFC 1119, and NTP Version 1, as defined in RFC 1059,
-although this compatibility is sometimes strained and only
-semiautomatic. In order to support in principle the ultimate precision
-of about 232 picoseconds in the NTP specification, xntpd does no
-floating-point arithmetic and instead manipulates the 64-bit NTP
-timestamps as unsigned 64-bit integers. Xntpd fully implements NTP
-Versions 2 and 3 authentication and a mode-6 control-message facility.
-As extensions to the specification, a flexible address-and-mask
-restriction facility has been included, along with a private mode-7
-control-message facility used to remotely reconfigure the system and
-monitor a considerable amount of internal detail.
-
-The code is biased towards the needs of a busy time server with
-numerous, possibly hundreds, of clients and other servers. Tables are
-hashed to allow efficient handling of many associations, though at the
-expense of additional overhead when the number of associations is small.
-Many fancy features have been included to permit efficient management
-and monitoring of a busy primary server, features which are simply
-excess baggage for a server on a high stratum client. The code was
-written with near demonic attention to details which can affect
-precision and as a consequence should be able to make good use of high
-performance, special purpose hardware such as precision oscillators and
-radio clocks. The present code supports a number of radio clocks,
-including those for the WWV, CHU, WWVB, DCF77, GOES and GPS radio and
-satellite services. The server methodically avoids the use of Unix-
-specific library routines where possible by implementing local versions,
-in order to aid in porting the code to perverse Unix and non-Unix
-platforms.
-
-While this implementation slavishly obeys the NTP specification RFC
-1305, it has been specifically tuned to achieve the highest accuracy
-possible on whatever hardware and operating-system platform is
-available. In general, its precision is limited only by that of the
-onboard time-of-day clock maintained by the hardware and operating
-system, while its stability is limited only by that of the onboard
-frequency source, usually an uncompensated crystal oscillator. On modern
-RISC-based processors connected directly to radio clocks via serial-
-asynchronous interfaces, the accuracy is usually limited by that of the
-radio clock and interface to the order of a few milliseconds. The code
-includes special features to support a one-pulse-per-second (1-pps)
-signal generated by some radio clocks. When used in conjunction with a
-suitable hardware level converter, the accuracy can be improved to the
-order of 100 microseconds. Further improvement is possible using an
-outboard, stabilized frequency source, in which the accuracy and
-stability are limited only by the characteristics of that source.
-
-The xntp3 distribution includes, in addition to the daemon itself
-(xntpd), several utility programs, including two remote-monitoring
-programs (ntpq, xntpdc), a remote clock-setting program similar to the
-Unix rdate program (ntpdate), a traceback utility useful to discover
-suitable synchronization sources (ntptrace), and various programs used
-to configure the local platform and calibrate the intrinsic errors. NTP
-has been ported to a large number of platforms, including most RISC and
-CISC workstations and mainframes manufactured today. Example
-configuration files for many models of these machines are included in
-the xntp3 distribution. While in most cases the standard version of the
-implementation runs with no hardware or operating-system modifications,
-not all features of the distribution are available on all platforms. For
-instance, a special feature allowing Sun 4s to achieve accuracies in the
-order of 100 microseconds requires some minor changes and additions to
-the kernel and input/output support.
-
-There are, however, several drawbacks to all of this. Xntpd is very,
-very fat. This is rotten if your intended platform for the daemon is
-memory-limited. Xntpd uses SIGIO for all input, a facility which appears
-to not enjoy universal support and whose use seems to exercise the parts
-of your vendors' kernels which are most likely to have been done poorly.
-The code is unforgiving in the face of kernel problems which affect
-performance, and generally requires that you repair the problems in
-order to achieve acceptable performance. The code has a distinctly
-experimental flavour and contains features which could charitably be
-termed failed experiments, but which have not been hacked out yet. There
-is code which has not been thoroughly tested (e.g. leap-second support)
-due to the inconvenience of setting up tests. Much was learned from the
-addition of support for a variety of radio clocks, with the result that
-this support could use some rewriting.
-
-How NTP Works
-
-The approach used by NTP to achieve reliable time synchronization from a
-set of possibly unreliable remote time servers is somewhat different
-than other such protocols. In particular, NTP does not attempt to
-synchronize clocks to each other. Rather, each server attempts to
-synchronize to UTC (i.e., Universal Coordinated Time) using the best
-available source and available transmission paths to that source. This
-is a fine point which is worth understanding. A group of NTP-
-synchronized clocks may be close to each other in time, but this is not
-a consequence of the clocks in the group having synchronized to each
-other, but rather because each clock has synchronized closely to UTC via
-the best source it has access to. As such, trying to synchronize a set
-of clocks to a set of servers whose time is not in mutual agreement may
-not result in any sort of useful synchronization of the clocks, even if
-you don't care about UTC. NTP operates on the premise that there is one
-true standard time, and that if several servers which claim
-synchronization to standard time disagree about what that time is, then
-one or more of them must be broken. There is no attempt to resolve
-differences more gracefully since the premise is that substantial
-differences cannot exist. In essence, NTP expects that the time being
-distributed from the root of the synchronization subnet will be derived
-from some external source of UTC (e.g. a radio clock). This makes it
-somewhat inconvenient (though not impossible) to synchronize hosts
-together without a reliable source of UTC to synchronize them to. If
-your network is isolated and you cannot access other people's servers
-across the Internet, a radio clock may make a good investment.
-
-Time is distributed through a hierarchy of NTP servers, with each server
-adopting a "stratum" which indicates how far away from an external
-source of UTC it is operating at. Stratum-1 servers, which are at the
-top of the pile (or bottom, depending on your point of view), have
-access to some external time source, usually a radio clock synchronized
-to time signal broadcasts from radio stations which explicitly provide a
-standard time service. A stratum-2 server is one which is currently
-obtaining time from a stratum-1 server, a stratum-3 server gets its time
-from a stratum-2 server, and so on. To avoid long lived synchronization
-loops the number of strata is limited to 15.
-
-Each client in the synchronization subnet (which may also be a server
-for other, higher stratum clients) chooses exactly one of the available
-servers to synchronize to, usually from among the lowest stratum servers
-it has access to. It is thus possible to construct a synchronization
-subnet where each server has exactly one source of lower stratum time to
-synchronize to. This is, however, not an optimal configuration, for
-indeed NTP operates under another premise as well, that each server's
-time should be viewed with a certain amount of distrust. NTP really
-prefers to have access to several sources of lower stratum time (at
-least three) since it can then apply an agreement algorithm to detect
-insanity on the part of any one of these. Normally, when all servers are
-in agreement, NTP will choose the best of these, where "best" is defined
-in terms of lowest stratum, closest (in terms of network delay) and
-claimed precision, along with several other considerations. The
-implication is that, while one should aim to provide each client with
-three or more sources of lower stratum time, several of these will only
-be providing backup service and may be of lesser quality in terms of
-network delay and stratum (i.e. a same-stratum peer which receives time
-from lower stratum sources the local server doesn't access directly can
-also provide good backup service).
-
-Finally, there is the issue of association modes. There are a number of
-modes in which NTP servers can associate with each other, with the mode
-of each server in the pair indicating the behaviour the other server can
-expect from it. In particular, when configuring a server to obtain time
-from other servers, there is a choice of two modes which may be
-alternatively used. Configuring an association in symmetric-active mode
-(usually indicated by a "peer" declaration in configuration files)
-indicates to the remote server that one wishes to obtain time from the
-remote server and that one is also willing to supply time to the remote
-server if need be. This mode is appropriate in configurations involving
-a number of redundant time servers interconnected via diverse network
-paths, which is presently the case for most stratum-1 and stratum-2
-servers on the Internet today. Configuring an association in client mode
-(usually indicated by a "server" declaration in configuration files)
-indicates that one wishes to obtain time from the remote server, but that
-one is not willing to provide time to the remote server. This mode is
-appropriate for file-server and workstation clients that do not provide
-synchronization to other local clients. Client mode is also useful for
-boot-date-setting programs and the like, which really have no time to
-provide and which don't retain state about associations over the longer
-term.
-
-Configuring Your Subnet
-
-At startup time the xntpd daemon running on a host reads the initial
-configuration information from a file, usually /etc/ntp.conf, unless a
-different name has been specified at compile time. Putting something in
-this file which will enable the host to obtain time from somewhere else
-is usually the first big hurdle after installation of the software
-itself, which is described in other documents included in the xntp3
-distribution. At its simplest, what you need to do in the configuration
-file is declare the servers that the daemon should poll for time
-synchronization. In principle, no such list is needed if some other time
-server explicitly mentions the host and is willing to provide
-synchronization; however, this is considered dangerous, unless the
-access control or authentication features (described later) are in use.
-
-In the case of a workstation operating in an enterprise network for a
-public or private organization, there is often an administrative
-department that coordinates network services, including NTP. Where
-available, the addresses of appropriate servers can be provided by that
-department. However, if this infrastructure is not available, it is
-necessary to explore some portion of the existing NTP subnet now running
-in the Internet. There are at present many thousands of time servers
-running NTP in the Internet, a significant number of which are willing
-to provide a public time-synchronization service. Some of these are
-listed in a file maintained on the Internet host louie.udel.edu
-(128.175.1.3) on the path pub/ntp/doc/clock.txt. This file is updated on
-a regular basis using information provided voluntarily by various site
-administrators. There are other ways to explore the nearby subnet using
-the ntptrace and ntpq programs. See the man pages for further
-information on these programs.
-
-It is vital to carefully consider the issues of robustness and
-reliability when selecting the sources of synchronization. Normally, not
-less than three sources should be available, preferably selected to
-avoid common points of failure. It is usually better to choose sources
-which are likely to be "close" to you in terms of network topology,
-though you shouldn't worry overly about this if you are unable to
-determine who is close and who isn't. Normally, it is much more serious
-when a server becomes faulty and delivers incorrect time than when it
-simply stops operating, since an NTP-synchronized host normally can
-coast for hours or even days without its clock accumulating serious
-error over one second, for instance. Selecting at least three sources
-from different operating administrations, where possible, is the minimum
-recommended, although a lesser number could provide acceptable service
-with a degraded degree of robustness.
-
-Normally, it is not considered good practice for a single workstation to
-request synchronization from a primary (stratum-1) time server. At
-present, these servers provide synchronization for hundreds of clients
-in many cases and could, along with the network access paths, become
-seriously overloaded if large numbers of workstation clients requested
-synchronization directly. Therefore, workstations located in sparsely
-populated administrative domains with no local synchronization
-infrastructure should request synchronization from nearby stratum-2
-servers instead. In most cases the keepers of those servers listed in
-the clock.txt file provide unrestricted access without prior permission;
-however, in all cases it is considered polite to notify the
-administrator listed in the file upon commencement of regular service.
-In all cases the access mode and notification requirements listed in the
-file must be respected.
-
-In the case of a gateway or file server providing service to a
-significant number of workstations or file servers in an enterprise
-network it is even more important to provide multiple, redundant sources
-of synchronization and multiple, diversity-routed, network access paths.
-The preferred configuration is at least three administratively
-coordinated time servers providing service throughout the administrative
-domain including campus networks and subnetworks. Each of these should
-obtain service from at least two different outside sources of
-synchronization, preferably via different gateways and access paths.
-These sources should all operate at the same stratum level, which is one
-less than the stratum level to be used by the local time servers
-themselves. In addition, each of these time servers should peer with all
-of the other time servers in the local administrative domain at the
-stratum level used by the local time servers, as well as at least one
-(different) outside source at this level. This configuration results in
-the use of six outside sources at a lower stratum level (toward the
-primary source of synchronization, usually a radio clock), plus three
-outside sources at the same stratum level, for a total of nine outside
-sources of synchronization. While this may seem excessive, the actual
-load on network resources is minimal, since the interval between polling
-messages exchanged between peers usually ratchets back to no more than
-one message every 17 minutes.
-
-The stratum level to be used by the local time servers is an engineering
-choice. As a matter of policy, and in order to reduce the load on the
-primary servers, it is desirable to use the highest stratum consistent
-with reliable, accurate time synchronization throughout the
-administrative domain. In the case of enterprise networks serving
-hundreds or thousands of client file servers and workstations,
-conventional practice is to obtain service from stratum-1 primary
-servers such as listed in the clock.txt file. When choosing sources away
-from the primary sources, the particular synchronization path in use at
-any time can be verified using the ntptrace program included in the
-xntp3 distribution. It is important to avoid loops and possible common
-points of failure when selecting these sources. Note that, while NTP
-detects and rejects loops involving neighboring servers, it does not
-detect loops involving intervening servers. In the unlikely case that
-all primary sources of synchronization are lost throughout the subnet,
-the remaining servers on that subnet can form temporary loops and, if
-the loss continues for an interval of many hours, the servers will drop
-off the subnet and free-run with respect to their internal (disciplined)
-timing sources.
-
-In many cases the purchase of one or more radio clocks is justified, in
-which cases good engineering practice is to use the configurations
-described above and connect the radio clock to one of the local servers.
-This server is then encouraged to participate in a special primary-
-server subnetwork in which each radio-equipped server peers with several
-other similarly equipped servers. In this way the radio-equipped server
-may provide synchronization, as well as receive synchronization, should
-the local or remote radio clock(s) fail or become faulty. Xntpd treats
-attached radio clock(s) in the same way as other servers and applies the
-same criteria and algorithms to the time indications, so can detect when
-the radio fails or becomes faulty and switch to alternate sources of
-synchronization. It is strongly advised, and in practice for most
-primary servers today, to employ the authentication or access-control
-features of the xntp3 distribution in order to protect against hostile
-penetration and possible destabilization of the time service.
-
-Using this or similar strategies, the remaining hosts in the same
-administrative domain can be synchronized to the three (or more)
-selected time servers. Assuming these servers are synchronized directly
-to stratum-1 sources and operate normally as stratum-2, the next level
-away from the primary source of synchronization, for instance various
-campus file servers, will operate at stratum 3 and dependent
-workstations at stratum 4. Engineered correctly, such a subnet will
-survive all but the most exotic failures or even hostile penetrations of
-the various, distributed timekeeping resources.
-
-The above arrangement should provide very good, robust time service with
-a minimum of traffic to distant servers and with manageable loads on the
-local servers. While it is theoretically possible to extend the
-synchronization subnet to even higher strata, this is seldom justified
-and can make the maintenance of configuration files unmanageable.
-Serving time to a higher stratum peer is very inexpensive in terms of
-the load on the lower stratum server if the latter is located on the
-same concatenated LAN. When justified by the accuracy expectations, NTP
-can be operated in broadcast mode, so that clients need only listen for
-periodic broadcasts and do not need to send anything.
-
-When planning your network you might, beyond this, keep in mind a few
-generic don'ts, in particular:
-
-1.   Don't synchronize a local time server to another peer at the same
-     stratum, unless the latter is receiving time from lower stratum
-     sources the former doesn't talk to directly. This minimizes the
-     occurance of common points of failure, but does not eliminate them
-     in cases where the usual chain of associations to the primary
-     sources of synchronization are disrupted due to failures.
-2.   Don't configure peer associations with higher stratum servers. Let
-     the higher strata configure lower stratum servers, but not the
-     reverse. This greatly simplifies configuration file maintenance,
-     since there is usually much greater configuration churn in the high
-     stratum clients such as personal workstations.
-
-3.   Don't synchronize more than one time server in a particular
-     administrative domain to the same time server outside that domain.
-     Such a practice invites common points of failure, as well as raises
-     the possibility of massive abuse, should the configuration file be
-     automatically distributed do a large number of clients.
-
-There are many useful exceptions to these rules. When in doubt, however,
-follow them.
-
-Dennis Ferguson writes: Note that mention was made of machines with
-"good" clocks versus machines with "bad" ones. There are two things that
-make a clock good, the precision of the clock (e.g. how many low order
-bits in a time value are actually significant) and the frequency of
-occurance (or lack thereof) of such things as lost clock interrupts.
-Among the most common computers I have observed there to be a fairly
-simple algorithm for determining the goodness of its clock. If the
-machine is a Vax, it probably has a good clock (the low order bit in the
-time is in the microseconds and most of these seem to manage to get
-along without losing clock interrupts). If the machine is a Sun 3 it
-probably doesn't (the low order clock bit is at the 10 or 20 millisecond
-mark and Sun 3s like to lose clock interrupts, particularly if they have
-a screen and particularly if they run SunOS 4.0.x). If you have IBM RTs
-running AOS 4.3, they have fair clocks (low order clock bit at about a
-millisecond and they don't lose clock interrupts, though they do have
-trouble with clock rollovers while reading the low order clock bits) but
-I recommend them as low stratum NTP servers anyway since they aren't
-much use as anything else. Sun 4s running SunOS 4.1.1 make very good
-time servers, once some native foolishness mentioned below is
-surmounted. [However, it is very important to avoid using the keyboard
-firmware, which can cause severe interrupt latencies, in favor of the
-software drivers ordinarily used in conjunction with a windowing system.
-- DLM] For other machines you are on your own since I don't have enough
-data points to venture an opinion. In any event, if at all possible you
-should try to use machines with good clocks for the lower strata.
-
-Configuring Your Server or Client
-
-As mentioned previously, the configuration file is usually called
-/etc/ntp.conf. This is an ASCII file conforming to the usual comment and
-whitespace conventions. A working configuration file might look like (In
-this and other examples, do not copy this directly.):
-
-     # peer configuration for 128.100.100.7
-     # (expected to operate at stratum 2)
-
-     server 128.4.1.1         # rackety.udel.edu
-     server 128.8.10.1        # umd1.umd.edu
-     server 192.35.82.50      # lilben.tn.cornell.edu
-     driftfile /etc/ntp.drift
-
-This particular host is expected to operate as a client at stratum 2 by
-virtue of the "server" keyward and the fact that two of the three
-servers declared (the first two, actually) have radio clocks and usually
-run at stratum 1. The third server in the list has no radio clock, but
-is known to maintain associations with a number of stratum 1 peers and
-usually operates at stratum 2. Of particular importance with the last
-host is that it maintains associations with peers besides the two
-stratum 1 peers mentioned. This can be verified using the ntpq program
-included in the xntp3 distribution. When configured using the "server"
-keyword, this host can receive synchronization from any of the listed
-servers, but can never provide synchronization to them.
-
-Unless restricted using facilities described later, this host can
-provide synchronization to dependent clients, which do not have to be
-listed in the configuration file. Associations maintained for these
-clients are transitory and result in no persistent state in the host.
-These clients are normally not visible using the ntpq program included
-in the xntp3 distribution; however, xntpd includes a monitoring feature
-(described later) which caches a minimal amount of client information
-useful for debugging administrative purposes.
-
-A time server expected to both receive synchronization from another
-server, as well as to provide synchronization to it, is delared using
-the "peer" keyword instead of the "server" keyword. In all other aspects
-the server operates the same in either mode and can provide
-synchronization to dependent clients or other peers. It is considered
-good engineering practice to declare time servers outside the
-administrative domain as "peer" and those inside as "server" in order to
-provide redundancy in the global Internet, while minimizing the
-possibility of instability within the domain itself. A time server in
-one domain can in principle heal another domain temporarily isolated
-from all other sources of synchronization. However, it is probably
-unwise for a casual workstation to bridge fragments of the local domain
-which have become temporarily isolated.
-
-Note the inclusion of a "driftfile" declaration. One of the things the
-NTP daemon does when it is first started is to compute the error in the
-intrinsic frequency of the clock on the computer it is running on. It
-usually takes about a day or so after the daemon is started to compute a
-good estimate of this (and it needs a good estimate to synchronize
-closely to its server). Once the initial value is computed, it will
-change only by relatively small amounts during the course of continued
-operation. The "driftfile" declaration indicates to the daemon the name
-of a file where it may store the current value of the frequency error so
-that, if the daemon is stopped and restarted, it can reinitialize itself
-to the previous estimate and avoid the day's worth of time it will take
-to recompute the frequency estimate. Since this is a desireable feature,
-a "driftfile" declaration should always be included in the configuration
-file.
-
-An implication in the above is that, should xntpd be stopped for some
-reason, the local platform time will diverge from UTC by an amount that
-depends on the intrinsic error of the clock oscillator and the time
-since last synchronized. In view of the length of time necessary to
-refine the frequency estimate, every effort should be made to operate
-the daemon on a continuous basis and minimize the intervals when for
-some reason it is not running.
-
-Xntpd3 Versus Previous Versions
-
-There are several items of note when dealing with a mixture of xntp3 and
-and previous distributions of xntp (NTP Version 2 xntpd) and ntp3.4 (NTP
-Version 1 ntpd). The xntp3 implementation of xntpd is an NTP Version 3
-implementation. As such, by default when no additional information is
-available concerning the preferences of the peer, xntpd claims to be
-version 3 in the packets that it sends.
-
-An NTP implementation conforming to a previous version specification
-ordinarily discards packets from a later version. However, in most
-respects documented in RFC 1305, the previous version is compatible with
-the version-3 algorithms and protocol. Ntpd, while implementing most of
-the version-2 algorithms, still believes itself to be a version-1
-implementation. The sticky part here is that, when either xntpd version
-2 or ntpd version 1 receives a packet claiming to be from a version-3
-server, it discards it without further processing. Hence there is a
-danger that in some situations synchronization with previous versions
-will fail.
-
-Xntpd is aware of this problem. In particular, when xntpd is polled
-first by a host claiming to be a previous version 1 or version 2
-implementation, xntpd claims to be a version 1 or 2 implementation,
-respectively, in packets returned to the poller. This allows xntpd to
-serve previous version clients transparently. The trouble occurs when an
-previous version is to be included in an xntpd configuration file. With
-no further indication, xntpd will send packets claiming to be version 3
-when it polls. To get around this, xntpd allows a qualifier to be added
-to configuration entries to indicate which version to use when polling.
-Hence the entry
-
-     # specify NTP version 1
-
-     peer 130.43.2.2 version 1     # apple.com (running ntpd version 1)
-     peer 130.43.2.2 version 2     # apple.com (running xntpd version 2)
-
-will cause version 1 packets to be sent to the host address 130.43.2.2.
-If you are testing xntpd against previous version servers you will need
-to be careful about this. Note that, as indicated in the RFC 1305
-specification, there is no longer support for the original NTP
-specification, popularly called NTP Version 0.
-
-There are a few other items to watch when converting an ntpd
-configuration file for use with xntpd. The first is to reconsider the
-precision entry from the configuration file, if there is one. There was
-a time when the precision claimed by a server was mostly commentary,
-with no particularly useful purpose. This is no longer the case,
-however, and so changing the precision a server claims should only be
-done with some consideration as to how this alters the performance of
-the server. The default precision claimed by xntpd will be right for
-most situations. A section later on will deal with when and how it is
-appropriate to change a server's precision without doing things you
-don't intend.
-
-Second, note that in the example configuration file above numeric
-addresses are used in the peer and server declarations. It is also
-possible to use names requiring resolution instead, but only if some
-additional configuration is done (xntpd doesn't include the resolver
-routines itself, and requires that a second program be used to do name
-resolution). If you find numeric addresses offensive, see below.
-
-Finally, "passive" and "client" entries in an ntpd configuration file
-have no useful equivalent semantics for xntpd and should be deleted.
-Xntpd won't reset the kernel variable tickadj when it starts, so you can
-remove anything dealing with this in the configuration file. The
-configuration of radio clock peers is done using different language in
-xntpd configuration files, so you will need to delete these entries from
-your ntpd configuration file and see below for the equivalent language.
-
-Traffic Monitoring
-
-Xntpd handles peers whose stratum is higher than the stratum of the
-local server and pollers using client mode by a fast path which
-minimizes the work done in responding to their polls, and normally
-retains no memory of these pollers. Sometimes, however, it is
-interesting to be able to determine who is polling the server, and how
-often, as well as who has been sending other types of queries to the
-server.
-
-To allow this, xntpd implements a traffic monitoring facility which
-records the source address and a minimal amount of other information
-from each packet which is received by the server. This can be enabled by
-adding the following line to the server's configuration file:
-
-     # enable monitoring feature
-
-     monitor yes
-
-The recorded information can be displayed using the xntpdc query
-program, described briefly below.
-
-Address-and-Mask Restrictions
-
-The address-and-mask configuration facility supported by xntpd is quite
-flexible and general, but is not an integral part of the NTP Version 3
-specification. The major drawback is that, while the internal
-implementation is very nice, the user interface sucks. For this reason
-it is probably worth doing an example here. Briefly, the facility works
-as follows. There is an internal list, each entry of which holds an
-address, a mask and a set of flags. On receipt of a packet, the source
-address of the packet is compared to each entry in the list, with a
-match being posted when the following is true:
-
-     (source_addr & mask) == (address & mask)
-
-A particular source address may match several list entries. In this case
-the entry with the most one bits in the mask is chosen. The flags
-associated with this entry are used to control the access.
-
-In the current implementation the flags always add restrictions. In
-effect, an entry with no flags set leaves matching hosts unrestricted.
-An entry can be added to the internal list using a "restrict"
-declaration. The flags associated with the entry are specified
-textually. For example, the "notrust" flag indicates that hosts matching
-this entry, while treated normally in other respects, shouldn't be
-trusted to provide synchronization even if otherwise so enabled. The
-"nomodify" flag indicates that hosts matching this entry should not be
-allowed to do run time configuration. There are many more flags, see the
-xntpd.8 man page.
-
-Now the example. Suppose you are running the server on a host whose
-address is 128.100.100.7. You would like to ensure that run time
-reconfiguration requests can only be made from the local host and that
-the server only ever synchronizes to one of a pair of off-campus servers
-or, failing that, a time source on net 128.100. The following entries in
-the configuration file would implement this policy:
-
-     # by default, don't trust and don't allow modifications
-
-     restrict default notrust nomodify
-
-     # these guys are trusted for time, but no modifications allowed
-
-     restrict 128.100.0.0 mask 255.255.0.0 nomodify
-     restrict 128.8.10.1 nomodify
-     restrict 192.35.82.50 nomodify
-
-     # the local addresses are unrestricted
-
-     restrict 128.100.100.7
-     restrict 127.0.0.1
-
-The first entry is the default entry, which all hosts match and hence
-which provides the default set of flags. The next three entries indicate
-that matching hosts will only have the nomodify flag set and hence will
-be trusted for time. If the mask isn't specified in the restrict
-keyward, it defaults to 255.255.255.255. Note that the address
-128.100.100.7 matches three entries in the table, the default entry
-(mask 0.0.0.0), the entry for net 128.100 (mask 255.255.0.0) and the
-entry for the host itself (mask 255.255.255.255). As expected, the flags
-for the host are derived from the last entry since the mask has the most
-bits set.
-
-The only other thing worth mentioning is that the restrict declarations
-apply to packets from all hosts, including those that are configured
-elsewhere in the configuration file and even including your clock
-pseudopeer(s), in any. Hence, if you specify a default set of
-restrictions which you don't wish to be applied to your configured
-peers, you must remove those restrictions for the configured peers with
-additional restrict declarations mentioning each peer separately.
-
-Authentication
-
-Xntpd supports the optional authentication procedure specified in the
-NTP Version 2 and 3 specifications. Briefly, when an association runs in
-authenticated mode, each packet transmitted has appended to it a 32-bit
-key ID and a 64-bit crypto checksum of the contents of the packet
-computed using either the Data Encryption Standard (DES) or Message
-Digest (MD5) algorithms. Note that while either of these algorithms
-provide sufficient protection from message-modification attacks,
-distribution of the former algorithm implementation is restricted to the
-U.S. and Canada, while the latter presently is free from such
-restrictions. With either algorithm the receiving peer recomputes the
-checksum and compares it with the one included in the packet. For this
-to work, the peers must share at least one encryption key and,
-furthermore, must associate the shared key with the same key ID.
-
-This facility requires some minor modifications to the basic packet
-processing procedures, as required by the specification. These
-modifications are enabled by the "authenticate" configuration
-declaration. In particular, in authenticated mode, peers which send
-unauthenticated packets, peers which send authenticated packets which
-the local server is unable to decrypt and peers which send authenticated
-packets encrypted using a key we don't trust are all marked
-untrustworthy and unsuitable for synchronization. Note that, while the
-server may know many keys (identified by many key IDs), it is possible
-to declare only a subset of these as trusted. This allows the server to
-share keys with a client which requires authenticated time and which
-trusts the server but which is not trusted by the server. Also, some
-additional configuration language is required to specify the key ID to
-be used to authenticate each configured peer association. Hence, for a
-server running in authenticated mode, the configuration file might look
-similar to the following:
-
-     # peer configuration for 128.100.100.7
-     # (expected to operate at stratum 2)
-     # fully authenticated this time
-
-     peer 128.100.49.105 key 22    # suzuki.ccie.utoronto.ca
-     peer 128.8.10.1 key 4    # umd1.umd.edu
-     peer 192.35.82.50 key 6  # lilben.tn.cornell.edu
-     authenticate yes         # enable authentication
-     keys /usr/local/bin/ntp.keys  # path for key file
-     trustedkey 1 2 14 15     # define trusted keys
-     requestkey 15            # key (7) for accessing server variables
-     controlkey 15            # key (6) for accessing server variables
-
-     #authdelay 0.000047      # authentication delay (Sun4c/50 IPX DES)
-     authdelay 0.000094       # authentication delay (Sun4c/50 IPX MD5)
-
-There are a couple of previously unmentioned things in here. The
-"authenticate yes" line enables authentication processing, while the
-"keys /usr/local/bin/ntp.keys" specifies the path to the keys file (see
-below and the xntpd.8 man page for detaiils of the file format). The
-"trustedkey" declaration identifies those keys that are known to be
-uncompromised; the remainder presumably represent the expired or
-possibly compromised keys. Both sets of keys must be declared by key
-identifier in the ntp.keys file described below. This provides a way to
-retire old keys while minimrequestkey 15izing the frequency of delicate
-key-distribution procedures. The "requestkey 15" line establishes the
-key to be used for mode-6 control messages as specified in RFC 1305 and
-used by the ntpq utility program, while the "controlkey 15" establishes
-the key to be used for mode-7 private control messages used by the
-xntpdc utility program these keys are used to prevent unauthorized
-modification of daemon variables.
-
-The "authdelay" declaration is an estimate of the amount of processing
-time taken between the freezing of a transmit timestamp and the actual
-transmission of the packet when authentication is enabled (i.e. more or
-less the time it takes for the DES or MD5 routine to encrypt a single
-block), and is used as a correction for the transmit timestamp. This can
-be computed for your CPU by the authspeed program included in the
-authstuff directory in the xntp3 distribution. The usage is illustrated
-to the following:
-
-     # for DES keys
-
-     authspeed -n 30000 auth.samplekeys
-
-     # for MD5 keys
-
-     authspeed -nd 30000 auth.samplekeys
-
-Additional utility programs included in the authstuff directory can be
-used to generate random keys, certify implementation correctness and
-display sample keys. As a general rule, keys should be chosen randomly,
-except possibly the request and control keys, which must be entered by
-the user as a password.
-
-The ntp.keys file contains the list of keys and associated key IDs the
-server knows about (for obvious reasons this file is better left
-unreadable by anyone except the server). The contents of this file might
-look like:
-
-     # ntp keys file (ntp.keys)
-
-     1    N    29233E0461ECD6AE    # des key in NTP format
-     2    M    RIrop8KPPvQvYotM    # md5 key as an ASCII random string
-     14   M    sundial             # md5 key as an ASCII string
-     15   A    sundial             # des key as an ASCII string
-
-     # the following 3 keys are identical
-
-     10   A    SeCReT
-     10   N    d3e54352e5548080
-     10   S    a7cb86a4cba80101
-
-In the keys file the first token on each line indicates the key ID, the
-second token the format of the key and the third the key itself. There
-are four key formats. An "A" indicates a DES key written as a 1-to-8
-character string in 7-bit ASCII representation, with each character
-standing for a key octet (like a Unix password). An "S" indicates a DES
-key written as a hex number in the DES standard format, with the low
-order bit (LSB) of each octet being the (odd) parity bit. An "N"
-indicates a DES key again written as a hex number, but in NTP standard
-format with the high order bit of each octet being the (odd) parity bit
-(confusing enough?). An "M" indicates an MD5 key written as a 1-to-31
-character ASCII string in the "A" format. Note that, because of the
-simple tokenizing routine, the characters ' ', '#', '\t', '\n' and '\0'
-can't be used in either a DES or MD5 ASCII key. Everything else is fair
-game, though. Key 0 (zero) is used for special purposes and should not
-appear in this file.
-
-The big trouble with the authentication facility is the keys file. It is
-a maintenance headache and a security problem. This should be fixed some
-day. Presumably, this whole bag of worms goes away if/when a generic
-security regime for the Internet is established.
-
-Query Programs
-
-Three utility query programs are included with the xntp3 distribution,
-ntpq, ntptrace and xntpdc. Ntpq is a rather handy program which sends
-queries and receives responses using NTP standard mode-6 control
-messages. Since it uses the standard control protocol specified in RFC
-1305, it may be used with NTP Version 2 and Version 3 implementations
-for both Unix and Fuzzball, but not Version 1 implementations. It is
-most useful to query remote NTP implementations to assess timekeeping
-accuracy and expose bugs in configuration or operation.
-
-Ntptrace can be used to display the current synchronization path from a
-selected host through possibly intervening servers to the primary source
-of synchronization, usually a radio clock. It works with both version 2
-and version 3 servers, but not version 1.
-
-Xnptdc is a horrid program which uses NTP private mode-7 control
-messages to query local or remote servers. The format and and contents
-of these messages are specific to xntpd. The program does allow
-inspection of a wide variety of internal counters and other state data,
-and hence does make a pretty good debugging tool, even if it is
-frustrating to use. The other thing of note about xntpdc is that it
-provides a user interface to the run time reconfiguration facility.
-
-See the respective man pages for details on the use of these programs.
-The primary reason for mentioning them here is to point out an
-inconsistancy which can be awfully annoying if it catches you, and which
-is worth keeping firmly in mind. Both xntpdc and xntpd demand that
-anything which has dimensions of time be specified in units of seconds,
-both in the configuration file and when doing run time reconfiguration.
-Both programs also print the values in seconds. Ntpq on the other hand,
-obeys the standard by printing all time values in milliseconds. This
-makes the process of looking at values with ntpq and then changing them
-in the configuration file or with xntpdc very prone to errors (by three
-orders of magnitude). I wish this problem didn't exist, but xntpd and
-its love of seconds predate the mode-6 protocol and the latter's
-(Fuzzball-inspired) millisecond orientation, making the inconsistancy
-irresolvable without considerable work.
-
-Run Time Reconfiguration
-
-Xntpd was written specifically to allow its configuration to be fully
-modifiable at run time. Indeed, the only way to configure the server is
-at run time. The configuration file is read only after the rest of the
-server has been initialized into a running, but default unconfigured,
-state. This facility was included not so much for the benefit of Unix,
-where it is handy but not strictly essential, but rather for dedicated
-platforms where the feature is more important for maintenance.
-Nevertheless, run time configuration works very nicely for Unix servers
-as well.
-
-Nearly all of the things it is possible to configure in the
-configuration file may be altered via NTP mode-7 messages using the
-xntpdc program. Mode-6 messages may also provide some limited
-configuration functionality (though the only thing you can currently do
-with mode-6 messages is set the leap-second warning bits) and the ntpq
-program provides generic support for the latter. The leap bits that can be
-set in the leap_warning variable (up to one month ahead) and in the
-leap_indication variable have a slightly different encoding than the
-usual interpretation:
-
-	Value		Action
-	 00		The daemon passes the leap bits of its 
-			synchronisation source (usual mode of operation)
-	01/10		A leap second is added/deleted
-	 11		Leap information from the sychronisation source
-			is ignored (thus LEAP_NOWARNING is passed on)
-
-Mode-6 and mode-7 messages which would modify the configuration of the
-server are required to be authenticated using standard NTP
-authentication. To enable the facilities one must, in addition to
-specifying the location of a keys file, indicate in the configuration
-file the key IDs to be used for authenticating reconfiguration commands.
-Hence the following fragment might be added to a configuration file to
-enable the mode-6 (ntpq) and mode-7 (xntpdc) facilities in the daemon:
-
-     # specify mode-6 and mode-7 trusted keys
-
-     requestkey 65535    # for mode-7 requests
-     controlkey 65534    # for mode-6 requests
-
-If the "requestkey" and/or the "controlkey" configuration declarations
-are omitted from the configuration file, the corresponding run time
-reconfiguration facility is disabled.
-
-The query programs require the user to specify a key ID and a key to use
-for authenticating requests to be sent. The key ID provided should be
-the same as the one mentioned in the configuration file, while the key
-should match that corresponding to the key ID in the keys file. As the
-query programs prompt for the key as a password, it is useful to make
-the request and control authentication keys typable (in ASCII format)
-from the keyboard.
-
-Name Resolution
-
-Xntpd includes the cability to specify host names requiring resolution
-in "peer" and "server" declarations in the configuration file. There are
-several reasons why this was not permitted in the past. Chief among
-these is the fact that name service is unreliable and the interface to
-the Unix resolver routines is synchronous. The hangups and delays
-resulting from name-resolver clanking can be unacceptable once the NTP
-server is running (and remember it is up and running before the
-configuration file is read). However, it is advantageous to resolve time
-server names, since their addresses are occasionally changed.
-
-Instead of running the resolver itself the daemon can defer this task to
-a separate program, xntpres. When the daemon comes across a "peer" or
-"server" entry with a non-numeric host address it records the relevant
-information in a temporary file and continues on. When the end of the
-configuration file has been reached and one or more entries requiring
-name resolution have been found, the server runs an instance of xntpres
-with the temporary file as an argument. The server then continues on
-normally but with the offending peers/servers omitted from its
-configuration.
-
-When xntpres successfully resolves a name from this file, it configures
-the associated entry into the server using the same mode-7 run time
-reconfiguration facility that xntpdc uses. If temporary resolver
-failures occur, xntpres will periodically retry the offending requests
-until a definite response is received. The program will continue to run
-until all entries have been resolved.
-There are several configuration requirements if xntpres is to be used.
-The path to the xntpres program must be made known to the daemon via a
-"resolver" configuration entry, and mode-7 run time reconfiguration must
-be enabled. The following fragment might be used to accomplish this:
-
-     # specify host name resolver data
-
-     resolver /local/etc/xntpres
-     keys /etc/ntp.keys
-     requestkey 65535
-
-Note that xntpres sends packets to the server with a source address of
-127.0.0.1. You should obviously avoid "restrict" modification requests
-from this address or xntpres will fail.
-
-Dealing with Frequency Tolerance Violations (Tickadj and Friends)
-
-The NTP Version 3 specification RFC 1305 calls for a maximum oscillator
-frequency tolerance of +-100 parts-per-million (ppm), which is
-representative of those components suitable for use in relatively
-inexpensive workstation platforms. For those platforms meeting this
-tolerance, NTP will automatically compensate for the frequency errors of
-the individual oscillator and no further adjustments are required,
-either to the configuration file or to various kernel variables.
-
-However, in the case of certain notorious platforms, in particular Sun
-4s, the 100-ppm tolerance is routinely violated. In such cases it may be
-necessary to adjust the values of certain kernel variables; in
-particular, "tick" and "tickadj". The variable tick is the increment in
-microseconds added to the system time on each interval-timer interrupt,
-while the variable tickadj is used by the time adjustment code as a slew
-rate. When the time is being adjusted via a call to the system routine
-adjtime(), the kernel increases or reduces tick by tickadj microseconds
-until the specified adjustment has been completed. Unfortunately, in
-most Unix implementations the tick increment must be either zero or
-plus/minus exactly tickadj microseconds, meaning that adjustments are
-truncated to be an integral multiple of tickadj (this latter behaviour
-is a misfeature, and is the only reason the xntpd code needs to concern
-itself with the internal implementation of adjtime() at all). In
-addition, the stock Unix implementation considers it an error to request
-another adjustment before a prior one has completed.
-
-Thus, to make very sure it avoids problems related to the roundoff, the
-xntpd daemon reads the values of tick and tickadj from /dev/kmem when it
-starts. It then ensures that all adjustments given to adjtime() are an
-even multiple of tickadj microseconds and computes the largest
-adjustment that can be completed in the adjustment interval (using both
-the value of tickadj and the value of tick) so it can avoid exceeding
-this limit.
-
-Unfortunately, the value of tickadj set by default is almost always too
-large for xntpd. NTP operates by continuously making small adjustments
-to the clock, usually at one-second intervals. If tickadj is set too
-large, the adjustments will disappear in the roundoff; while, if tickadj
-is too small, NTP will have difficulty if it needs to make an occasional
-large adjustment. While the daemon itself will read the kernel's values
-of tick and tickadj, it will not change the values, even if they are
-unsuitable. You must do this yourself before the daemon is started,
-either with adb or, in the running kernel only, with the tickadj program
-included in the util directory of the xntp3 distribution. Note that the
-latter program will also computes an optimal value of tickadj for NTP
-use based on the kernel's value of tick.
-
-The tickadj program can reset several other kernel variables if asked.
-It can also change the value of tick if asked, this being necessary on a
-few machines with very broken clocks, like Sun 4s. With these machines
-it should also set the value of the kernel dosynctodr variable to zero.
-This variable controls whether to synchronize the system clock to the
-time-of-day clock, something you really don't want to be happen when
-xntpd is trying to keep it under control.
-
-In order to maintain reasonable correctness bounds, as well as
-reasonably good accuracy with acceptable polling intervals, xntpd will
-complain if the frequency error is greater than 100 ppm. For machines
-with a value of tick in the 10-ms range, a change of one in the value of
-tick will change the frequency by about 100 ppm. In order to determine
-the value of tick for a particular CPU, disconnect the machine from all
-sources of time (dosynctodr = 0) and record its actual time compared to
-an outside source (eyeball-and-wristwatch will do) over a day or more.
-Multiply the time change over the day by 0.116 and add or subtract the
-result to tick, depending on whether the CPU is fast or slow. An example
-call to tickadj useful on Sun 4s is:
-
-     tickadj -t 9999 -a 5 -s
-
-which sets tick 100 ppm fast, tickadj to 5 microseconds and turns off
-the clock/calendar chip fiddle. This line can be added to the rc.local
-configuration file to automatically set the kernel variables at boot
-time.
-
-All this stuff about diddling kernel variables so the NTP daemon will
-work is really silly. If vendors would ship machines with clocks that
-kept reasonable time and would make their adjtime() system call apply
-the slew it is given exactly, independent of the value of tickadj, all
-this could go away.
-
-Tuning Your Subnet
-
-There are several parameters available for tuning the NTP subnet for
-maximum accuracy and minimum jitter. Two important parameters are the
-the "precision" and "prefer" configuration declarations. The precision
-declaration specifies the number of significant bits of the system clock
-representation relative to one second. For instance, the default value
-of -6 corresponds to 1/64 second or about 16 milliseconds.
-
-The NTP protocol makes use of the precision parameter in several places.
-It is included in packets sent to peers and is used by them to calculate
-the maximum absolute error and maximum statistical error. When faced
-with selecting one of several servers of the same stratum and about the
-same network path delay for synchronization purposes, clients will
-usually prefer to synchronize to those servers claiming the smallest
-(most negative) precision, since this maximizes the accuracy and
-minimizes the jitter apparent to application programs running on the
-client platform. Therefore, when the maximum attainable accuracy is
-required, it is important that every platform configure an accurate
-value for the precision variable. This can be done using the optional
-"precision" declaration in the configuration file:
-
-     # precision declaration
-
-     precision -18       # for microsecond clocks (Sun 4s, DEC 5000/240)
-
-When more than one eligible server exists, the NTP clock-selection and
-combining algorithms act to winnow out all except the "best" set of
-servers using several criteria based on differences between the readings
-of different servers and between successive readings of the same server.
-The result is usually a set of surviving servers that are apparently
-statistically equivalent in accuracy, jitter and stability. The
-population of survivors remaining in this set depends on the individual
-server characteristics measured during the selection process and may
-vary from time to time as the result of normal statistical variations.
-In LANs with high speed RISC-based time servers, the population can
-become somewhat unstable, with individual servers popping in and out of
-the surviving population, generally resulting in a regime called
-clockhopping.
-
-When only the smallest residual jitter can be tolerated, it may be
-convenient to elect one of the servers at each stratum level as the
-preferred one using the keyword "prefer" on the configuration
-declaration for the selected server:
-
-     # prefered server declaration
-
-     peer 128.4.1.1 prefer    # preferred server
-
-The preferred server will always be included in the surviving
-population, regardless of its characteristics and as long as it survives
-preliminary sanity checks and validation procedures.
-
-The most useful application of the prefer keyword is in high speed LANs
-equipped with precision radio clocks, such as a GPS receiver. In order
-to insure robustness, the hosts need to include outside peers as well as
-the GPS-equipped server; however, as long as that server is running, the
-synchronization preference should be that server. The keyword should
-normally be used in all cases in order to prefer an attached radio
-clock. It is probably inadvisable to use this keyword for peers outside
-the LAN, since it interferes with the carefully crafted judgement of the
-selection and combining algorithms.
-
-Provisions for Leap Seconds and Accuracy Metrics
-
-Xntpd understands leap seconds and will attempt to take appropriate
-action when one occurs. In principle, every host running xntpd will
-insert a leap second in the local timescale in precise synchronization
-with UTC. This requires that the leap-warning bits be manually activated
-some time prior to the occurance of a leap second at the primary
-(stratum 1) servers. Subsequently, these bits are propagated throughout
-the subnet depending on these servers by the NTP protocol itself and
-automatically implemented by xntpd and the time-conversion routines of
-each host. The implementation is independent of the idiosyncracies of
-the particular radio clock, which vary widely among the various devices,
-as long as the idiosyncratic behavior does not last for more than about
-20 minutes following the leap. Provisions are included to modify the
-behavior in cases where this cannot be guaranteed.
-
-While provisions for leap seconds have been carefully crafted so that
-correct timekeeping immediately before, during and after the occurance
-of a leap second is scrupulously correct, stock Unix systems are mostly
-inept in responding to the available information. This caveat goes also
-for the maximum-error and statistical-error bounds carefully calculated
-for all clients and servers, which could be very useful for application
-programs needing to calibrate the delays and offsets to achieve a near-
-simulataneous commit procedure, for example. While this information is
-maintained in the xntpd data structures, there is at present no way for
-application programs to access it. This may be a topic for further
-development.
-
-Clock Support Overview
-
-Xntpd was designed to support radio (and other external) clocks and does
-some parts of this function with utmost care. Clocks are treated by the
-protocol as ordinary NTP peers, even to the point of referring to them
-with an (invalid) IP host address. Clock addresses are of the form
-127.127.t.u, where t specifies the particular type of clock (i.e. refers
-to a particular clock driver) and u is a unit number whose
-interpretation is clock-driver dependent. This is analogous to the use
-of major and minor device numbers by Unix and permits multiple
-instantiations of clocks of the same type on the same server, should
-such magnificant redundancy be required.
-
-Because clocks look much like peers, both configuration file syntax and
-run time reconfiguration commands can be be used to control clocks in
-the same way as ordinary peers. Clocks are configured via "server"
-declarations in the configuration file, can be started and stopped using
-xntpdc and are subject to address-and-mask restrictions much like a
-normal peer, should this stretch of imagination ever be useful. As a
-concession to the need to sometimes transmit additional information to
-clock drivers, an additional configuration file is available: the
-"fudge" statement. This enables one to specify the values two time
-quantities, two integral values and two flags, the use of which is
-dependent on the particular clock driver. For example, to configure a
-PST radio clock which can be accessed through the serial device
-/dev/pst1, with propagation delays to WWV and WWVH of 7.5 and 26.5
-milliseconds, respectively, on a machine with an imprecise system clock
-and with the driver set to disbelieve the radio clock once it has gone
-30 minutes without an update, one might use the following configuration
-file entries:
-
-     # radio clock fudge fiddles
-
-     server 127.127.3.1

-Towards the Ultimate Tick
-
-This section consideres issues in providing precision time
-synchronization in NTP subnets which need the highest quality time
-available in the present technology. These issues are important in
-subnets supporting real-time services such as distributed multimedia
-conferencing and wide-are experiment control and monitoring.
-
-In the Internet of today synchronization paths often span continents and
-oceans with moderate to high variations in delay due to traffic spasms.
-NTP is specifically designed to minimize timekeeping jitter due to delay
-variations using intricately crafted filtering and selection algorithms;
-however, in cases where these variations are as much as a second or
-more, the residual jitter following these algorithms may still be
-excessive. Sometimes, as in the case of some isolated NTP subnets where
-a local source of precision time is available, such as a 1-pps signal
-produced by a calibrated cesium clock, it is possible to remove the
-jitter and retime the local clock oscillator of the NTP server. This has
-turned out to be a useful feature to improve the synchronization quality
-of time distributed in remote places where radio clocks are not
-available. In these cases special features of the xntp3 distribution are
-used together with the 1-pps signal to provide a jitter-free timing
-signal, while NTP itself is used to provide the coarse timing and
-resolve the seconds numbering.
-
-Most available radio clocks can provide time to an accuracy in the order
-of milliseconds, depending on propagation conditions, local noise levels
-and so forth. However, as a practical matter, all clocks can
-occasionally display errors significantly exceeding nominal
-specifications. Usually, the algorithms used by NTP for ordinary network
-peers, as well as radio clock "peers" will detect and discard these
-errors as discrepancies between the disciplined local clock oscillator
-and the decoded time message produced by the radio clock. Some radio
-clocks can produce a special 1-pps signal which can be interfaced to the
-server platform in a number of ways and used to substantially improve
-the (disciplined) clock oscillator jitter and wander characteristics by
-at least an order of magnitude. Using these features it is possible to
-achieve accuracies in the order of 100 microseconds with a fast RISC-
-based platform.
-
-There are three ways to implement 1-pps support, depending on the radio
-clock model, platform model and serial line interface. Each of these
-requires circuitry to convert the TTL signal produced by most clocks to
-the the EIA levels used by most serial interfaces. An example of a
-device designed to do this is presented in the gadget subdirectory
-included in the xntp3 distribtuion. Besides being useful for this
-purpose, this device includes an inexpensive modem designed for use with
-the Canadian CHU time/frequency radio station.
-
-In order to select the appropriate implementation, it is important to
-understand the underlying 1-pps mechanism used by xntpd. The 1-pps
-suport depends on a continuous source of 1-pps pulses used to calculate
-an offset within +-500 milliseconds relative to the local clock. The
-serial timecode produced by the radio or the time determined by NTP in
-absence of the radio is used to adjust the local clock within +-128
-milliseconds of the actual time. As long as the local clock is within
-this interval the 1-pps support is used to discipline the local clock
-and the timecode used only to verify that the local clock is in fact
-within the interval. Outside this interval the 1-pps support is disabled
-and the timecode used directly to control the local clock.
-
-The first method of implementation uses a dedicated serial port and
-either the bsd line discipline or System V streams module, which can be
-found in the kernel directory of the xntp3 distribution. This method can
-be used with any radio clock or in the absence of any clock. The line
-discipline and streams modules take receive timestamps in the kernel,
-specifically the interrupt routine of the serial port hardware driver.
-Using this method the port is dedicated to serve the 1-pps signal and
-cannot be used for other purposes. Instructions for implementing the
-feature, which requires rebuilding the kernel, are included in the
-modules themselves. Note that xndpd must be compiled with the -DPPSDEV
-compiler switch in this case. There is an inherent error in this method
-due to the latency of the interrupt system and remaining serial-line
-protocol modules in the order of a millisecond with Sun 4s. While the
-jitter in this latency is unavoidable, the systematic component can be
-calibrated out using a special configuration declaration:
-
-     # pps delay and baud rate
-
-     pps delay .0017 baud 19200    # pps delay (ms) and baud rate
-
-Note that the delay defaults to zero and the baud to 38400.
-
-The second method uses mechanisms embedded in the radio clock driver,
-which call the 1-pps support directly and do not require a dedicated
-serial port. Currently, only the DCF77 (German radio time service)
-driver uses this method. Instructions for implementing this are given in
-README files in the xntp3 distribution.
-
-The third method and the most accurate and intrusive of all uses the
-carrier-detect modem-control lead monitored by the serial port driver.
-This method can be used with any radio clock and 1-pps interface
-mentioned above. It requires in addition to a special streams module,
-replacement of the kernel high resolution time-of-day clock routine.
-This method is applicable only to Sun 4 platforms running SunOS 4.1.1
-and then only with either of the two onboard serial ports. It does not
-work with other platforms, operating systems or external (SBus) serial
-multiplexors.
-
-Swatting Bugs
-
-Let's say you have compiled and installed the code and put up an
-apparently relevant configuration file. In many Unix systems the xntpd
-daemon and utility programs (ntpq, ntptrace and xntpdc) are usually
-installed in the /usr/local directory along with the key file
-(ntp.keys), while the configuration file (ntp.conf) and drift file
-(ntp.drift) are installed in the /etc directory. The daemon can is
-usually started from the rc.local shell script at system boot time, but
-could be started (and stopped) at other times for debugging, etc. How do
-you verify that the daemon can form associations with remote peers and
-verify correct synchronization? For this you need the ntpq utility
-described in the ntpq.8 man page.
-
-After starting the daemon, run the ntpq program using the -n switch,
-which will avoid possible distractions due to name resolutions. Use the
-peer command to display a billboard showing the status of configured
-peers and possibly other clients poking the daemon. After operating for
-a few minutes, the display should be something like:
-

-Parting Shots
-
-There are several undocumented programs which are useful if you are
-trying to set up a clock. They can be found in the clockstuff directory
-of the xntp3 distribution. The most useful of these is the propdelay
-program, which can compute high frequency radio propagation delays
-between any two points whose latitude and longitude are known. The
-program understands something about the phenomena which allow high
-frequency radio propagation to occur, and will generally provide a
-better estimate than a calculation based on the great circle distance.
-The other two programs in the directory are clktest, which allows one to
-exercise the generic clock line discipline, and chutest, which runs the
-basic reduction algorithms used by the daemon on data received from a
-serial port.

-.Sh NAME
-.Nm ntpdate
-.Nd set the date and time via NTP
-.Sh SYNOPSIS
-.Nm
-.Op Fl bdqsv
-.Op Fl o Ar version
-.Op Fl a Ar key#
-.Op Fl e Ar authdelay
-.Op Fl k Ar keyfile
-.Op Fl p Ar samples
-.Op Fl t Ar timeout
-.Ar server ...
-.Sh DESCRIPTION
-.Nm Ntpdate
-sets the local date and time by polling the Network Time Protocol
-server(s) on the host(s) given as arguments to determine
-the correct time.  It must be run as root on the local host.  A number
-of samples are obtained from each of the servers specified and the
-standard NTP clock filter and selection algorithms are applied to select
-the best of these.  Typically,
-.Nm
-can be inserted in the
-.Pa /etc/rc.local
-startup up script to set the time of day at boot time and/or can be run
-from time\-to\-time via
-.Xr cron 8 .
-Note that
-.Nm Ns 's
-reliability and precision will improve dramatically with greater numbers
-of servers.  While a single server may be used, better performance and
-greater resistance to insanity on the part of any one server
-will be obtained by providing at least three or four servers, if not more.
-.Pp
-Time adjustments are made by
-.Nm
-in one of two ways.  If
-.Nm
-determines your clock is off by more than 0.5 seconds it will simply
-step the time by calling
-.Xr settimeofday 2 .
-If the error is less than 0.5 seconds, however, it will by default slew
-the clock's time via a call to
-.Xr adjtime 2
-with the offset.  The latter technique is less disruptive and more
-accurate when the offset is small, and works quite well when
-.Nm
-is run by
-.Xr cron 8
-every hour or two.  The adjustment made in the latter
-case is actually 50% larger than the measured offset since this will
-tend to keep a badly drifting clock more accurate (at some expense to
-stability, though this tradeoff is usually advantageous).  At boot time,
-however, it is usually better to always step the time.  This can be forced
-in all cases by specifying the
-.Fl b
-switch on the command line.  The
-.Fl s
-switch tells
-.Nm
-to log its actions via the
-.Xr syslog 3
-facility rather than to the standard output, a useful option when
-running the program from
-.Xr cron 8 .
-.Pp
-The
-.Fl d
-flag may be used to determine what
-.Nm
-will do without it actually doing it.  Information useful for general
-debugging will also be printed.  The
-.Fl q
-flag is used to perform a simple query without binding a priviledged
-UPD port.  The
-.Fl v
-enables a few diagnostic messages.  By default
-.Nm
-claims to be an NTP version 3 implementation in its outgoing packets.  As
-some older software will decline to respond to version 3 queries, the
-.Fl o Ar version
-switch can be used to force the program to poll as a version 2 or 1
-implementation instead.
-.Pp
-The number of samples
-.Nm
-acquires from each server can be set to between 1 and 8 inclusive
-using the
-.Fl p
-switch.  The default is 4.  The time it will spend waiting for a
-response can be set using the
-.Fl t
-switch, and will be rounded to a multiple of 0.2 seconds.  The default
-is 1 second, a value suitable for polling across a LAN.
-.Pp
-.Nm Ntpdate
-will authenticate its transactions if need be.  The
-.Fl a
-switch specifies that all packets should be authenticated using the
-key number indicated.  The
-.Fl k
-switch allows the name of the file from which the keys may be read
-to be modified from the default of
-.Pa /etc/ntp.keys .
-This file should be in the format described in
-.Xr xntpd 8 .
-The
-.Fl e
-option allows the specification of an authentication processing delay,
-in seconds (see
-.Xr xntpd  8
-for details).  This number is usually small enough to be negligible for
-.Nm Ns 's
-purposes, though specifying a value may improve timekeeping on very slow
-CPU's.
-.Pp
-.Nm Ntpdate
-will decline to set the date if an NTP server daemon (e.g.
-.Xr xntpd 8 )
-is running on the same host.  When running
-.Nm
-on a regular basis from
-.Xr cron 8
-as an alternative to running a daemon, doing so once every hour or two
-will result in precise enough timekeeping to avoid stepping the clock.

-.Dt NTPQ 8
-.Os
-.Sh NAME
-.Nm ntpq
-.Nd standard Network Time Protocol query program
-.Sh SYNOPSIS
-.Nm
-.Op Fl inp
-.Op Fl c Ar command
-.Op Ar host ...
-.Sh DESCRIPTION
-.Nm Ntpq
-is used to query NTP servers which implement the recommended NTP mode 6
-control message format about current state and to request changes in
-that state. The program may be run either in interactive mode or
-controlled using command line arguments. Requests to read and write
-arbitrary variables can be assembled, with raw and pretty\-printed
-output options being available.
-.Nm Ntpq
-can also obtain and print a list of peers in a common format by sending
-multiple queries to the server.
-.Pp
-If one or more request options is included on the command line when
-.Nm
-is executed, each of the requests will be sent to the NTP servers
-running on each of the hosts given as command line arguments, or on
-.Ar localhost
-by default. If no request options are given,
-.Nm
-will attempt to read commands from the standard input and execute these
-on the NTP server running on the first host given on the command line,
-again
-defaulting to
-.Ar localhost
-when no other host is specified.
-.Nm Ntpq
-will prompt for commands if the standard input is a terminal device.
-.Pp
-.Nm Ntpq
-uses NTP mode 6 packets to communicate with the NTP server, and hence
-can be used to query any compatible server on the network which permits
-it. Note that since NTP is a UDP protocol this communication will be
-somewhat unreliable, especially over large distances in terms of network
-topology.
-.Nm Ntpq
-makes one attempt to retransmit requests, and will time requests out if
-the remote host is not heard from within a suitable time out time.
-.Pp
-Command line options are described following. Specifying a command line
-option other than
-.Fl i
-or
-.Fl n
-will cause the specified query (queries) to be sent to the indicated
-host(s) immediately. Otherwise,
-.Nm
-will attempt to read interactive format commands from the standard
-input.
-The following options are available:
-.Bl -tag -width indent
-.It Fl c Ar command
-The following argument is interpreted as an interactive format
-.Ar command
-and is added to the list of commands to be executed on the specified
-host(s). Multiple
-.Fl c
-options may be given.
-.It Fl i
-Force
-.Nm
-to operate in interactive mode. Prompts will be written to the standard
-output and commands read from the standard input.
-.It Fl n
-Output all host addresses in dotted\-quad numeric format rather than
-converting to the canonical host names.
-.It Fl p
-Print a list of the peers known to the server as well as a summary of
-their state. This is equivalent to the
-.Em peers
-interactive command.
-.El
-.Sh INTERNAL COMMANDS
-.Pp
-Interactive format commands consist of a keyword followed by zero to
-four arguments. Only enough characters of the full keyword to uniquely
-identify the command need be typed. The output of a command is normally
-sent to the standard output, but optionally the output of individual
-commands may be sent to a file by appending a
-.Qq > ,
-followed by a file name, to the command line.
-.Pp
-A number of interactive format commands are executed entirely within the
-.Nm
-program itself and do not result in NTP mode 6 requests being sent to a
-server. These are described following.
-.Pp
-.Bl -tag -width indent
-.It ? Op Ar command_keyword
-A
-.Qq ?
-by itself will print a list of all the command keywords
-known to this incarnation of
-.Nm Ns .
-A
-.Qq ?
-followed by a command keyword will print function and
-usage information about the command. This command is probably a better
-source of information about
-.Nm
-than this manual page.
-.It timeout Ar milliseconds
-Specify a time out period for responses to server queries. The default
-is about 5000 milliseconds. Note that since
-.Nm
-retries each query once after a time out the total waiting time for a
-time out will be twice the time out value set.
-.It delay Ar milliseconds
-Specify a time interval to be added to timestamps included in requests
-which require authentication. This is used to enable (unreliable) server
-reconfiguration over long delay network paths or between machines whose
-clocks are unsynchronized. Actually the server does not now require time
-stamps in authenticated requests, so this command may be obsolete.
-.It host Ar hostname
-Set the host to which future queries will be sent.
-.Ar Hostname
-may be either a host name or a numeric
-address.
-.It Xo poll
-.Op Ar #
-.Op Ar verbose
-.Xc
-Poll the current server in client mode. The first argument is the number
-of times to poll (default is 1) while the second argument may be given
-to obtain a more detailed output of the results. This command is
-currently just wishful thinking.
-.It keyid Ar #
-This command allows the specification of a key number to be used to
-authenticate configuration requests. This must correspond to a key
-number the server has been configured to use for this purpose.
-.It passwd
-This command prompts you to type in a password (which will not be
-echoed) which will be used to authenticate configuration requests. The
-password must correspond to the key configured for use by the NTP server
-for this purpose if such requests are to be successful.
-.It hostnames Ar yes | Ar no
-If
-.Ar yes
-is specified, host names are printed in information
-displays. If
-.Ar no
-is given, numeric addresses are printed
-instead. The default is
-.Ar yes
-unless modified using the command line
-.Fl n
-switch.
-.It raw
-Cause all output from query commands is printed as received from the
-remote server. The only formating/intepretation done on the data is to
-transform non-ASCII data into a printable (but barely understandable)
-form.
-.It cooked
-Cause output from query commands to be
-.Qq cooked Ns .
-Variables
-which are recognized by the server will have their values reformatted
-for human consumption. Variables which
-.Nm
-thinks should have a decodeable value but didn't are marked with a
-trailing
-.Qq ? Ns .
-.It ntpversion Ar 1 | Ar 2 | Ar 3
-Set the NTP version number which
-.Nm
-claims in packets. Defaults to 3, Note that mode 6 control messages (and
-modes, for that matter) didn't exist in NTP version 1. There appear to
-be no servers left which demand version 1.
-.It authenticate Ar yes | Ar no
-Normally
-.Nm
-does not authenticate requests unless they are write requests. The
-command
-.Em authenticate yes
-causes
-.Nm
-to send authentication with all requests it makes. Authenticated
-requests causes some servers to handle requests slightly differently,
-and can occasionally melt the CPU in fuzzballs if you turn
-authentication on before doing a peer display.
-.It Xo addvars
-.Aq variable_name Ns
-.Op = Ns Aq value Ns
-.Op ,...
-.Xc
-.It Xo rmvars
-.Aq variable_name Ns
-.Op ,...
-.Xc
-.It clearvars
-The data carried by NTP mode 6 messages consists of a list of items of
-the form
-.Xo Aq variable_name Ns
-.Pf = Aq value
-.Xc
-where the
-.Qq = Ns Aq value
-is ignored, and can be omitted, in requests
-to the server to read variables.
-.Nm Ntpq
-maintains an internal list in which data to be included in control
-messages can be assembled, and sent using the
-.Em readlist
-and
-.Em writelist
-commands described below. The
-.Em addvars
-command allows variables and their optional values to be added to the
-list. If more than one variable is to be added, the list should be
-comma\-separated and not contain white space. The
-.Em rmvars
-command can be used to remove individual variables from the list, while
-the
-.Em clearlist
-command removes all variables from the list.
-.It debug Ar more | Ar less | Ar off
-Turn internal query program debugging on and off.
-.It quit
-Exit
-.Nm Ns .
-.El
-.Sh CONTROL MESSAGE COMMANDS
-Each peer known to an NTP server has a 16 bit integer
-.Em association identifier
-assigned to it. NTP control messages which carry peer variables must
-identify the peer the values correspond to by including its association
-ID. An association ID of 0 is special, and indicates the variables are
-system variables, whose names are drawn from a separate name space.
-.Pp
-Control message commands result in one or more NTP mode 6 messages being
-sent to the server, and cause the data returned to be printed in some
-format. Most commands currently implemented send a single message and
-expect a single response. The current exceptions are the
-.Em peers
-command, which will send a preprogrammed series of messages to obtain
-the data it needs, and the
-.Em mreadlist
-and
-.Em mreadvar
-commands, which will iterate over a range of associations.
-.Bl -tag -width indent
-.It associations
-Obtain and print a list of association identifiers and peer statuses
-for in\-spec peers of the server being queried. The list is printed in
-columns. The first of these is an index numbering the associations from
-1 for internal use, the second the actual association identifier
-returned by the server and the third the status word for the peer. This
-is followed by a number of columns containing data decoded from the
-status word. Note that the data returned by the \*(L"associations\*(R"
-command is cached internally in
-.Nm Ns .
-The index is then of use when dealing with stupid servers which use
-association identifiers which are hard for humans to type, in that for
-any subsequent commands which require an association identifier as an
-argument, the form
-.Em &index
-may be used as an alternative.
-.It lassocations
-Obtain and print a list of association identifiers and peer statuses
-for all associations for which the server is maintaining state. This
-command differs from the
-.Em associations
-command only for servers
-which retain state for out\-of\-spec client associations (i.e.
-fuzzballs). Such associations are normally omitted from the display when
-the
-.Em associations
-command is used, but are included in the
-output of
-.Em lassociations Ns .
-.It passociations
-Print association data concerning in\-spec peers from the internally
-cached list of associations. This command performs identically to the
-.Em associations
-except that it displays the internally stored
-data rather than making a new query.
-.It lpassociations
-Print data for all associations, including out\-of\-spec client
-associations, from the internally cached list of associations. This
-command differs from
-.Em passociations
-only when dealing with fuzzballs.
-.It pstatus Ar assocID

-.Op Ar server
-.Sh DESCRIPTION
-.Nm Ntptrace
-determines where a given Network Time Protocol (NTP) server gets
-its time from, and follows the chain of NTP servers back to their
-master time source.
-If given no arguments, it starts with
-.Dq localhost .
-.Pp
-Here is an example of the output from
-.Nm Ns :
-.Bd -literal
-% ntptrace
-localhost: stratum 4, offset 0.0019529, synch distance 0.144135
-server2.bozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
-h.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'
-.Ed
-.Pp
-On each line, the fields are (left to right): the host name, the
-host's stratum,
-the time offset between that host and the local host
-(as measured by
-.Nm Ns ;
-this is why it is not always zero for
-.Dq localhost ) ,
-the host's
-.Dq synchronization distance ,
-and (only for stratum-1 servers) the reference clock ID.  All times
-are given in seconds.  (Synchronization distance is a measure of the
-goodness of the clock's time.)
-.Sh OPTIONS
-The following options are available:
-.Bl -tag -width indent
-.It Fl d
-Turn on some debugging output.
-.It Fl n
-Turn off the printing of host names; instead, host IP addresses
-are given.  This may be necessary if a nameserver is down.
-.It Fl r Ar retries
-Set the number of retransmission attempts for each host; the default is 5.
-.It Fl t Ar timeout
-Set the retransmission timeout (in seconds); the default is 2.
-.It Fl v

-.Sh SYNOPSIS
-.Nm tickadj
-.Op Fl Adkpqs
-.Op Fl a Ar new_tickadj
-.Op Fl t Ar new_tick
-.Sh DESCRIPTION
-The
-.Nm
-program reads, and optionally modifies, several time\-keeping\-related
-variables in the running kernel, via
-.Pa /dev/kmem .
-The particular variables it is concerned with are
-.Em tick ,
-which is the number of microseconds added to the system time during a
-clock interrupt,
-.Em tickadj ,
-which sets the slew rate and resolution used by the
-.Xr adjtime 2
-system call, and
-.Em dosynctodr ,
-which indicates to the kernels on some machines whether they should internally
-adjust the system clock to keep it in line with time\-of\-day clock
-or not.
-.Pp
-By default, with no arguments,
-.Nm
-reads the variables of interest in the kernel and prints them.  At the
-same time it determines an
-.Qq optimal
-value for the value of the
-.Em tickadj
-variable if the intent is to run the
-.Xr xntpd 8
-Network Time Protocol daemon, and prints this as well.  Since the operation
-of
-.Nm
-when reading the kernel mimics the operation of similar parts of the
-.Xr xntpd 8
-program fairly closely, this is useful for doing debugging of problems
-with
-.Xr xntpd 8 Ns .
-.Pp
-Various flags may be specified to change the variables of interest in
-the running kernel:
-.Bl -tag -width indent
-.It Fl a Ar new_tickadj
-Allow one to set the variable
-.Em tickadj
-to the value specified as an argument.
-.It Fl A
-Cause
-.Em tickadj
-to be modified, but instead will set it to the internally computed
-.Qq optimal
-value.
-.It Fl d
-Add debugging information.
-.It Fl k
-Use
-.Pa /dev/kmem
-instead of
-.Pa /kernel .
-This is the default.
-.It Fl p
-Tell
-.Nm
-to set the value of the variable
-.Em noprintf
-to one.
-.It Fl q
-Tell
-.Nm
-to shut up about everything except errors. Normally
-.Nm
-is quite verbose about what it is doing.
-.It Fl s
-Tell
-.Nm
-to set the value of the variable
-.Em dosynctodr
-to zero, a prerequisite for running the
-.Xr xntpd 8
-daemon under SunOS 4.0.
-.It Fl t Ar new_tick
-May be used to reset the kernel's value of
-.Em tick ,
-a capability which is useful on machines with very broken clocks.
-.El
-.Pp
-Note that

-.Op Fl V Ar variable
-.Sh DESCRIPTION
-.Nm Xntpd
-is a daemon which sets and maintains a Unix system time\-of\-day in
-agreement with Internet standard time servers.
-.Nm Xntpd
-is a complete implementation of the Network Time Protocol (NTP) version
-3 standard, as defined by RFC 1305, but also retains compatibility with
-version 1 and 2 servers as defined by RFC 1059 and RFC 1119,
-respectively.
-.Nm Xntpd
-does all computations in fixed point arithmetic and requires no floating
-point code. The computations done in the protocol and clock adjustment
-code are carried out with high precision and with attention to the
-details which might introduce systematic bias into the computations, to
-try to maintain an accuracy suitable for synchronizing with even the
-most precise external time source.
-.Pp
-Ordinarily,
-.Nm
-reads its configuration from a configuration file at startup time. The
-default configuration file name is
-.Pa /etc/ntp.conf ,
-although this may be overridden from the command line. It is also
-possible to specify a working, although limited,
-.Nm
-configuration entirely on the command line, obviating the need for a
-configuration file. This may be particularly appropriate when
-.Nm
-is to be configured as a broadcast or multicast client, with all peers
-being determined by listening to broadcasts at run time. Various
-internal
-.Nm
-variables can be displayed and configuration options altered while the
-daemon is running through use of the
-.Xr ntpq 8
-and
-.Xr xntpdc 8
-programs.
-.Pp
-The daemon can operate in any of several modes, including symmetric
-active/passive, client/server and broadcast/multicast. A
-broadcast/multicast client can automatically discover remote servers,
-compute one-way delay correction factors and configure itself
-automatically. This makes it possible to deploy a fleet of workstations
-without specifying a configuration file or configuration details
-specific to its environment.
-.Pp

-.Nm
-(see the configuration file description for a more complete functional
-description):

-.It Fl f Ar driftfile
-Specify the location of the drift file.
-.It Fl k

-keys.
-.It Fl m

-(requires multicast kernel).
-.It Fl p
-Specify the name of the file to record the daemon's process id.
-.It Fl r
-Ordinarily, the daemon automatically compensates for the network delay

-.It Fl s
-Specify the directory to be used for creating statistics files.
-.It Fl t Ar trustedkey

-initial keyword followed by a list of arguments, some of which may be
-optional, separated by whitespace. These commands may not be continued
-over multiple lines. Arguments may be host names, host addresses written
-in numeric, dotted\-quad form, integers, floating point numbers (when

-These three commands specify various time servers to be used and/or time
-services to be provided. The
-.Em peer
-command specifies that the local server is to operate in
-.Qq symmetric active
-mode with the remote server
-.Ar host_address
-named in the command. In this mode the local server can be synchronized
-to the remote server and, in addition, the remote server can be
-synchronized by the local server. This is useful in a network of servers
-where, depending on various failure scenarios, either the local or
-remote server host may be the better source of time. The
-.Em server
-command specifies that the local server is to operate in
-.Qq client
-mode with the remote server named in the command. In
-this mode the local server can be synchronized to the remote server, but
-the remote server can never be synchronized to the local server. The
-.Em broadcast
-command specifies that the local server is to operate in
-.Qq broadcast
-mode where the local server sends periodic broadcast
-messages to a client population at the broadcast/multicast address named
-in the command. Ordinarily, this specification applies only to the local
-server operating as a transmitter; for operation as a broadcast client,
-see the
-.Em broadcastclient
-or
-.Em multicastclient
-commands elsewhere in this document. In this mode the
-.Ar host_address
-is usually the broadcast address on [one of] the local network[s] or a
-multicast address assigned to NTP. The Numbers Czar has assigned the
-address 224.0.1.1 to NTP; this is presently the only number that should
-be used. Note that the use of multicast features requires a multicast
-kernel, which is not yet ubiquitous in vendor products.
-.Pp
-The
-.Ar key
-option, when included, indicates that all packets sent to the address
-are to include authentication fields encrypted using the specified key
-number (the range of which is that of an unsigned 32 bit integer). The
-default is to not include an encryption field. The
-.Ar version
-option allows one to specify the version number to be used for outgoing
-NTP packets. Versions 1, 2, and 3 are the choices, version 3 is the
-default. The
-.Ar prefer
-option marks the host as a preferred host. All other things being equal,
-this host will be chosen for synchronization among a set of correctly
-operating hosts. The
-.Ar ttl
-option is used only with the broadcast mode. It specifies the time-to-live
-(TTL) to use on multicast packets. Selection of the proper value,
-which defaults to 127, is something of a black art and must be
-coordinated with the network admistrator(s).
-.It broadcastclient
-This directs the local server to listen for broadcast messages on the
-local network, in order to discover other servers on the same subnet.
-Upon hearing a broadcast message for the first time, the local server
-measures the nominal network delay using a brief client/server exchange
-with the remote server, then enters the
-.Qq broadcastclient
-mode,
-in which it listens for and synchronizes to succeeding broadcast
-messages. Note that, in order to avoid accidental or malicious
-disruption in this mode, both the local and remote servers must operate
-using authentication with the same trusted key and key identifier.
-.It multicastclient Op Ar IP address ...
-This command is used in the same way as the
-.Em broadcastclient
-command, but operates using IP multicasting. Support for this function
-requires a multicast kernel and the use of authentication. If one or
-more IP addresses are given, the server joins the respective multicast
-group(s). If none are given, the IP address assigned to NTP (224.0.1.1)
-is assumed.
-.It driftfile Ar filename
-This command specifies the name of the file used to record the frequency
-offset of the local clock oscillator. If the file exists, it is read at
-startup in order to set the initial frequency offset and then updated
-once per hour with the current offset computed by the daemon. If the
-file does not exist or this command is not given, the initial frequency
-offset is assumed zero. In this case, it may take some hours for the
-frequency to stabilize and the residual timing errors to subside. The
-file contains a single floating point value equal to the offset in
-parts-per-million (ppm). Note that the file is updated by first writing
-the current drift value into a temporary file and then using
-.Xr rename 2
-to replace the old version. This implies that
-.Nm
-must have write permission for the directory the drift file is located
-in, and that file system links, symbolic or otherwise, should probably
-be avoided.
-.It enable Ar auth|bclient|pll|monitor|stats Op Ar ...
-Provide a way to enable various server options. Flags not mentioned are
-unaffected. The
-.Ar auth
-flag causes the server to synchronize
-with unconfigured peers only if the peer has been correctly
-authenticated using a trusted key and key identifier. The default for
-this flag is disable (off). The
-.Ar bclient
-flag causes the server
-to listen for a message from a broadcast or multicast server, following
-which an association is automatically instantiated for that server. The
-default for this flag is disable (off). The
-.Ar pll
-flag enables
-the server to adjust its local clock, with default enable (on). If not
-set, the local clock free-runs at its intrinsic time and frequency
-offset. This flag is useful in case the local clock is controlled by
-some other device or protocol and NTP is used only to provide
-synchronization to other clients. The
-.Ar monitor
-flag enables the
-monitoring facility (see elsewhere), with default enable (on). The
-.Ar stats
-flag enables statistics facility filegen (see
-description elsewhere.), with default enable (on).
-.It disable Ar auth|bclient|pll|monitor|stats Op Ar ...
-Provide a way to disable various server options. Flags not mentioned
-are unaffected. The flags presently available are described under the
-enable command.
-.El
-.Sh "AUTHENTICATION OPTIONS"
-.Bl -tag -width indent
-.It keys Ar filename
-This command specifies the name of a file which contains the encryption
-keys and key identifiers used by
-.Nm
-when operating in authenticated mode. The format of this file is
-described later in this document.
-.It trustedkey Ar # Op Ar # ...
-This command is used to specify the encryption key identifiers which are
-trusted for the purposes of authenticating peers suitable for
-sychonization. The authentication procedures require that both the local
-and remote servers share the same key and key identifier for this
-purpose, although different keys can be used with different servers. The
-arguments are 32 bit unsigned integers. Note, however, that NTP key 0 is
-fixed and globally known. If meaningful authentication is to be
-performed the 0 key should not be trusted.
-.It requestkey Ar #
-This command specifies the key identifier to use with the
-.Xr xntpdc 8
-program, which is useful to diagnose and repair problems that affect
-.Nm
-operation. The operation of the
-.Nm xntpdc
-program are specific to this particular implementation of
-.Nm
-and can
-be expected to work only with this and previous versions of the daemon.
-Requests from a remote
-.Nm xntpdc
-program which affect the state of the
-local server must be authenticated, which requires bot the remote
-program and local server share a common key and key identifier. The
-argument to this command is a 32 bit unsigned integer. If no
-.Em controlkey
-command is included in the configuration file, or if the keys don't
-match, such requests will be ignored.
-.It controlkey Ar #
-This command specifies the key identifier to use with the
-.Xr ntpq 8
-program, which is useful to diagnose and repair problems that affect
-.Nm
-operation. The operation of the
-.Nm ntpq
-program and
-.Nm
-conform to those specified in RFC 1305. Requests from a remote
-.Nm ntpq
-program which affect the state of the local server must be
-authenticated, which requires bot the remote program and local server
-share a common key and key identifier. The argument to this command is a
-32 bit unsigned integer. If no
-.Em requestkey
-command is included in the configuration file, or if the keys don't
-match, such requests will be ignored.
-.It authdelay Ar seconds
-Indicate the amount of time it takes to encrypt an NTP authentication
-field on the local computer. This value is used to correct transmit
-timestamps when the authentication is used on outgoing packets. The
-value usually lies somewhere in the range 0.0001 seconds to 0.003
-seconds, though it is very dependent on the CPU speed of the host
-computer. The value is usually computed using the
-.Em authspeed
-program included with the distribution.
-.El
-.Sh "ACCESS CONTROL OPTIONS"
-.Bl -tag -width indent
-.It Xo restrict
-.Ar address
-.Op mask Ar numeric_mask
-.Op Ar flag
-.Op Ar ...
-.Xc
-.Nm Xntpd
-implements a general purpose address\-and\-mask based restriction list.
-The list is sorted by address and by mask, and the list is searched in
-this order for matches, with the last match found defining the
-restriction flags associated with the incoming packets. The source
-address of incoming packets is used for the match, with the 32 bit
-address being and'ed with the mask associated with the restriction entry
-and then compared with the entry's address (which has also been and'ed
-with the mask) to look for a match. The
-.Em mask
-argument defaults
-to 255.255.255.255, meaning that the
-.Em address
-is treated as the
-address of an individual host. A default entry (address 0.0.0.0, mask
-0.0.0.0) is always included and, given the sort algorithm, is always the
-first entry in the list. Note that, while
-.Em address
-is normally
-given in dotted\-quad format, the text string
-.Em default ,
-with no
-mask option, may be used to indicate the default entry.
-.Pp
-In the current implementation, flags always restrict access, i.e. an
-entry with no flags indicates that free access to the server is to be
-given. The flags are not orthogonal, in that more restrictive flags will
-often make less restrictive ones redundant. The flags can generally be
-classed into two catagories, those which restrict time service and those
-which restrict informational queries and attempts to do run time
-reconfiguration of the server. One or more of the following flags may be
-specified:
-.Bl -tag -width indent
-.It ignore
-Ignore all packets from hosts which match this entry. If this flag is
-specified neither queries nor time server polls will be responded to.
-.It noquery
-Ignore all NTP mode 6 and 7 packets (i.e. information queries and
-configuration requests) from the source. Time service is not affected.
-.It nomodify
-Ignore all NTP mode 6 and 7 packets which attempt to modify the state of
-the server (i.e. run time reconfiguration). Queries which return
-information are permitted.
-.It notrap
-Decline to provide mode 6 control message trap service to matching
-hosts. The trap service is a subsystem of the mode 6 control message
-protocol which is intended for use by remote event logging programs.
-.It lowpriotrap
-Declare traps set by matching hosts to be low priority. The number of
-traps a server can maintain is limited (the current limit is 3). Traps
-are usually assigned on a first come, first served basis, with later
-trap requestors being denied service. This flag modifies the assignment
-algorithm by allowing low priority traps to be overridden by later
-requests for normal priority traps.
-.It noserve
-Ignore NTP packets whose mode is other than 6 or 7. In effect, time
-service is denied, though queries may still be permitted.
-.It nopeer
-Provide stateless time service to polling hosts, but do not allocate
-peer memory resources to these hosts even if they otherwise might be
-considered useful as future synchronization partners.
-.It notrust
-Treat these hosts normally in other respects, but never use them as
-synchronization sources.
-.It limited
-These hosts are subject to limitation of number of clients from the same
-net. Net in this context refers to the IP notion of net (class A, class
-B, class C, etc.). Only the first
-.Qq client_limit
-hosts that have
-shown up at the server and that have been active during the last
-.Qq client_limit_period
-seconds are accepted. Requests from other
-clients from the same net are rejected. Only time request packets are
-taken into account.
-.Qq Private ,
-.Qq control ,
-and
-.Qq broadcast
-packets are not subject to client limitation and
-therefore are not contributing to client count. History of clients is
-kept using the monitoring capability of
-.Nm Ns .
-Thus, monitoring is active as long as there is a restriction entry with
-the
-.Qq limited
-flag. The default value for
-.Qq client_limit
-is 3. The default value for
-.Qq client_limit_period
-is 3600 seconds.
-.It ntpport
-This is actually a match algorithm modifier, rather than a restriction
-flag. Its presence causes the restriction entry to be matched only if
-the source port in the packet is the standard NTP UDP port (123). Both
-.Qq ntpport
-and
-.Pf non\- Qq ntpport
-may be specified. The
-.Qq ntpport
-is considered more specific and is sorted later in the
-list.
-.El
-.Pp
-Default restriction list entries, with the flags
-.Qq ignore ,
-.Qq ntpport ,
-for each of the local host's interface addresses are
-inserted into the table at startup to prevent the server from attempting
-to synchronize to its own time. A default entry is also always present,
-though if it is otherwise unconfigured no flags are associated with the
-default entry (i.e. everything besides your own NTP server is
-unrestricted).
-.Pp
-The restriction facility was added to allow the current access policies
-of the time servers running on the NSFnet backbone to be implemented
-with
-.Nm
-as well. While this facility may be otherwise useful for keeping
-unwanted or broken remote time servers from affecting your own, it
-should not be considered an alternative to the standard NTP
-authentication facility. Source address based restrictions are easily
-circumvented by a determined cracker.
-.It clientlimit Ar limit
-Set
-.Qq client_limit
-to
-.Ar limit ,
-allow configuration of
-client limitation policy. This variable defines the number of clients
-from the same network that are allowed to use the server.
-.It clientperiod Ar period
-Set
-.Qq client_limit_period ,
-allow configuration of client
-limitation policy. This variable specifies the number of seconds after
-which a client is considered inactive and thus no longer is counted for
-client limit restriction.
-.El
-.Sh "MONITORING OPTIONS"
-.Bl -tag -width indent 
-.It statsdir Ar /directory path/
-Indicate the full path of a directory where statistics files should be
-created (see below). This keyword allows the (otherwise constant)
-filegen filename prefix to be modified for file generation sets used for
-handling statistics logs (see
-.Em filegen
-statement below).
-.It statistics Ar name Ns ...
-Enable writing of statistics records. Currently, three kinds of
-statistics are supported:
-.Bl -tag -width indent
-.It loopstats
-Enable recording of loop filter statistics information. Each update of
-the local clock outputs a line of the following form to the file
-generation set named
-.Qq loopstats :
-.Dl 48773 10847.650 0.0001307 17.3478 2
-The first two fields show the date (Modified Julian Day) and time
-(seconds and fraction past UTC midnight). The next three fields show
-time offset in seconds, frequency offset in parts-per-million and time
-constant of the clock-discipline algorithm at each update of the clock.
-.It peerstats
-Enable recording of peer statistics information. This includes
-statistics records of all peers of a NTP server and of the 1-pps signal,
-where present and configured. Each valid update appends a line of the
-following form to the current element of a file generation set named
-.Qq peerstats :
-.Dl 48773 10847.650 127.127.4.1 9714 -0.001605 0.00000 0.00142
-The first two fields show the date (Modified Julian Day) and time
-(seconds and fraction past UTC midnight). The next two fields show the
-peer address in dotted-quad notation and status, respectively. The
-status field is encoded in hex in the format described in Appendix A of
-the NTP specification RFC 1305. The final three fields show the offset,
-delay and dispersion, all in seconds.
-.It clockstats
-Enable recording of clock driver statistics information. Each update
-received from a clock driver outputs a line of the following form to the
-file generation set named
-.Qq clockstats :
-.Dl 49213 525.624 127.127.4.1 93 226 00:08:29.606 D
-The first two fields show the date (Modified Julian Day) and time
-(seconds and fraction past UTC midnight). The next field shows the clock
-address in dotted-quad notation, The final field shows the last timecode
-received from the clock in decoded
-.Tn ASCII
-format, where meaningful. In
-some clock drivers a good deal of additional information can be gathered
-and displayed as well. See information specific to each clock for
-further details.
-.El
-.Pp
-Statistic files are managed using file generation sets (see
-.Em filegen
-below). The information obtained by enabling statistics recording allows
-analysis of temporal properties of a
-.Nm
-server. It is usually only useful to primary servers or maybe main
-campus servers.
-.It Xo filegen
-.Ar name
-.Op file Ar filename
-.Op type Ar typename
-.Op flag Ar flagval
-.Op link | nolink
-.Op enable | disable
-.Xc
-Configure setting of generation file set
-.Ar name .
-Generation file sets provide a means for handling files that are
-continously growing during the lifetime of a server. Server statistics
-are a typical example for such files. Generation file sets provide
-access to a set of files used to store the actual data. At any time at
-most one element of the set is being written to. The
-.Em type
-given specifies when and how data will be directed to a new element of
-the set. This way, information stored in elements of a file set that are
-currently unused are available for administrational operations without
-the risc of desturbing the operation of
-.Nm Ns .
-(Most important: they can be removed to free space for new data
-produced.) Filenames of set members are built from three elements:
-.Bl -tag -width indent
-.It prefix
-This is a constant filename path. It is not subject to modifications via
-the
-.Em filegen
-statement. It is defined by the server, usually specified as a compile
-time constant. It may, however, be configurable for individual file
-generation sets via other commands. For example, the prefix used with
-.Qq loopstats
-and
-.Qq peerstats
-filegens can be configured using the
-.Em statsdir
-statement explained above.
-.It filename
-This string is directly concatenated to the
-.Em prefix
-mentioned above (no intervening
-.Sq /
-(slash)). This can be
-modified using the
-.Ar file
-argument to the
-.Em filegen
-statement. No
-.Qq ..
-elements are allowed in this component to
-prevent filenames referring to parts outside the filesystem hierarchy
-denoted by
-.Em prefix .
-.It suffix
-This part is reflects individual elements of a file set. It is generated
-according to the
-.Em type
-of a file set as explained below.
-.El
-.Pp
-A file generation set is characterized by its type. The following types
-are supported:
-.Bl -tag -width indent
-.It none
-The file set is actually a single plain file.
-.It pid
-One element of file set is used per incarnation of a
-.Nm
-server. This type does not perform any changes to file set members
-during runtime, however it provides an easy way of seperating files
-belonging to different
-.Nm
-server incarnations. The set member filename is built by appending a dot
-.Pf ( Sq \&. Ns )
-to concatentated
-.Em prefix
-and
-.Em filename
-strings, and appending the decimal representation of the process id of
-the
-.Nm
-server process.
-.It day
-One file generation set element is created per day. The term
-.Em day
-is based on
-.Tn UTC .
-A day is defined as the period between 00:00 and 24:00
-.Tn UTC .
-The file set
-member suffix consists of a dot
-.Pf ( Qq \&. Ns )
-and a day specification in
-the form
-.Aq YYYYMMDD .
-.Em YYYY
-is a 4 digit year number (e.g. 1992).
-.Em MM
-is a two digit month number.
-.Em DD
-is a two digit day number. Thus, all information written at December
-10th, 1992 would end up in a file named
-.Qq <prefix><filename>.19921210 .
-.It week
-Any file set member contains data related to a certain week of a year.
-The term
-.Em week
-is definied by computing
-.Qq day of year
-modulo 7. Elements of
-such a file generation set are distinguished by appending the following
-suffix to the file set filename base: a dot, a four digit year number,
-the letter
-.Qq W ,
-and a two digit week number. For example,
-information from Jamuary, 10th 1992 would end up in a file with suffix
-.Qq .1992W1 .
-.It month
-One generation file set element is generated per month. The file name
-suffix consists of a dot, a four digit year number, and a two digit
-month.
-.It year
-One generation file element is generated per year. The filename suffix
-consists of a dot and a 4 digit year number.
-.It age
-This type of file generation sets changes to a new element of the file
-set every 24 hours of server operation. The filename suffix consists of
-a dot, the letter
-.Qq a ,
-and an eight digit number. This number is
-taken to be the number of seconds the server is running at the start of
-the corresponding 24 hour period.
-.El
-.Pp
-Information is only written to a file generation set when this set is
-.Qq enabled .
-Output is prevented by specifying
-.Qq disabled .
-.Pp
-It is convenient to be able to access the
-.Em current
-element of a file generation set by a fixed name. This feature is
-enabled by specifying
-.Qq link
-and disabled using
-.Qq nolink .
-If
-.Qq link
-is specified, a hard link from the
-current file set element to a file without suffix is created. When there
-is already a file with this name and the number of links of this file is
-one, it is renamed appending a dot, the letter
-.Qq C ,
-and the pid
-of the
-.Nm
-server process. When the number of links is greater than one, the file
-is unlinked. This allows the current file to be accessed by a constant
-name.
-.El
-.Sh "MISCELLANEOUS OPTIONS"
-.Bl -tag -width indent
-.It precision Ar #
-This command specifies the nominal precision of the local clock. The
-value is an integer approximately equal to the base 2 logarithm of the
-local timekeeping precision in seconds. Normally, the daemon determines
-the precision automatically at startup, so this command is necessary
-only in special cases when the precision cannot be determined
-automatically.
-.It broadcastdelay Ar seconds
-The broadcast and multicast modes require a special calibration to
-determine the network delay between the local and remote servers.
-Ordinarily, this is done automatically by the initial protocol exchanges
-between the local and remote servers. In some cases, the calibration
-procedure may fail due to network or server access controls, for
-example. This command specifies the default delay to be used under these
-circumstances. Typically (for Ethernet), a number between 0.003 and
-0.007 seconds is appropriate. The default when this command is not used
-is 0.004 seconds.
-.It Xo trap
-.Ar host_address
-.Op port Ar port_number
-.Op interface Ar interface_addess
-.Xc
-This command configures a trap receiver at the given host address and
-port number for sending messages with the specified local interface
-address. If the port number is unspecified a value of 18447 is used. If
-the interface address is not specified the message is sent with a source
-address which is that of the local interface the message is sent
-through. Note that on a multihomed host the interface used may vary from
-time to time with routing changes.
-.Pp
-The trap receiver will generally log event messages and other
-information from the server in a log file. While such monitor programs
-may also request their own trap dynamically, configuring a trap receiver
-will ensure that no messages are lost when the server is started.
-.It Xo setvar
-.Ar variable
-.Op Ar default
-.Xc
-This command adds an additional system variable. These variables can be
-used to distribute additional information such as the access policy. If
-the variable of the form <name>=<value> is followed by the
-.Em default
-keyword the variable will be listed as part of the default system
-variables
-.Pf ( Nm ntpq
-rv command). These additional variables serve informational purposes only.
-They are not related to the protocol other that they can be listed. The
-known protocol variables will always overide any variables defined via
-the
-.Em setvar
-mechanism.
-.Pp
-There are three special variables that contain the names of all variable
-of the same group. The
-.Em sys_var_list
-holds the names of all system variables. The
-.Em peer_var_list
-holds the names of all peer variables and the
-.Em clock_var_list
-hold the names of the reference clock variables.
-.It monitor Ar yes|no
-.It authenticate Ar yes|no
-These commands have been superseded by the
-.Em enable
-and
-.Em disable
-commands. They are listed here for historical purposes.
-.El
-.Sh "AUTHENTICATION KEY FILE FORMAT"
-The
-.Tn NTP
-standard specifies an extension allowing verification of the
-authenticity of received NTP packets, and to provide an indication of
-authenticity in outgoing packets. This is implemented in
-.Nm
-using the DES or MD5 algorithms to compute a digital signature, or
-message-digest. The specification allows any one of possibly 4 billion
-keys, numbered with 32 bit key identifiers, to be used to authenticate
-an association. The servers involved in an association must agree on the
-key and key identifier used to authenticate their data, though they must
-each learn the key and key identifer independently. In the case of DES,
-the keys are 56 bits long with, depending on type, a parity check on
-each byte. In the case of MD5, the keys are 64 bits (8 bytes).
-.Nm Xntpd
-reads its keys from a file specified using the
-.Fl k
-command line option or the
-.Em keys
-statement in the configuration file. While key number 0 is fixed by the
-.Tn NTP
-standard (as 56 zero bits) and may not be changed, one or more of
-the keys numbered 1 through 15 may be arbitrarily set in the keys file.
-.Pp
-The key file uses the same comment conventions as the configuration
-file. Key entries use a fixed format of the form:
-.Pp
-.Dl keyno type key
-.Pp
-where
-.Em keyno
-is a positive integer,
-.Em type
-is a single
-character which defines the format the key is given in, and
-.Em key
-is the key itself.
-.Pp
-The key may be given in one of three different formats, controlled by
-the
-.Em type
-character. The three key types, and corresponding
-formats, are listed following:
-.Bl -tag -width indent
-.It S
-The
-.Em key
-is a 64 bit hexadecimal number in the format specified
-in the DES document, that is the high order 7 bits of each octet are
-used to form the 56 bit key while the low order bit of each octet is
-given a value such that odd parity is maintained for the octet. Leading
-zeroes must be specified (i.e. the key must be exactly 16 hex digits
-long) and odd parity must be maintained. Hence a zero key, in standard
-format, would be given as
-.Em 0101010101010101 .
-.It N
-The
-.Em key
-is a 64 bit hexadecimal number in the format specified
-in the
-.Tn NTP
-standard. This is the same as the DES format except the bits
-in each octet have been rotated one bit right so that the parity bit is
-now the high order bit of the octet. Leading zeroes must be specified
-and odd parity must be maintained. A zero key in NTP format would be
-specified as
-.Em 8080808080808080 .
-.It A
-The
-.Em key
-is a 1\-to\-8 character
-.Tn ASCII
-string. A key is formed from this by using the lower order 7 bits of the
-.Tn ASCII
-representation of
-each character in the string, with zeroes being added on the right when
-necessary to form a full width 56 bit key, in the same way that
-encryption keys are formed from Unix passwords.
-.It M
-The
-.Em key
-is a 1\-to\-8 character
-.Tn ASCII
-string, using the MD5
-authentication scheme. Note that both the keys and the authentication
-schemes (DES or MD5) must be identical between a set of peers sharing
-the same key number.
-.El
-.Pp
-One of the keys may be chosen,
-by way of the configuration file
-.Em requestkey
-statement, to authenticate run time configuration requests made using
-the
-.Xr xntpdc 8
-program. The latter program obtains the key from the terminal as a
-password, so it is generally appropriate to specify the key chosen to be
-used for this purpose in
-.Tn ASCII
-format.
-.Sh PRIMARY CLOCK SUPPORT
-.Nm Xntpd
-can be optionally compiled to include support for a number of types of
-reference clocks. A reference clock will generally (though not always)
-be a radio timecode receiver which is synchronized to a source of
-standard time such as the services offered by the NRC in Canada and NIST
-in the U.S. The interface between the computer and the timecode receiver
-is device dependent and will vary, but is often a serial port.
-.Pp
-Support for the various reference clock drivers is conditionally
-compiled using the compiler define codes described elsewhere. An attempt
-to configure a reference clock when specific support is not available or
-the hardware port has not been appropriately configured results in a
-scolding remark to the system log file, but is otherwise non hazardous.
-.Pp
-For the purposes of configuration,
-.Nm
-treats reference clocks in a manner analogous to normal
-.Tn NTP
-peers as
-much as possible. Reference clocks are referred to by address, much as a
-normal peer is, though an invalid IP address is used to distinguish them
-from normal peers. Reference clock addresses are of the form
-.Em 127.127.t.u
-where
-.Em t
-is an integer denoting the clock type and
-.Em u
-indicates the type\-specific unit number. Reference clocks are
-configured using a
-.Em server
-statement in the configuration file where the
-.Em host_address
-is the clock address. The
-.Em key,
-.Em version
-and
-.Em ttl
-options are not used for reference clock support; however, the
-.Em prefer
-option can be useful to persuade the server to cherish a reference clock
-with somewhat more enthusiasm than other reference clocks or peers, if
-this is advisable. Clock addresses may generally be used anywhere in the
-configuration file a normal IP address can be used, for example, in
-.Em restrict
-statements, although such use would normally be considered strange.
-.Pp
-Reference clock support provides the
-.Em fudge
-command, which can be used to configure reference clocks in special
-ways. Following is the generic format that applies to this command:
-.Pp
-fudge
-.Ar 127.127.t.u
-.Op time1 Ar secs
-.Op time2 Ar secs
-.Op stratum Ar int
-.Op refid Ar int
-.Op flag1 Ar 0|1
-.Op flag2 Ar 0|1
-.Op flag3 Ar 0|1
-.Op flag4 Ar 0|1
-.Pp
-The
-.Em time1
-and
-.Em time2
-options are specified in fixed point seconds and used in some clock
-drivers as calibration constants. By convention, and unless indicated
-otherwise,
-.Em time1
-is used as a calibration constant to adjust the nominal time offset of a
-particular clock to agree with an external standard, such as a precision
-PPS signal. The specified offset is in addition to the propagation delay
-provided by other means, such as internal DIPswitches. The
-.Em stratum
-option is a number in the range zero to 15 and is used to assign a
-nonstandard operating stratum to the clock. The
-.Em refid
-option is an
-.Tn ASCII
-string in the range one to four characters and is
-used to assign a nonstandard reference identifier to the clock. Finally,
-the four binary flags
-.Em flag1,
-.Em flag2,
-.Em flag3
-and
-.Em flag4
-are used for customizing the clock driver. The interpretation of these
-values, and whether they are used at all, is a function of the needs of
-the particular clock driver. However, by convention, and unless
-indicated otherwise,
-.Em flag3
-is used to attach the ppsclock streams module to the configured driver,
-while
-.Em flag4
-is used to enable recording verbose monitoring data to the clockstats
-file configured with the
-.Em filegen
-command. Further information on the ppsclock streams module is in the
-.Pa README
-file in the
-.Pa ./kernel
-directory in the current xntp3 program
-distribution. Further information on this feature is available in the
-.Pa ./scripts/stats
-directory in the same distribution.
-.Pp
-Ordinarily, the stratum of a reference clock is by default zero. Since
-the
-.Nm
-daemon adds one to the stratum of each peer, a primary server ordinarily
-displays stratum one. In order to provide engineered backups, it is
-often useful to specify the reference clock stratum as greater than
-zero. The
-.Em stratum
-option is used for this purpose. Also, in cases involving both a
-reference clock and a 1-pps discipline signal, it is useful to specify
-the reference clock identifier as other than the default, depending on
-the driver. The
-.Em refid
-option is used for this purpose. Except where noted, these options apply
-to all clock drivers.
-.Pp
-.Nm Xntpd
-on Unix machines currently supports several different types of clock
-hardware plus a special pseudo\-clock used for backup or when no other
-clock source is available. In the case of most of the clock drivers,
-support for a 1-pps precision timing signal is available as described in
-the
-.Pa README
-file in the
-.Pa ./doc
-directory of the xntp3 progam distribution.
-The clock drivers, and the addresses used to configure them, are
-described in the
-.Pa README.refclocks
-in the
-.Pa doc
-directory of the current
-program distribution.
-.Sh VARIABLES
-Most variables used by the
-.Tn NTP
-protocol can be examined with the
-.Nm xntpdc
-(mode 7 messages) and the
-.Nm ntpq
-(mode 6 messages). Currently very few variables can be modified via mode
-6 messages. These variables are either created with the
-.Em setvar
-directive or the leap warning variables. The leap warning bits that can
-be set in the
-.Em leapwarning
-variable (up to one month ahead). Both, the
-.Em leapwarning
-and the
-.Em leapindication
-variable, have a slightly different encoding than the usual
-.Em leap
-bits interpretation:
-.Bl -tag -width indent
-.It 00
-The daemon passes the leap bits of its synchronisation source (usual
-mode of operation).
-.It 01/10
-A leap second is added/deleted (operator forced leap second).

-Leap information from the sychronisation source is ignored (thus
-LEAP_NOWARNING is passed on).

-.Sh NAME
-.Nm xntpdc
-.Nd query/control program for the Network Time Protocol daemon
-.Sh SYNOPSIS
-.Nm xntpdc
-.Op Fl ilnps
-.Op Fl c Ar command
-.Op Ar host ...
-.Sh DESCRIPTION
-.Nm Xntpdc
-is used to query the
-.Xr xntpd 8
-daemon about its current state and to request changes in that state. The
-program may be run either in interactive mode or controlled using
-command line arguments. Extensive state and statistics information is
-available through the
-.Nm
-interface. In addition, nearly all the configuration options which can
-be specified at start up using
-.Nm xntpd Ns 's
-configuration file may also be specified at run time using
-.Nm Ns .
-.Pp
-If one or more request options is included on the command line when
-.Nm
-is executed, each of the requests will be sent to the
-.Tn NTP
-servers
-running on each of the hosts given as command line arguments, or on
-.Ar localhost
-by default. If no request options are given,
-.Nm
-will attempt to read commands from the standard input and execute these
-on the
-.Tn NTP
-server running on the first host given on the command line,
-again defaulting to
-.Ar localhost
-when no other host is specified.
-.Nm Xntpdc
-will prompt for commands if the standard input is a terminal device.
-.Pp
-.Nm Xntpdc
-uses
-.Tn NTP
-mode 7 packets to communicate with the
-.Tn NTP
-server, and hence
-can be used to query any compatible server on the network which permits
-it. Note that since
-.Tn NTP
-is a UDP protocol this communication will be
-somewhat unreliable, especially over large distances in terms of network
-topology.
-.Nm Xntpdc
-makes no attempt to retransmit requests, and will time requests out if
-the remote host is not heard from within a suitable time out time.
-.Pp
-Command line options are described following. Specifying a command line
-option other than
-.Fl i
-or
-.Fl n
-will cause the specified query (queries) to be sent to the indicated
-host(s) immediately. Otherwise,
-.Nm
-will attempt to read interactive format commands from the standard
-input.
-.Bl -tag -width indent
-.It Fl c
-The following argument is interpreted as an interactive format command
-and is added to the list of commands to be executed on the specified
-host(s). Multiple
-.Fl c
-options may be given.
-.It Fl i
-Force
-.Nm
-to operate in interactive mode. Prompts will be written to the standard
-output and commands read from the standard input.
-.It Fl l
-Obtain a list of peers which are known to the server(s). This switch is
-equivalent to
-.Qq -c listpeers .
-.It Fl n
-Output all host addresses in dotted\-quad numeric format rather than
-converting to the canonical host names.
-.It Fl p
-Print a list of the peers known to the server as well as a summary of
-their state. This is equivalent to
-.Qq -c peers .
-.It Fl s
-Print a list of the peers known to the server as well as a summary of
-their state, but in a slightly different format than the
-.Fl p
-switch. This is equivalent to
-.Qq -c dmpeers .
-.El
-.Sh INTERNAL COMMANDS
-Interactive format commands consist of a keyword followed by zero to
-four arguments. Only enough characters of the full keyword to uniquely
-identify the command need be typed. The output of a command is normally
-sent to the standard output, but optionally the output of individual
-commands may be sent to a file by appending a
-.Qq > ,
-followed by a
-file name, to the command line.
-.Pp
-A number of interactive format commands are executed entirely within the
-.Nm
-program itself and do not result in
-.Tn NTP
-mode 7 requests being sent to a
-server. These are described following:
-.Pp
-.Bl -tag -width indent
-.It Xo ?
-.Op Ar command_keyword
-.Xc
-A
-.Em ?
-by itself will print a list of all the command keywords
-known to this incarnation of
-.Nm Ns .
-A
-.Em ?
-followed by a command keyword will print function and
-usage information about the command. This command is probably a better
-source of information about
-.Nm
-than this manual page.
-.It help Ar command_keyword
-A synonym for the
-.Em ?
-command.
-.It timeout Ar millseconds
-Specify a time out period for responses to server queries. The default
-is about 8000 milliseconds.
-.It delay Ar milliseconds
-Specify a time interval to be added to timestamps included in requests
-which require authentication. This is used to enable (unreliable) server
-reconfiguration over long delay network paths or between machines whose
-clocks are unsynchronized.
-.It host Ar hostname
-Set the host to which future queries will be sent.
-.Ar Hostname
-may be either a host name or a numeric (dotted quad) dmaddress.
-.It keyid Ar #
-This command allows the specification of a key number to be used to
-authenticate configuration requests. This must correspond to the key
-number the server has been configured to use for this purpose.
-.It passwd
-This command prompts you to type in a password (which will not be
-echoed) which will be used to authenticate configuration requests. The
-password must correspond to the key configured for use by the
-.Tn NTP
-server for this purpose if such requests are to be successful.
-.It hostnames Ar yes|no
-If
-.Ar yes
-is specified, host names are printed in information
-displays. If
-.Ar no
-is given, numeric addresses are printed
-instead. The default is
-.Ar yes
-unless modified using the command line
-.Fl n
-switch.
-.It quit
-Exit
-.Nm Ns .
-.El
-.Sh QUERY COMMANDS
-Query commands result in
-.Tn NTP
-mode 7 packets containing requests for
-information being sent to the server. These are
-.Qq read\-only
-commands in that they make no modification of the server configuration
-state.
-.Bl -tag -width indent
-.It listpeers
-Obtain and print a brief list of the peers for which the server is
-maintaining state. These should include all configured peer associations
-as well as those peers whose stratum is such that they are considered by
-the server to be possible future synchronization candidates.
-.It peers
-Obtain a list of peers for which the server is maintaining state, along
-with a summary of that state. Summary information includes the address
-of the remote peer, the local interface address (0.0.0.0 if a local
-address has yet to be determined), the stratum of the remote peer (a
-stratum of 16 indicates the remote peer is unsynchronized), the polling
-interval, in seconds, the reachability register, in octal, and the
-current estimated delay, offset and dispersion of the peer, all in
-seconds. In addition, the character in the left margin indicates the
-mode this peer entry is operating in. A
-.Qq +
-denotes symmetric
-active, a
-.Qq -
-indicates symmetric passive, a
-.Qq =
-means
-the remote server is being polled in client mode, a
-.Qq ^
-indicates that the server is broadcasting to this address, a
-.Qq ~
-denotes that the remote peer is sending broadcasts and a
-.Qq *
-marks the peer the server is currently synchronizing to.
-.Pp
-The contents of the host field may be one of four forms. It may be a
-host name, an IP address, a reference clock implementation name with its
-parameter or
-.Qq REFCLK(<implementation number>, <parameter>) .
-On
-.Qq hostnames no
-only IP\-addresses will be displayed.
-.It dmpeers
-A slightly different peer summary list. Identical to the output of the
-.Em peers
-command except for the character in the leftmost column. Characters only
-appear beside peers which were included in the final stage of the clock
-selection algorithm. A
-.Qq \&.
-indicates that this peer was cast off
-in the falseticker detection, while a
-.Qq +
-indicates that the
-peer made it through. A
-.Qq *
-denotes the peer the server is
-currently synchronizing with.
-.It Xo showpeer
-.Ar peer_address
-.Op Ar addr2
-.Op Ar addr3
-.Op Ar addr4
-.Xc
-Show a detailed display of the current peer variables for one or more
-peers. Most of these values are described in the
-.Tn NTP
-Version 2 specification.
-.It Xo pstats
-.Ar peer_address
-.Op Ar addr2
-.Op Ar addr3
-.Op Ar addr4
-.Xc
-Show per\-peer statistic counters associated with the specified peer(s).
-.It Xo clockinfo
-.Ar clock_peer_address
-.Op Ar addr2
-.Op Ar addr3
-.Op Ar addr4
-.Xc
-Obtain and print information concerning a peer clock. The values
-obtained provide information on the setting of fudge factors and other
-clock performance information.
-.It kerninfo
-Obtain and print kernel phase-lock loop operating parameters. This
-information is available only if the kernel has been specially modified
-for a precision timekeeping function.
-.It loopinfo Op Ar oneline|multiline
-Print the values of selected loop filter variables. The loop filter is
-the part of
-.Tn NTP
-which deals with adjusting the local system clock. The
-.Qq offset
-is the last offset given to the loop filter by the
-packet processing code. The
-.Qq frequency
-is the frequency error
-of the local clock in parts-per-million (ppm). The
-.Qq time_const
-controls the
-.Qq stiffness
-of the phase-lock loop and thus the speed at
-which it can adapt to oscillator drift. The
-.Qq watchdog timer
-value is the number of seconds which have elapsed since the last sample
-offset was given to the loop filter. The
-.Ar oneline
-and
-.Ar multiline
-options specify the format in which this information
-is to be printed, with
-.Ar multiline
-as the default.
-.It sysinfo
-Print a variety of system state variables, i.e. state related to the
-local server. All except the last four lines are described in the
-.Tn NTP
-Version 3 specification, RFC 1305. The
-.Qq system flags
-show various system flags, some of which can be set and cleared by the
-.Qq enable
-and
-.Qq disable
-configuration commands,
-respectively. The
-.Qq stability
-is the residual frequency error
-remaining after the system frequency correction is applied and is
-intended for maintenance and debugging. In most architectures, this
-value will initially decrease from as high as 500 ppm to a nominal value
-in the range .01 to 0.1 ppm. If it remains high for some time after
-starting the daemon, something may be wrong with the local clock, or the
-value of the kernel variable
-.Qq tick
-may be incorrect. The
-.Qq broadcastdelay
-shows the default broadcast delay, as set by
-the
-.Qq broadcastdelay
-configuration command, while the
-.Qq authdelay
-shows the default authentication delay, as set by
-the
-.Qq authdelay
-configuration command.
-.It sysstats
-Print statistics counters maintained in the protocol module.
-.It memstats
-Print statistics counters related to memory allocation
-code.
-.It iostats
-Print statistics counters maintained in the input\-output module.
-.It timerstats
-Print statistics counters maintained in the timer/event queue support
-code.
-.It reslist
-Obtain and print the server's restriction list. This list is (usually)
-printed in sorted order and may help to understand how the restrictions
-are applied.
-.It monlist Op Ar version
-Obtain and print traffic counts collected and maintained by the monitor
-facility. The version number should not normally need to be specified.
-.It Xo clkbug
-.Ar clock_peer_address
-.Op Ar addr2
-.Op Ar addr3
-.Op Ar addr4
-.Xc
-Obtain debugging information for a reference clock driver. This
-information is provided only by some clock drivers and is mostly
-undecodable without a copy of the driver source in hand.
-.El
-.Sh RUNTIME CONFIGURATION REQUESTS
-All requests which cause state changes in the server are authenticated
-by the server using a configured
-.Tn NTP
-key (the facility can also be
-disabled by the server by not configuring a key). The key number and the
-corresponding key must also be made known to
-.Nm Ns .
-This can be done using the
-.Em keyid
-and
-.Em passwd
-commands, the latter of which will prompt at the terminal for a password
-to use as the encryption key. You will also be prompted automatically
-for both the key number and password the first time a command which
-would result in an authenticated request to the server is given.
-Authentication not only provides verification that the requester has
-permission to make such changes, but also gives an extra degree of
-protection again transmission errors.
-.Pp
-Authenticated requests always include a timestamp in the packet data,
-which is included in the computation of the authentication code. This
-timestamp is compared by the server to its receive time stamp. If they
-differ by more than a small amount the request is rejected. This is done
-for two reasons. First, it makes simple replay attacks on the server, by
-someone who might be able to overhear traffic on your LAN, much more
-difficult. Second, it makes it more difficult to request configuration
-changes to your server from topologically remote hosts. While the
-reconfiguration facility will work well with a server on the local host,
-and may work adequately between time\-synchronized hosts on the same
-LAN, it will work very poorly for more distant hosts. As such, if
-reasonable passwords are chosen, care is taken in the distribution and
-protection of keys and appropriate source address restrictions are
-applied, the run time reconfiguration facility should provide an
-adequate level of security.
-.Pp
-The following commands all make authenticated requests:
-.Bl -tag -width indent
-.It Xo addpeer
-.Ar peer_address
-.Op Ar keyid
-.Op Ar version#
-.Op Ar prefer
-.Xc
-Add a configured peer association at the given address and operating in
-symmetric active mode. Note that an existing association with the same
-peer may be deleted when this command is executed, or may simply be
-converted to conform to the new configuration, as appropriate. If the
-optional
-.Ar keyid
-is a nonzero integer, all outgoing packets to
-the remote server will have an authentication field attached encrypted
-with this key. If the value is 0 (or not given) no authentication will
-be done. The
-.Ar version#
-can be 1, 2 or 3 and defaults to 3. The
-.Ar prefer
-keyword indicates a preferred peer (and thus will be
-used primarily for clock synchronisation if possible). The preferred
-peer also determines the validity of the PPS signal - if the preferred
-peer is suitable for synchronisation so is the PPS signal.
-.It Xo addserver
-.Ar peer_address
-.Op Ar keyid
-.Op Ar version#
-.Op Ar prefer
-.Xc
-Identical to the
-.Em addpeer
-command, except that the operating mode is client.
-.It Xo broadcast
-.Ar peer_address
-.Op Ar keyid
-.Op Ar version#
-.Xc
-Identical to the
-.Em addpeer
-command, except that the operating mode is broadcast. In this case a
-valid key identifier and key are required. The
-.Ar peer_address
-parameter can be the broadcast address of the local network or a
-multicast group address assigned to
-.Tn NTP .
-If a multicast address, a
-multicast-capable kernel is required.
-.It Xo unconfig
-.Ar peer_address
-.Op Ar addr2
-.Op Ar addr3
-.Op Ar addr4
-.Xc
-This command causes the configured bit to be removed from the specified
-peer(s). In many cases this will cause the peer association to be
-deleted. When appropriate, however, the association may persist in an
-unconfigured mode if the remote peer is willing to continue on in this
-fashion.
-.It Xo fudge
-.Ar peer_address
-.Op Ar time1
-.Op Ar time2
-.Op Ar stratum
-.Op Ar refid
-.Xc
-This command provides a way to set certain data for a reference clock.
-See the source listing for further information.
-.It Xo enable
-.Ar auth|bclient|pll|monitor|stats
-.Op Ar ...
-.Xc
-Provide a way to enable various server options. Flags not mentioned are
-unaffected. The
-.Ar auth
-flag causes the server to synchronize
-with unconfigured peers only if the peer has been correctly
-authenticated using a trusted key and key identifier. The default for
-this flag is disable (off). The
-.Ar bclient
-flag causes the server
-to listen for a message from a broadcast or multicast server, following
-which an association is automatically instantiated for that server. The
-default for this flag is disable (off). The
-.Ar pll
-flag enables
-the server to adjust its local clock, with default enable (on). If not
-set, the local clock free-runs at its intrinsic time and frequency
-offset. This flag is useful in case the local clock is controlled by
-some other device or protocol and
-.Tn NTP
-is used only to provide
-synchronization to other clients. The
-.Ar monitor
-flag enables the
-monitoring facility (see elsewhere), with default disable (off). The
-.Ar stats
-flag enables statistics facility filegen (see
-description elsewhere.), with default enable (on).
-.It Xo disable
-.Ar auth|bclient|pll|monitor|stats
-.Op Ar ...
-.Xc
-Provide a way to disable various server options. Flags not mentioned
-are unaffected. The flags presently available are described under the
-enable command.
-.It Xo restrict
-.Ar address
-.Ar mask
-.Ar flag
-.Op Ar flag
-.Xc
-Cause flag(s) to be added to an existing restrict list entry, or adds a
-new entry to the list with the specified flag(s). The possible choices
-for the flags arguments are given in the following list:
-.Bl -tag -width indent
-.It ignore
-Ignore all packets from hosts which match this entry. If this flag is
-specified neither queries nor time server polls will be responded to.
-.It noquery
-Ignore all
-.Tn NTP
-mode 7 packets (i.e. information queries and
-configuration requests) from the source. Time service is not affected.
-.It nomodify
-Ignore all
-.Tn NTP
-mode 7 packets which attempt to modify the state of the
-server (i.e. run time reconfiguration). Queries which return information
-are permitted.
-.It notrap
-Decline to provide mode 6 control message trap service to matching
-hosts. The trap service is a subsystem of the mode 6 control message
-protocol which is intended for use by remote event logging programs.
-.It lowpriotrap
-Declare traps set by matching hosts to be low priority. The number of
-traps a server can maintain is limited (the current limit is 3). Traps
-are usually assigned on a first come, first served basis, with later
-trap requestors being denied service. This flag modifies the assignment
-algorithm by allowing low priority traps to be overridden by later
-requests for normal priority traps.
-.It noserve
-Ignore
-.Tn NTP
-packets whose mode is other than 7. In effect, time service
-is denied, though queries may still be permitted.
-.It nopeer
-Provide stateless time service to polling hosts, but do not allocate
-peer memory resources to these hosts even if they otherwise might be
-considered useful as future synchronization partners.
-.It notrust
-Treat these hosts normally in other respects, but never use them as
-synchronization sources.
-.It limited
-These hosts are subject to limitation of number of clients from the same
-net. Net in this context refers to the IP notion of net (class A, class
-B, class C, etc.). Only the first
-.Qq client_limit
-hosts that have
-shown up at the server and that have been active during the last
-.Qq client_limit_period
-seconds are accepted. Requests from other
-clients from the same net are rejected. Only time request packets are
-taken into account.
-.Qq Private ,
-.Qq control ,
-and
-.Qq broadcast
-packets are not subject to client limitation and
-therefore are not contributing to client count. History of clients is
-kept using the monitoring capability of
-.Xr xntpd 8 .
-Thus, monitoring is active as long as there is a restriction entry with
-the
-.Ar limited
-flag. The default value for
-.Qq client_limit
-is 3. The default value for
-.Qq client_limit_period
-is 3600
-seconds. Currently both variables are not runtime configurable.
-.It ntpport
-This is actually a match algorithm modifier, rather than a restriction
-flag. Its presence causes the restriction entry to be matched only if
-the source port in the packet is the standard
-.Tn NTP
-UDP port (123). Both
-.Em ntpport
-and
-.Pf non\- Em ntpport
-may be specified. The
-.Em ntpport
-is considered more specific and is sorted later in the list.
-.El
-.It Xo unrestrict
-.Ar address
-.Ar mask
-.Ar flag
-.Op Ar flag
-.Xc
-Remove the specified flag(s) from the restrict list entry indicated
-by the
-.Ar address
-and
-.Ar mask
-arguments.
-.It Xo delrestrict
-.Ar address
-.Ar mask
-.Op Ar ntpport
-.Xc
-Delete the matching entry from the restrict list.
-.It monitor Ar yes|no
-Enable or disable the monitoring facility. Note that a
-.Em monitor Ar no
-command followed by a
-.Em monitor Ar yes
-command is a good way of resetting the packet counts.
-.It readkeys
-Cause the current set of authentication keys to be purged and a new set
-to be obtained by rereading the keys file (which must have been
-specified in the
-.Nm xntpd
-configuration file). This allows encryption keys to be changed without
-restarting the server.
-.It Xo trustkey
-.Ar keyid
-.Op Ar keyid
-.Op Ar keyid
-.Op Ar keyid
-.Xc
-Add one or more keys to the trusted key list. When authentication is
-enabled, peers whose time is to be trusted must be authenticated using a
-trusted key.
-.It Xo untrustkey
-.Ar keyid
-.Op Ar keyid  
-.Op Ar keyid  
-.Op Ar keyid  
-.Xc
-Remove one or more keys from the trusted key list.
-.It authinfo
-Return information concerning the authentication module, including
-known keys and counts of encryptions and decryptions which have been
-done.
-.It setprecision Ar precision_value
-Set the precision which the server advertises to the specified value.
-This should be a negative integer in the range -4 through -20.
-.It traps
-Display the traps set in the server. See the source listing for further
-information.
-.It Xo addtrap
-.Ar address
-.Op Ar port
-.Op Ar interface
-.Xc
-Set a trap for asynchronous messages. See the source listing for further
-information.
-.It Xo clrtrap
-.Ar address
-.Op Ar port
-.Op Ar interface
-.Xc
-Clear a trap for asynchronous messages. See the source listing for
-further information.
-.It reset Ar ...
-Clear the statistics counters in various modules of the server. See the

- * NTP uses two fixed point formats.  The first (l_fp) is the "long" format
- * and is 64 bits long with the decimal between bits 31 and 32.  This
- * is used for time stamps in the NTP packet header (in network byte
- * order) and for internal computations of offsets (in local host byte
- * order).  We use the same structure for both signed and unsigned values,
- * which is a big hack but saves rewriting all the operators twice.  Just
- * to confuse this, we also sometimes just carry the fractional part in
- * calculations, in both signed and unsigned forms.  Anyway, an l_fp looks
- * like:
- *
- *    0			  1		      2			  3
- *    0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

-WHICH NICE
-
-  HAVE_ATT_NICE     - Use att nice(priority_change)
-  HAVE_BSD_NICE     - Use bsd setprioirty(which, who, priority)
-  HAVE_NO_NICE      - Don't have (or use) either
-
-KERNEL MUCKING - If you porting to a new system see xntpd/ntp_unixclock.c and
-		 util/tickadj.c to see what these do. This is very system
-	         dependent stuff!!!
-
-  HAVE_LIBKVM       - Use libkvm to read kernal memory
-  HAVE_READKMEM     - Use read to read kernal memory
-  NOKMEM	    - Don't read kmem
-  HAVE_N_UN         - Have u_nn nlist struct.
-
-WHICH SETPGRP TO USE - Not needed if NTP_POSIX_SOURCE is defined since you
-		       better of setsid!
-
-  HAVE_ATT_SETPGRP  - setpgrp(void) instead of setpgrp(int, int)
-
-
-Signaled IO -  Signled IO defines.
-
-  HAVE_SIGNALED_IO  - Enable signaled io. Assumes you are going to use SIGIO
-		      for tty and udp io.
-  USE_UDP_SIGPOLL   - Use SIGPOLL on socket io. This assumes that the
-		      sockets routines are defined on top of streams.
-  USE_TTY_SIGPOLL   - Use SIGPOLL on tty io. This assumes streams.
-  UDP_BACKWARDS_SETOWN - SunOS 3.5 or Ultirx 2.0 system.
-
-
-WHICH TERMINAL MODEL TO USE - I would assume HAVE_TERMIOS if
-		      NTP_POSIX_SOURCE was set but can't.  The
-		      posix tty driver is too restrictive on most systems.
-		      It is defined if you define STREAMS.
-
-  We do not put these defines in the ntp_machine.h as some systems
-  offer multiple interfaces and refclock configuration likes to
-  peek into the configuration defines for tty model restrictions.
-  Thus all tty definitions should be in the files in the machines directory.
-
-  HAVE_TERMIOS      - Use POSIX termios.h
-  HAVE_SYSV_TTYS    - Use SYSV termio.h
-  HAVE_BSD_TTYS     - Use BSD stty.h
-
-THIS MAKES PORTS TO NEW SYSTEMS EASY - You only have to wory about
-		                       kernel mucking.
-
-  NTP_POSIX_SOURCE  - Use POSIX functions over bsd functions and att functions.
-		      This is NOT the same as _POSIX_SOURCE.
-		      It is much weaker!
-
-
-STEP SLEW OR TWO STEP - The Default is to step.
-
-  SLEWALWAYS  	    - setttimeofday can not be used to set the time of day at
-		      all.
-  STEP_SLEW 	    - setttimeofday can not set the seconds part of time
-		      time use setttimeofday to set the seconds part of the
-		      time and the slew the seconds.
-  FORCE_NTPDATE_STEP - even if SLEWALWAYS is defined, force a step of
-		      of the systemtime (via settimeofday()). Only takes
-		      affect if STEP_SLEW isn't defined.
-
-WHICH TIMEOFDAY()
-
-  SYSV_TIMEOFDAY    - [sg]ettimeofday(struct timeval *) as opposed to BSD
-                      [sg]ettimeofday(struct timeval *, struct timezone *)
-
-INFO ON NEW KERNEL PLL SYS CALLS
-
-  NTP_SYSCALLS_STD  - use the "normal" ones
-  NTP_SYSCALL_GET   - SYS_ntp_gettime id
-  NTP_SYSCALL_ADJ   - SYS_ntp_adjtime id
-  NTP_SYSCALLS_LIBC - ntp_adjtime() and ntp_gettime() are in libc.

-HOW TO GET IP INTERFACE INFORMATION
-
-  Some UNIX V.4 machines implement a sockets library on top of
-  streams. For these systems, you must use send the SIOCGIFCONF down
-  the stream in an I_STR ioctl. This ususally also implies
-  USE_STREAMS_DEVICE FOR IF_CONFIG. Dell UNIX is a notable exception.
-
-  STREAMS_TLI - use ioctl(I_STR) to implement ioctl(SIOCGIFCONF)
-
-WHAT DOES IOCTL(SIOCGIFCONF) RETURN IN THE BUFFER
-
-  UNIX V.4 machines implement a sockets library on top of streams.
-  When requesting the IP interface configuration with an ioctl(2) calll,
-  an array of ifreq structures are placed in the provided buffer.  Some
-  implementations also place the length of the buffer information in
-  the first integer position of the buffer.
-
-  SIZE_RETURNED_IN_BUFFER - size integer is in the buffer
-
-WILL IOCTL(SIOCGIFCONF) WORK ON A SOCKET
-
-  Some UNIX V.4 machines do not appear to support ioctl() requests for the
-  IP interface configuration on a socket.  They appear to require the use
-  of the streams device instead.
-
-  USE_STREAMS_DEVICE_FOR_IF_CONFIG - use the /dev/ip device for configuration
-
-MISC
-
-  USE_PROTOTYPES    - Prototype functions
-  DOSYNCTODR        - Resync TODR clock  every hour.
-  RETSIGTYPE        - Define signal function type.
-  NO_SIGNED_CHAR_DECL - No "signed char" see include/ntp.h
-  LOCK_PROCESS      - Have plock.
-  UDP_WILDCARD_DELIVERY
-		    - these systems deliver broadcast packets to the wildcard
-		      port instead to a port bound to the interface bound
-		      to the correct broadcast address - are these
-		      implementations broken or did the spec change ?
-
-DEFINITIONS FOR SYSTEM && PROCESSOR
-  STR_SYSTEM        - value of system variable
-  STR_PROCESSOR     - value of processor variable
-
-You could just put the defines on the DEFS line in machines/<os> file.
-I don't since there are lots of different types of compilers that a system might
-have, some that can do proto typing and others that cannot on the same system.
-I get a chance to twiddle some of the configuration parameters at compile
-time based on compiler/machine combinations by using this include file.
-See convex, aix and sun configurations see how complex it get.
-
-Note that it _is_ considered reasonable to add some system-specific defines
-to the machine/<os> file if it would be too inconvenient to puzzle them out
-in this file.

- * where the fields are (note that the client sends requests, the server
- * responses):
- *
- * Response Bit:  This packet is a response (if clear, packet is a request).
- *
- * More Bit:	Set for all packets but the last in a response which
- *		requires more than one packet.
- *
- * Version Number: 2 for current version
- *
- * Mode:	Always 7
- *
- * Authenticated bit: If set, this packet is authenticated.
- *
- * Sequence number: For a multipacket response, contains the sequence
- *		number of this packet.  0 is the first in the sequence,
- *		127 (or less) is the last.  The More Bit must be set in
- *		all packets but the last.
- *
- * Implementation number: The number of the implementation this request code
- *		is defined by.  An implementation number of zero is used
- *		for requst codes/data formats which all implementations
- *		agree on.  Implementation number 255 is reserved (for
- *		extensions, in case we run out).
- *
- * Request code: An implementation-specific code which specifies the
- *		operation to be (which has been) performed and/or the
- *		format and semantics of the data included in the packet.
- *
- * Err:		Must be 0 for a request.  For a response, holds an error
- *		code relating to the request.  If nonzero, the operation
- *		requested wasn't performed.
- *
- *		0 - no error
- *		1 - incompatable implementation number
- *		2 - unimplemented request code
- *		3 - format error (wrong data items, data size, packet size etc.)
- *		4 - no data available (e.g. request for details on unknown peer)
- *		5-6 I don't know
- *		7 - authentication failure (i.e. permission denied)
- *
- * Number of data items: number of data items in packet.  0 to 500
- *
- * MBZ:		A reserved data field, must be zero in requests and responses.
- *
- * Size of data item: size of each data item in packet.  0 to 500
- *
- * Data:	Variable sized area containing request/response data.  For
- *		requests and responses the size in octets must be greater
- *		than or equal to the product of the number of data items
- *		and the size of a data item.  For requests the data area
- *		must be exactly 40 octets in length.  For responses the
- *		data area may be any length between 0 and 500 octets
- *		inclusive.
- *
- * Message Authentication Code: Same as NTP spec, in definition and function.
- *		May optionally be included in requests which require
- *		authentication, is never included in responses.
- *
- * The version number, mode and keyid have the same function and are
- * in the same location as a standard NTP packet.  The request packet
- * is the same size as a standard NTP packet to ease receive buffer
- * management, and to allow the same encryption procedure to be used
- * both on mode 7 and standard NTP packets.  The mac is included when
- * it is required that a request be authenticated, the keyid should be
- * zero in requests in which the mac is not included.
- *
- * The data format depends on the implementation number/request code pair
- * and whether the packet is a request or a response.  The only requirement
- * is that data items start in the octet immediately following the size
- * word and that data items be concatenated without padding between (i.e.
- * if the data area is larger than data_items*size, all padding is at
- * the end).  Padding is ignored, other than for encryption purposes.
- * Implementations using encryption might want to include a time stamp
- * or other data in the request packet padding.  The key used for requests
- * is implementation defined, but key 15 is suggested as a default.

- * SHIFT_KG and SHIFT_KF establish the damping of the PLL and are chosen
- * for a slightly underdamped convergence characteristic.
- *
- * MAXTC establishes the maximum time constant of the PLL. With the

- * clamped to the bound and operation proceeds accordingly. In practice,
- * this can occur only if something has failed or is operating out of
- * tolerance, but otherwise the PLL continues to operate in a stable

- * MAXPHASE must be set greater than or equal to CLOCK.MAX (128 ms), as
- * defined in the NTP specification. CLOCK.MAX establishes the maximum
- * time offset allowed before the system time is reset, rather than
- * incrementally adjusted. Here, the maximum offset is clamped to
- * MAXPHASE only in order to prevent overflow errors due to defective
- * protocol implementations.
- *
- * MAXFREQ is the maximum frequency tolerance of the CPU clock
- * oscillator plus the maximum slew rate allowed by the protocol. It
- * should be set to at least the frequency tolerance of the oscillator
- * plus 100 ppm for vernier frequency adjustments. If the kernel
- * PPS discipline code is configured (PPS_SYNC), the oscillator time and
- * frequency are disciplined to an external source, presumably with
- * negligible time and frequency error relative to UTC, and MAXFREQ can
- * be reduced.

- * kernel PPS discipline code is configured (PPS_SYNC).

-Precision Time and Frequency Synchronization Using Modified Kernels
-
-1. Introduction
-
-This memo describes replacements for certain SunOS and Ultrix kernel
-routines that manage the system clock and timer functions. They provide
-improved accuracy and stability through the use of a disciplined clock
-interface for use with the Network Time Protocol (NTP) or similar time-
-synchronization protocol. In addition, for certain models of the
-DECstation 5000 product line, the new routines provide improved
-precision to +-1 microsecond (us) (SunOS 4.1.1 already does provide
-precision to +-1 us). The current public NTP distribution cooperates
-with these kernel routines to provide synchronization in principle to
-within a microsecond, but in practice this is limited by the short-term
-stability of the oscillator that drives the timer interrupt.
-
-This memo describes the principles behind the design and operation of
-the software. There are two versions of the software, one that operates
-with the SunOS 4.1.1 kernel and the other that operates with the Ultrix
-4.2a kernel (and probably the 4.3 kernel, although this has not been
-tested). A detailed description of the variables and algorithms is given
-in the hope that similar improvements can be incorporated in Unix
-kernels for other machines. The software itself is not included in this
-memo, since it involves licensed code. Detailed instructions on where to
-obtain it for either SunOS or Ultrix will be given separately.
-
-The principle function added to the SunOS and Ultrix kernels is to
-change the way the system clock is controlled, in order to provide
-precision time and frequency adjustments. Another function utilizes an
-undocumented counter in the DECstation hardware to provide precise time
-to the microsecond. This function can be used only with the DECstation
-5000/240 and possibly others that use the same input/output chipset.
-
-2. Design Principles
-
-In order to understand how these routines work, it is useful to consider
-how most Unix systems maintain the system clock. In the original design
-a hardware timer interrupts the kernel at some fixed rate, such as 100
-Hz in the SunOS kernel and 256 Hz in the Ultrix kernel. Since 256 does
-not evenly divide the second in microseconds, the kernel inserts 64 us
-once each second so that the system clock stays in step with real time.
-The time returned by the gettimeofday() routine is thus characterized by
-255 advances of 3906 us plus one of 3970 us.
-
-Also in the original design it is possible to slew the system clock to a
-new offset using the adjtime() system call. To do this the clock
-frequency is changed by adding or subtracting a fixed amount (tickadj)
-at each timer interrupt (tick) for a calculated number of ticks. Since
-this calculation involves dividing the requested offset by tickadj, it
-is possible to slew to a new offset with a precision only of tickadj,
-which is usually in the neighborhood of 5 us, but sometimes much higher.
-
-In order to maintain the system clock within specified bounds with this
-scheme, it is necessary to call adjtime() on a regular basis. For
-instance, let the bound be set at 100 us, which is a reasonable value
-for NTP-synchronized hosts on a local network, and let the onboard
-oscillator tolerance be 100 ppm, which is a reasonably conservative
-assumption. This requires that adjtime() be called at intervals not
-exceeding 1 second (s), which is in fact what the unmodified NTP
-software daemon does.
-
-In the modified kernel routines this scheme is replaced by another that
-extends the low-order bits of the system clock to provide very precise
-clock adjustments. At each timer interrupt a precisely calibrated time
-adjustment is added to the composite time value and overflows handled as
-required. The quantity to add is computed from the adjtime() call and,
-in addition a frequency adjustment, which is automatically calculated
-from previous time adjustments. This implementation operates as an
-adaptive-parameter, first-order, type-II, phase-lock loop (PLL), which
-in principle provides precision control of the system clock phase to
-within +-1 us and frequency to within +-5 nanoseconds (ns) per day.
-
-This PLL model is identical to the one implemented in NTP, except that
-in NTP the software daemon has to simulate the PLL using only the
-original adjtime() system call. The daemon is considerably complicated
-by the need to parcel time adjustments at frequent intervals in order to
-maintain the accuracy to specified bounds. The kernel routines do this
-directly, allowing vast gobs of ugly daemon code to be avoided at the
-expense of only a small amount of new code in the kernel. In fact, the
-amount of code added to the kernel for the new scheme is about the
-amount removed for the old scheme. The new adjtime() routine needs to be
-called only as each new time update is determined, which in NTP occurs
-at intervals of from 64 s to 1024 s. In addition, doing the frequency
-correction in the kernel means that the system time runs true even if
-the daemon were to cease operation or the network paths to the primary
-reference source fail.
-
-Note that the degree to which the adjtime() adjustment can be made is
-limited to a specific maximum value, presently +-128 milliseconds (ms),
-in order to achieve microsecond resolution. It is the intent in the
-design that settimeofday() be used for changes in system time greater
-than +-128 ms. It has been the Internet experience that the need to
-change the system time in increments greater than +-128 milliseconds is
-extremely rare and is usually associated with a hardware or software
-malfunction. Nevertheless, the limit applies to each adjtime() call and
-it is possible, but not recommended, that this routine is called at
-intervals smaller than 64 seconds, which is the NTP lower limit.
-
-For the most accurate and stable operation, adjtime() should be called
-at specified intervals; however, the PLL is quite forgiving and neither
-moderate loss of updates nor variations in the length of the interval is
-serious. The current engineering parameters have been optimized for
-intervals not greater than about 64 s. For larger intervals the PLL time
-constant can be adjusted to optimize the dynamic response up to
-intervals of 1024 s. Normally, this is automatically done by NTP. In any
-case, if updates are suspended, the PLL coasts at the frequency last
-determinated, which usually results in errors increasing only to a few
-tens of milliseconds over a day.
-
-The new code needs to know the initial frequency offset and time
-constant for the PLL, and the daemon needs to know the current frequency
-offset computed by the kernel for monitoring purposes. This is provided
-by a small change in the second argument of the kernel adjtime() calling
-sequence, which is documented later in this memo. Ordinarily, only the
-daemon will call the adjtime() routine, so the modified calling sequence
-is easily accommodated. Other than this change, the operation of
-adjtime() is transparent to the original.
-
-In the DECstation 5000/240 and possibly other models there happens to be
-an undocumented hardware register that counts system bus cycles at a
-rate of 25 MHz. The new kernel routines test for the CPU type and, in
-the case of the '240, use this register to interpolate system time
-between hardware timer interrupts. This results in a precision of +-1 us
-for all time values obtained via the gettimeofday() system call. This
-routine calls the kernel routine microtime(), which returns the actual
-interpolated value, but does not change the kernel time variable.
-Therefore, other kernel routines that access the kernel time variable
-directly and do not call either gettimeofday() or microtime() will
-continue their present behavior.
-
-The new kernel routines include provisions for error statistics (maximum
-error and estimated error), leap seconds and system clock status. These
-are intended to support applications that need such things; however,
-there are no applications other than the time-synchronization daemon
-itself that presently use them. At issue is the manner in which these
-data can be provided to application clients, such as new system calls
-and data interfaces. While a proposed interface is described later in
-this memo, it has not yet been implemented. This is an area for further
-study.
-
-While any time-synchronization daemon can in principle be modified to
-use the new code, the most likely will be users of the xntp3
-distribution of NTP. The code in the xntp3 distribution determines
-whether the new kernel code is in use and automatically reconfigures as
-required. When the new code is in use, the daemon reads the frequency
-offset from a file and provides it and the initial time constant via
-adjtime(). In subsequent calls to adjtime(), only the time adjustment
-and time constant are affected. The daemon reads the frequency from the
-kernel (returned as the second argument of adjtime()) at intervals of
-one hour and writes it to the file.
-
-3. Technical Description
-
-Following is a technical description of how the new scheme works in
-terms of the variables and algorithms involved. These components are
-discussed as a distinct entity and do not involve coding details
-specific to the Ultrix kernel. The algorithms involve only minor changes
-to the system clock and interval timer routines, but do not in
-themselves provide a conduit for application programs to learn the
-system clock status or statistics of the time-synchronization process.
-In a later section a number of new system calls are proposed to do this,
-along with an interface specification.
-
-The new scheme works like the companion simulator called kern.c and
-included in this directory. This stand-alone simulator includes code
-fragments identical to those in the modified kernel routines and
-operates in the same way. The system clock is implemented in the kernel
-using a set of variables and algorithms defined below and in the
-simulator. The algorithms are driven by explicit calls from the
-synchronization protocol as each time update is computed. The clock is
-read and set using the gettimeofday() and settimeofday() system calls,
-which operate in the same way as the originals, but return a status word
-describing the state of the system clock.
-
-Once the system clock has been set, the adjtime() system call is used to
-provide periodic updates including the time offset and possibly
-frequency offset and time constant. With NTP this occurs at intervals of
-from 64 s to 1024 s, deending on the time constant value. The kernel
-implements an adaptive-parameter, first-order, type-II, phase-lock loop
-(PLL) in order to integrate this offset into the phase and frequency of
-the system clock. The kernel keeps track of the time of the last update
-and adjusts the maximum error to grow by an amount equal to the
-oscillator frequency tolerance times the elapsed time since the last
-update.
-
-Occasionally, it is necessary to adjust the PLL parameters in response
-to environmental conditions, such as leap-second warning and oscillator
-stability observations. While the interface to do this has not yet been
-implemented, proposals to to that are included in a later section. A
-system call (setloop()) is used on such occasions to communicate these
-data. In addition, a system call (getloop())) is used to extract these
-data from the kernel for monitoring purposes.
-
-All programs utilize the system clock status variable time_status, which
-records whether the clock is synchronized, waiting for a leap second,
-etc. The value of this variable is returned by each system call. It can
-be set explicitly by the setloop() system call and implicitly by the
-settimeofday() system call and in the timer-interrupt routine. Values
-presently defined in the header file timex.h are as follows:
-
-int time_status = TIME_BAD;     /* clock synchronization status */
-
-#define TIME_UNS 0      /* unspecified or unknown */
-#define TIME_OK 1       /* operation succeeded */
-#define TIME_INS 1      /* insert leap second at end of current day */
-#define TIME_DEL 2      /* delete leap second at end of current day */
-#define TIME_OOP 3      /* leap second in progress */
-#define TIME_BAD 4      /* system clock is not synchronized */
-#define TIME_ADR -1     /* operation failed: invalid address */
-#define TIME_VAL -2     /* operation failed: invalid argument */
-#define TIME_PRV -3     /* operation failed: priviledged operation */
-
-In case of a negative result code, the operation has failed; however,
-some variables may have been modified before the error was detected.
-Note that the new system calls never return a value of zero, so it is
-possible to determine whether the old routines or the new ones are in
-use. The syntax of the modified adjtime() is as follows:
-
-/*
- * adjtime - adjuts system time
- */
-#include <sys/timex.h>
-
-int gettimexofday(tp, fiddle)
-
-struct timeval *tp;     /* system time adjustment*/
-struct timeval *fiddle; /* sneak path */
-
-On entry the "timeval" sneak path is coded:
-
-struct timeval {
-        long tv_sec = time_constant;    /* time constant */
-        long tv_usec = time_freq;       /* new frequency offset */
-}
-
-However, the sneak is ignored if fiddle is the null pointer and the new
-frequency offset is ignored if zero.
-
-The value returned on exit is the system clock status defined above. The
-"timeval" sneak path is modified as follows:
-
-struct timeval {
-        long tv_sec = time_precision;   /* system clock precision */
-        long tv_usec = time_freq;       /* current frequency offset */
-}
-
-3.1. Kernel Variables
-
-The following variables are used by the new code:
-
-long time_offset = 0;           /* time adjustment (us) */
-
-This variable is used by the PLL to adjust the system time in small
-increments. It is scaled by (1 << SHIFT_UPDATE) in binary microseconds.
-The maximum value that can be represented is about +-130 ms and the
-minimum value or precision is about one nanosecond.
-
-long time_constant = SHIFT_TAU; /* pll time constant */
-
-This variable determines the bandwidth or "stiffness" of the PLL. It is
-used as a shift, with the effective value in positive powers of two. The
-optimum value for this variable is equal to 1/64 times the update
-interval. The default value SHIFT_TAU (0) corresponds to a PLL time
-constant of about one hour or an update interval of about one minute,
-which is appropriate for typical uncompensated quartz oscillators used
-in most computing equipment. Values larger than four are not useful,
-unless the local clock timebase is derived from a precision oscillator.
-
-long time_tolerance = MAXFREQ;  /* frequency tolerance (ppm) */
-
-This variable represents the maximum frequency error or tolerance of the
-particular platform and is a property of the architecture. It is
-expressed as a positive number greater than zero in parts-per-million
-(ppm). The default MAXFREQ (100) is appropriate for conventional
-workstations.
-
-long time_precision = 1000000 / HZ; /* clock precision (us) */
-
-This variable represents the maximum error in reading the system clock.
-It is expressed as a positive number greater than zero in microseconds
-and is usually based on the number of microseconds between timer
-interrupts, in the case of the Ultrix kernel, 3906. However, in cases
-where the time can be interpolated between timer interrupts with
-microsecond resolution, the precision is specified as 1. This variable
-is computed by the kernel for use by the time-synchronization daemon,
-but is otherwise not used by the kernel.
-
-struct timeval time_maxerror;   /* maximum error */
-
-This variable represents the maximum error, expressed as a Unix timeval,
-of the system clock. For NTP, it is computed as the synchronization
-distance, which is equal to one-half the root delay plus the root
-dispersion. It is increased by a small amount (time_tolerance) each
-second to reflect the clock frequency tolerance. This variable is
-computed by the time-synchronization daemon and the kernel for use by
-the application program, but is otherwise not used by the kernel.
-
-struct timeval time_esterror;   /* estimated error */
-
-This variable represents the best estimate of the actual error,
-expressed as a Unix timeval, of the system clock based on its past
-behavior, together with observations of multiple clocks within the peer
-group. This variable is computed by the time-synchronization daemon for
-use by the application program, but is otherwise not used by the kernel.
-
-The PLL itself is controlled by the following variables:
-
-long time_phase = 0;            /* phase offset (scaled us) */
-long time_freq = 0;             /* frequency offset (scaled ppm) */long
-time_adj = 0;                   /* tick adjust (scaled 1 / HZ) */
-
-These variables control the phase increment and the frequency increment
-of the system clock at each tick of the clock. The time_phase variable
-is scaled by (1 << SHIFT_SCALE) in binary microseconds, giving a minimum
-value (time resolution) of 9.3e-10 us. The time_freq variable is scaled
-by (1 << SHIFT_KF) in parts-per-million (ppm), giving it a maximum value
-of about +-130 ppm and a minimum value (frequency resolution) of 6e-8
-ppm. The time_adj variable is the actual phase increment in scaled
-microseconds to add to time_phase once each tick. It is computed from
-time_phase and time_freq once per second.
-
-long time_reftime = 0;          /* time at last adjustment (s) */
-
-This variable is the second's portion of the system time on the last
-call to adjtime(). It is used to adjust the time_freq variable as the
-time since the last update increases.
-
-The HZ define establishes the timer interrupt frequency, 256 Hz for the
-Ultrix kernel and 100 Hz for the SunOS kernel. The SHIFT_HZ define
-expresses the same value as the nearest power of two in order to avoid
-hardware multiply operations. These are the only parameters that need to
-be changed for different timer interrupt rates.
-
-#define HZ 256                  /* timer interrupt frequency (Hz) */
-#define SHIFT_HZ 8              /* log2(HZ) */
-
-The following defines establish the engineering parameters of the PLL
-model. They are chosen for an initial convergence time of about an hour,
-an overshoot of about seven percent and a final convergence time of
-several hours, depending on initial frequency error.
-
-#define SHIFT_KG 10             /* shift for phase increment */
-#define SHIFT_KF 24             /* shift for frequency increment */
-#define SHIFT_TAU 0             /* default time constant (shift) */
-
-The SHIFT_SCALE define establishes the decimal point on the time_phase
-variable which serves as a an extension to the low-order bits of the
-system clock variable. The SHIFT_UPDATE define establishes the decimal
-point of the phase portion of the adjtime() update. The FINEUSEC define
-represents 1 us in scaled units.
-
-#define SHIFT_SCALE 28          /* shift for scale factor */
-#define SHIFT_UPDATE 14         /* shift for offset scale factor */
-#define FINEUSEC (1 << SHIFT_SCALE) /* 1 us in scaled units */
-
-The FINETUNE define represents the residual, in ppm, to be added to the
-system clock variable in addition to the integral 1-us value given by
-tick. This allows a systematic frequency offset in cases where the timer
-interrupt frequency does not exactly divide the second in microseconds.
-
-#define FINETUNE (1000000 - (1000000 / HZ) * HZ) /* frequency adjustment
-                                 * for non-isochronous HZ (ppm) */
-
-The following four defines establish the performance envelope of the
-PLL, one to bound the maximum phase error, another to bound the maximum
-frequency error and the last two to bound the minimum and maximum time
-between updates. The intent of these bounds is to force the PLL to
-operate within predefined limits in order to conform to the correctness
-models assumed by time-synchronization protocols like NTP and DTSS. An
-excursion which exceeds these bounds is clamped to the bound and
-operation proceeds accordingly. In practice, this can occur only if
-something has failed or is operating out of tolerance, but otherwise the
-PLL continues to operate in a stable mode. Note that the MAXPHASE define
-conforms to the maximum offset allowed in NTP before the system time is
-reset, rather than incrementally adjusted.
-
-#define MAXPHASE 128000         /* max phase error (us) */
-#define MINSEC 64               /* min interval between updates (s) */
-#define MAXFREQ 100             /* max frequency error (ppm) */
-#define MAXSEC 1024             /* max interval between updates (s) */
-
-3.2. Code Segments
-
-The code segments illustrated in the simulator should make clear the
-operations at various points in the code. These segments are not derived
-from any licensed code. The hardupdate() fragment is called by adjtime()
-to update the system clock phase and frequency. This is an
-implementation of an adaptive-parameter, first-order, type-II phase-lock
-loop. Note that the time constant is in units of powers of two, so that
-multiplies can be done by simple shifts. The phase variable is computed
-as the offset multiplied by the time constant. Then, the time since the
-last update is computed and clamped to a maximum (for robustness) and to
-zero if initializing. The offset is multiplied (sorry about the ugly
-multiply) by the result and by the square of the time constant and then
-added to the frequency variable. Finally, the frequency variable is
-clamped not to exceed the tolerance. Note that all shifts are assumed to
-be positive and that a shift of a signed quantity to the right requires
-a litle dance.
-
-With the defines given, the maximum time offset is determined by the
-size in bits of the long type (32) less the SHIFT_UPDATE (14) scale
-factor or 18 bits (signed). The scale factor is chosen so that there is
-no loss of significance in later steps, which may involve a right shift
-up to 14 bits. This results in a maximum offset of about +-130 ms. Since
-the time_constant must be greater than or equal to zero, the maximum
-frequency offset is determined by the SHIFT_KF (24) scale factor, or
-about +-130 ppm. In the addition step the value of offset * mtemp is
-represented in 18 + 10 = 28 bits, which will not overflow a long add.
-There could be a loss of precision due to the right shift of up to eight
-bits, since time_constant is bounded at four. This results in a net
-worst-case frequency error of about 2^-16 us or well down into the
-oscillator phase noise. While the time_offset value is assumed checked
-before entry, the time_phase variable is an accumulator, so is clamped
-to the tolerance on every call. This helps to damp transients before the
-oscillator frequency has been determined, as well as to satisfy the
-correctness assertions if the time-synchronization protocol comes
-unstuck.
-
-The hardclock() fragment is inserted in the hardware timer interrupt
-routine at the point the system clock is to be incremented. The phase
-adjustment (time_adj) is added to the clock phase (time_phase) and
-tested for overflow of the microsecond. If an overflow occurs, the
-microsecond (tick) in incremented or decremented.
-
-The second_overflow() fragment is inserted at the point where the
-microseconds field of the system time variable is being checked for
-overflow. On rollover of the second the maximum error is increased by
-the tolerance. The time offset is divided by the phase weight (SHIFT_KG)
-and time constant. The time offset is then reduced by the result and the
-result is scaled and becomes the value of the phase adjustment. The
-phase adjustment is then corrected for the calculated frequency offset
-and a fixed offset FINETUNE which is a property of the architecture. On
-rollover of the day the leap-warning indicator is checked and the
-apparent time adjusted +-1 s accordingly. The gettimeofday() routine
-insures that the reported time is always monotonically increasing.
-
-The simulator can be used to check the loop operation over the design
-range of +-128 ms in time error and +-100 ppm in frequency error. This
-confirms that no overflows occur and that the loop initially converges
-in about 50-60 minutes for timer interrupt rates from 50 Hz to 1024 Hz.
-The loop has a normal overshoot of about seven percent and a final
-convergence time of several hours, depending on the initional frequency
-error.
-
-3.3. Leap Seconds
-
-The leap-warning condition is determined by the synchronization protocol
-(if remotely synchronized), by the timecode receiver (if available), or
-by the operator (if awake). The time_status value must be set on the day
-the leap event is to occur (30 June or 31 December) and is automatically
-reset after the event. If the value is TIME_DEL, the kernel adds one
-second to the system time immediately following second 23:59:58 and
-resets time_status to TIME_OK. If the value is TIME_INS, the kernel
-subtracts one second from the system time immediately following second
-23:59:59 and resets time_status to TIME_OOP, in effect causing system
-time to repeat second 59. Immediately following the repeated second, the
-kernel resets time_status to TIME_OK.
-
-Depending upon the system call implementation, the reported time during
-a leap second may repeat (with a return code set to advertise that fact)
-or be monotonically adjusted until system time "catches up" to reported
-time. With the latter scheme the reported time will be correct before
-and after the leap second, but freeze or slowly advance during the leap
-second itself. However, Most programs will probably use the ctime()
-library routine to convert from timeval (seconds, microseconds) format
-to tm format (seconds, minutes,...). If this routine is modified to
-inspect the return code of the gettimeofday() routine, it could simply
-report the leap second as second 60.
-
-To determine local midnight without fuss, the kernel simply finds the
-residue of the time.tv_sec value mod 86,400, but this requires a messy
-divide. Probably a better way to do this is to initialize an auxiliary
-counter in the settimeofday() routine using an ugly divide and increment
-the counter at the same time the time.tv_sec is incremented in the timer
-interrupt routine. For future embellishment.
-
-4. Proposed Application Program Interface
-
-Most programs read the system clock using the gettimeofday() system
-call, which returns the system time and time-zone data. In the modified
-5000/240 kernel, the gettimeofday() routine calls the microtime()
-routine, which interpolates between hardware timer interrupts to a
-precision of +-1 microsecond. However, the synchronization protocol
-provides additional information that will be of interest in many
-applications. For some applications it is necessary to know the maximum
-error of the reported time due to all causes, including those due to the
-system clock reading error, oscillator frequency error and accumulated
-errors due to intervening time servers on the path to a primary
-reference source. However, for those protocols that adjust the system
-clock frequency as well as the time offset, the errors expected in
-actual use will almost always be much less than the maximum error.
-Therefore, it is useful to report the estimated error, as well as the
-maximum error.
-
-It does not seem useful to provide additional details private to the
-kernel and synchronization protocol, such as stratum, reference
-identifier, reference timestamp and so forth. It would in principle be
-possible for the application to independently evaluate the quality of
-time and project into the future how long this time might be "valid."
-However, to do that properly would duplicate the functionality of the
-synchronization protocol and require knowledge of many mundane details
-of the platform architecture, such as the tick value, reachability
-status and related variables. Therefore, the application interface does
-not reveal anything except the time, timezone and error data.
-
-With respect to NTP, the data maintained by the protocol include the
-roundtrip delay and total dispersion to the source of synchronization.
-In terms of the above, the maximum error is computed as half the delay
-plus the dispersion, while the estimated error is equal to the
-dispersion. These are reported in timeval structures. A new system call
-is proposed that includes all the data in the gettimeofday() plus the
-two new timeval structures.
-
-The proposed interface involves modifications to the gettimeofday(),
-settimeofday() and adjtime() system calls, as well as new system calls
-to get and set various system parameters. In order to minimize
-confusion, by convention the new system calls are named with an "x"
-following the "time"; e.g., adjtime() becomes adjtimex(). The operation
-of the modified gettimexofday(), settimexofday() and adjtimex() system
-calls is identical to that of their prototypes, except for the error
-quantities and certain other side effects, as documented below. By
-convention, a NULL pointer can be used in place of any argument, in
-which case the argument is ignored.
-
-The synchronization protocol daemon needs to set and adjust the system
-clock and certain other kernel variables. It needs to read these
-variables for monitoring purposes as well. The present list of these
-include a subset of the variables defined previously:
-
-long time_precision
-long time_timeconstant
-long time_tolerance
-long time_freq
-long time_status
-
-/*
- * gettimexofday, settimexofday - get/set date and time
- */
-#include <sys/timex.h>
-
-int gettimexofday(tp, tzp, tmaxp, testp)
-
-struct timeval *tp;     /* system time */
-struct timezone *tzp;   /* timezone */
-struct timeval *tmaxp;  /* maximum error */
-struct timeval *testp;  /* estimated error */
-
-The settimeofday() syntax is identical. Note that a call to
-settimexofday() automatically results in the system being declared
-unsynchronized (TIME_BAD return code), since the synchronization
-condition can only be achieved by the synchronization daemon using an
-internal or external primary reference source and the adjtimex() system
-call.
-
-/*
- * adjtimex - adjust system time
- */
-#include <sys/timex.h>
-
-int adjtimex(tp, tzp, freq, tc)
-
-struct timeval *tp;     /* system time */
-struct timezone *tzp;   /* timezone */
-long freq;              /* frequency adjustment */
-long tc;                /* time constant */
-
-/*
- * getloop, setloop - get/set kernel time variables
- */
-#include <sys/timex.h>
-
-int getloop(code, argp)
-
-int code;               /* operation code */
-long *argp;             /* argument pointer */
-
-The paticular kernal variables affected by these routines are selected
-by the operation code. Values presently defined in the header file
-timex.h are as follows:
-
-#define TIME_PREC 1     /* precision (log2(sec)) */
-#define TIME_TCON 2     /* time constant (log2(sec) */
-#define TIME_FREQ 3     /* frequency tolerance  */
-#define TIME_FREQ 4     /* frequency offset (scaled) */
-#define TIME_STAT 5     /* status (see return codes) */
-
-The getloop() syntax is identical.
-
-Comments welcome, but very little support is available:

-PARSE reference clock driver:
-
-This directory contains the files making up the parser for
-the parse refclock driver. For reasonably sane clocks this refclock
-drivers allows a refclock implementation by just providing a
-conversion routine and the appropriate NTP parameters. Refclock
-support can run as low a 3k code with the parse refclock driver.
-
-The modules in here are designed to live in two worlds. In userlevel
-as part of the xntp daemon and in kernel land as part of a STREAMS module
-or, if someone gets to it, as part of a line discipline. Currently only
-SunOS4.x/SunOS5.x STREAMS are supported (volunteers for other vendors like HP?).
-This structure means, that refclock_parse can work with or without kernel
-support. Kernelsupport increases accuracy tremendingly. The current restriction
-of the parse driver is that it only supports SYSV type ttys and that kernel
-support is only available for Suns right now.
-
-Three kernel modules are part of this directory. These work only on
-SunOS (SunOS4 and SunOS5 (not fully tested!)).
-
-	SunOS4 (aka Solaris 1.x):
-		parsestreams.o	- standard parse module for SunOS 4
-		mparsestreams.o - parse module for SunOS 4 with better
-				  clock reading code (assembler)
-
-		Both modules can be loaded via modload <modulename>.
-
-	SunOS5 (aka Solaris 2.x):
-		parse		- auto loadable streams module
-				  (not fully tested - don't kill me if
-				   it kills you machine)
-
-		To install just drop "parse" into /kernel/strmod and
-		start the daemon (SunOS5 will do the rest).
-
-The structure of the parse reference clock driver is as follows:
-
-	xntpd	- contains NTP implementation and calls a reference clock
-		  127.127.8.x which is implemented by
-		refclock_parse.c
-		  - which contains several refclock decriptions. These are
-		    selected by the x part of the refclock address.
-		    The lower two bits specify the device to use. Thus the
-		    value (x % 4) determines the device to open
-		    (/dev/refclock-0 - /dev/refclock-3).
-
-		    The kind of clock is selected by bits 2-6. This parameter
-		    selects the clock type which deterimines how I/O is done,
-		    the tty parameters and the NTP parameters.
-
-		    refclock_parse operates on an abstract reference clock
-		    that delivers time stamps and stati. Offsets and sychron-
-		    isation information is derived from this data and passed
-		    on to refclock_receive of xntp which uses that data for
-		    syncronisation.
-
-		    The abstract reference clock is generated by the parse*
-		    routines. They parse the incoming data stream from the
-		    clock and convert it to the appropriate time stamps.
-		    The data is also mapped int the abstract clock states
-		    	POWERUP - clock has no valid phase and time code
-				  information
-
-			NOSYNC	- Time code is not confirmed, phase is probably
-				  ok.
-			SYNC	- Time code and phase are correct.
-
-		    A clock is trusted for a certain time (type parameter) when
-		    it leaves the SYNC state. This is derived from the
-		    observation that quite a few clocks can still generate good
-		    time code information when losing contact to their
-		    synchronisation source. When the clock does not reagain
-		    synchronisation in that trust period it will be deemed
-		    unsynchronised until it regains synchronisation. The same
-		    will happen if xntp sees the clock unsynchronised at
-		    startup.
-
-		    The upper bit of x specifies that all samples delivered
-		    from the clock should be used to discipline the NTP
-		    loppfilter. For clock with accurate once a second time
-		    information this means big improvements for time keeping.
-		    A prerequisite for passing on the time stamps to
-		    the loopfilter is, that the clock is in synchronised state.
-
-	   parse.c  These are the general routines to parse the incoming data
-		    stream. Usually these routines should not require
-		    modification.
-
-	   clk_*.c  These files hole the conversion code for the time stamps
-		    and the description how the time code can be parsed and
-		    where the time stamps are to be taken.
-		    If you want to add a new clock type this is the file
-		    you need to write in addition to mention it in
-		    parse_conf.c and setting up the NTP and TTY parameters
-		    in refclock_parse.c.
-
-Further information can be found in parse/README.parse and the various source
-files.

-Here is an attempt to sketch out what you need to do in order to
-add another clock to the parse driver:
-
-Prerequisites:
-- Does the system you want the clock connect to have
-  termio.h or termios.h ? (You need that for the parse driver)
-
-What to do:
-
-Make a conversion module (parse/clk_*.c)
-
-- What ist the time code format ?
-  - find year, month, day, hour, minute, second, status (synchronised or
-    not), possibly time zone information (you need to give the offset to UTC)
-    You will have to convert the data from a string into a struct clocktime:
-      struct clocktime                /* clock time broken up from time code */
-      {

-     Conversion is usually simple and straight forward. For the flags following
-     values can be OR'ed together:
-
-     PARSEB_ANNOUNCE           switch time zone warning (informational only)
-     PARSEB_POWERUP            no synchronisation - clock confused (must set then)
-     PARSEB_NOSYNC             timecode currently not confirmed (must set then)
-                               usually on reception error when there is still a
-                               chance the the generated time is still ok.
-
-     PARSEB_DST                DST in effect (informational only)
-     PARSEB_UTC                timecode contains UTC time (informational only)
-     PARSEB_LEAPADD            LEAP addition warning (prior to leap happening - must set when imminent)
-			       also used for time code that do not encode the
-			       direction (as this is currently the default).
-     PARSEB_LEAPDEL            LEAP deletion warning (prior to leap happening - must set when imminent)
-     PARSEB_ALTERNATE          backup transmitter (informational only)
-     PARSEB_POSITION           geographic position available (informational only)
-     PARSEB_LEAPSECOND         actual leap second (this time code is the leap
-                               second - informational only)
-     
-     These are feature flags denoting items that are supported by the clock:
-     PARSEB_S_LEAP             supports LEAP - might set PARSEB_LEAP
-     PARSEB_S_ANTENNA          supports ANTENNA - might set PARSEB_ALTERNATE
-     PARSEB_S_PPS              supports PPS time stamping
-     PARSEB_S_POSITION         supports position information (GPS)
-
-     If the utctime field is non zero this value will be take as
-     time code value. This allows for conversion routines that
-     already have the utc time value. The utctime field gives the seconds
-     since Jan 1st 1970, 0:00:00. The useconds field gives the respective
-     usec value. The fields for date and time (down to second resolution)
-     will be ignored.
-
-     Conversion is done in the cvt_* routine in parse/clk_*.c files. look in
-     them for examples. The basic structure is:
-
-     struct clockformat <yourclock>_format = {
-       lots of fields for you to fill out (see below)
-     };
-
-     static cvt_<yourclock>()
-       ...
-     {
-       if (<I do not recognize my time code>) {
-         return CVT_NONE;
-       } else {
-         if (<conversion into clockformat is ok>) {
-           <set all necessary flags>;
-           return CVT_OK;
-         } else {
-           return CVT_FAIL|CVT_BADFMT;
-         }
-       }
-
-     The struct clockformat is the interface to the rest of the parse
-     driver - it holds all information necessary for finding the
-     clock message and doing the appropriate time stamping.
-
-struct clockformat
-{

-  /* sync symbol - character that is "on time" - where the time stamp should be taken */
-};
-
-  The flags:
-  F_START         use startsym to find the beginning of the clock data
-  F_END           use endsym to find the end of the clock data
-  SYNC_TIMEOUT    packet restart after timeout in timeout field
-  SYNC_START      packet start is sync event (time stamp at paket start)
-  SYNC_END        packet end is sync event (time stamp at paket end)
-  SYNC_CHAR       special character (syncsym) is sync event
-  SYNC_ONE        PPS synchronize on 'ONE' transition
-  SYNC_ZERO       PPS synchronize on 'ZERO' transition

-  CVT_FIXEDONLY   convert only in fixed configuration - (data format not

-Well, this is very sketchy, i know. But I hope it helps a little bit.
-The best way is to look which clock comes closest to your and tweak that
-code.
-Two sorts of clocks are used with parse. Clocks that automatically send
-their time code (once a second) do not need entries in the poll routines because
-they send the data all the time. The second sort are the clocks that need a
-command sent to them in order to reply with a time code (like the Trimble
-clock).
-
-For questions: kardel@informatik.uni-erlangen.de. Please include
-an exact description on how your clock works. (initialisation,
-TTY modes, strings to be sent to it, responses received from the clock).

-MINI INFO:
-The following info pertains mainly to SunOS4.x in respect to installation.
-Installation for SunOS5.x (Solaris 2.x) is very simple - just drop the parse
-module into /kernel/strmod.
-All others notes about the software structure refer to both environments.
-
-#ifdef ENGLISH
-Installation of a Streams module requires knowledge in kernel generation
-and possession of "superuser" rights.
-
-This directory contains the STREAMS module code for the supported DCF/GPS
-receivers of the "parse" driver.
-The dataformat should be easy to adept for other clocks.
-
-A suitable kernel module can be generated in two ways:
-	1) loadable driver
-	2) linking into the kernel
-
-Solution 1 has the advantage that the kernel module is present right at system startup,
-while solution 2 avoids reconfigurating the kernel (except for VDDRV).
-
-Loadable Driver: (Kernel must be configured with VDDRV option like e.g. GENERIC)
-	make -f Makefile.kernel
-
-#	make one module for each kernel architecture you intend to use this module for
-
-	make -f Makefile.kernel mparsestreams.o
-# use the above command for a version with increased time stamp precision
-# (available only for sun4c and sun4m architectures (thanks Craig Leres)
-
-Integration into kernel (refer to the Manual for complete instructions)
-	Still possible, but not recommended
-
-if you run into trouble: time@informatik.uni-erlangen.de
-
-Porting to different clock formats:
-The streams module is designed to be able to parse different time code
-packets. The parser is very simple and expects at least a start or end of packet
-character. In order to be able to distinguish time code packets a list
-of several start/end pairs and conversion routines can be defined in the
-clockformats structure. Whenever a packet delimited by any start/end pair is 
-detected the conversion routines are called in a RR fashion for converting the 
-time code into a clocktime structure. A return code of CVT_OK indicates a 
-correct conversion.
-(This routine will be called first on the next conversion attempt). CVT_FAIL
-indicates the the packet format was detected, but the actual conversion failed 
-(e.g.  illegal time codes). A CVT_NONE indicates that this conversion routine
-did not recognize the packet format.
-See the simpleformat conversion routines for Meinberg clocks for examples.
-It might be possible to parse other periodically sent time codes with a fixed
-format with these simple conversion routines.
-The parser can be found in parse/*.c
-
-The actual STREAMS module is parsestreams.c. It contains some fudge factors.
-These are needed if a PPS hardware signal is sampled via the serial CD input.
-There are some emperically determined valued for sun4c type machine in there.
-Measurements have shown, that for full precision these values have to be
-determined in the actual environment, as line lengths and capacities DO matter.
-So for absolute precision you need a good oscilloscope and the license for
-hardware work.
-WARNING: DO NOT ATTEMPT TO MEASURE IF YOU ARE NOT ABSOLUTELY CERTAIN WHAT YOU 
-ARE DOING.

-Die folgenden Hinweise zur Uebersetzung und Installation besiehen sich auf
-SunOS 4.x (Solaris1.x). Die Installation auf SunOS5.x (Solaris 2.x) gestaltet
-sich erheblich einfacher. Man muss nur die Daten "parse" in dem Verzeichnis
-/kernel/strmod ablegen.
-Alle anderen Hinweise zur Softwarestruktur sind fuer beide Umgebungen gueltig.
-
-Installation eines STREAMS Moduls setzt Kenntnisse in der Kerngenerierung
-und "Superuser"-Rechte vorraus.
-
-Dieses Inhaltsverzeichnis enthaelt das aktuelle Streams Modul fuer Sun.
-
-Man kann dieses Modul auf zwei Weisen in den Kern integrieren:
-	1) direkt durch Einbinden (neuer Kern)
-	2) als ladbarer Treiber
-
-Loesung 1 hat den Vorteil, dass das Modul gleich nach Systemstart zur 
-Verfuegung steht.
-Loesung 2 besticht dadurch, das man das Modul nachtraeglich laden und 
-auch debuggen kann, ohne einen neuen Kern zu booten.
-
-Fuer ein ladbares Modul muss der Kern mit der VDDRV option konfiguriert sein und das
-parsestreams.c muss mit -DVDDRV uebersetzt werden.
-
-Uebersetzung fuer ladbaren Treiber (Kern muss mit VDDRV konfiguriert sein):
-	make -f Makefile.kernel
-	bitte einmal fuer jede Kernelarchitektur, fuer die dieses Modul
-	benoetigt wird durchfuehren.
-
-	make -f Makefile.kernel mparsestreams.o
-	Das obige make erstellt eine Version, die die Rechneruhr besser
-	als SunOS abliest. Nur fur sun4c und sun4m Architekturen verfuegbar
-
-Uebersetzung als .o Modul oder vorherige Einbindung in die Kernbauumgebung:
-	Immer noch moeglich, wird aber nicht mehr empfohlen.
-
-Anpassung an andere Datenformate:
-Das Streamsmodul ist in der Lage verschiedene Datenformate zu erkennen und
-umzusetzen. Der Parser ist einfach gehalten und kann Datenpakete anhand von
-Start und Endekennzeichen unterscheiden. Jedes so erkannte Paket wird einer 
-Liste von Konvertierroutinen vorgelegt (clockformats Struktur). Die 
-Konvertierroutinen koennen mit drei verschiedenen Rueckgabewerten angeben,
-wie die Konvertierung verlaufen ist. CVT_OK heisst, dass die Konvertierung 
-in die clocktime Struktur erfolgreich verlaufen ist. Beim naechsten 
-Umsetzungsversuch wird diese Routine als erstes wieder befragt werden 
-(Optimierung). CVT_FAIL bedeutet, dass zwar das Format erkannt wurde, aber 
-die eigentliche Konvertierung fehlgeschlagen ist (z. B.  illegale Feldwerte). 
-CVT_NONE heisst, dass das Format dieser Konvertierroutine nicht erkannt wurde.
-Die simpleformat Routinen fuer Meinberg Uhren koennen als Vorlage fuer eigene
-Anpassungen an Uhren mit periodischem Zeittelegramm und festem Format genommen werden.
-Der Parser ist in parse/*.c zu finden.
-
-Das eigentliche STREAMSmodul ist parsestreams.c. Es enthaelt einige 
-Korrekturfaktoren, die beim Einsatz von Hardware-PPS Signalen benoetigt werden.
-Einige empirische Werte fuer sun4c Maschinen sind schon vorgegeben. Bei exterm 
-hohen Genauigkeitsanforderungen muessen diese Werte aber in der aktuellen 
-Installation NEU ermittelt werden, weil die Zeiten unter anderem von 
-Leitunglaengen der PPS Leitung abhaengen.  Wenn Sie diese Abstimmung 
-durchfuehren, benoetigen Sie ein gutes Oszilloskop und die Lizenz fuer 
-Hardwarearbeiten.
-
-ACHTUNG: VERSUCHEN SIE NICHT DIESE MESSUNGEN ZU MACHEN, WENN IHNEN DIE
-VORAUSSETZUNGEN DAFUER FEHLEN !

-	Meinberg is a german manufacturer of time code receivers. Those clocks
-	have a pretty common output format in the stock version. In order to
-	support NTP Meinberg was so kind to produce some special versions of
-	the firmware for the use with NTP. So, if you are going to use a
-	Meinberg clock please ask whether there is a special Uni Erlangen
-	version.
-
-	General characteristics:
-	Meinberg clocks primarily output pulse per second and a describing
-	ASCII string. This string can be produced in two modes. either upon
-	the reception of a question mark or every second. NTP uses the latter
-	mechanism. The DCF77 variants have a pretty good relationship between
-	RS232 time code and the PPS signal while the GPS receiver has no fixed
-	timeing between the datagram and the pulse (you need to use PPS with
-	GPS!) on DCF77 you might get away without the PPS signal.
-
-	The preferred tty setting for Meinberg is:
-		CFLAG		(B9600|CS7|PARENB|CREAD|HUPCL)
-		IFLAG		(IGNBRK|IGNPAR|ISTRIP)
-		OFLAG		0
-		LFLAG		0
-
-	The clock is run at datagram once per second.
-	Stock dataformat is:

-    For the university of Erlangen a special format was implemented to support

-
-    Version for UNI-ERLANGEN Software is: PZFUERL V4.6 (Meinberg)
-
-    The use of this software release (or higher) is *ABSOLUTELY*
-    recommended (ask for PZFUERL version as some minor HW fixes have
-    been introduced) due to the LEAP second support and UTC indication.
-    The standard timecode does not indicate when the timecode is in

-    the correct utc offset. For the standard format do not ever use
-    UTC display as this is not detectable in the time code !!!

-
-	The command to Schmid's DCF77 clock is a single byte; each bit
-	allows the user to select some part of the time string, as follows (the
-	output for the lsb is sent first).
-	
-	Bit 0:	time in MEZ, 4 bytes *binary, not BCD*; hh.mm.ss.tenths

- * Trimble TSIP parser
- *
- * The receiver uses a serial message protocol called Trimble Standard
- * Interface Protocol (it can support others but this driver only supports
- * TSIP). Messages in this protocol have the following form:
- *
- * <DLE><id> ... <data> ... <DLE><ETX>
- *
- * Any bytes within the <data> portion of value 10 hex (<DLE>) are doubled
- * on transmission and compressed back to one on reception. Otherwise
- * the values of data bytes can be anything. The serial interface is RS-422
- * asynchronous using 9600 baud, 8 data bits with odd party (**note** 9 bits
- * in total!), and 1 stop bit. The protocol supports byte, integer, single,
- * and double datatypes. Integers are two bytes, sent most significant first.
- * Singles are IEEE754 single precision floating point numbers (4 byte) sent
- * sign & exponent first. Doubles are IEEE754 double precision floating point
- * numbers (8 byte) sent sign & exponent first.
- * The receiver supports a large set of messages, only a small subset of
- * which are used here. From driver to receiver the following are used:
- *
- *  ID    Description
- *
- *  21    Request current time
- *  22    Mode Select
- *  2C    Set/Request operating parameters
- *  2F    Request UTC info
- *  35    Set/Request I/O options
- *
- * From receiver to driver the following are recognised:
- *
- *  ID    Description
- *
- *  41    GPS Time
- *  44    Satellite selection, PDOP, mode
- *  46    Receiver health
- *  4B    Machine code/status
- *  4C    Report operating parameters (debug only)
- *  4F    UTC correction data (used to get leap second warnings)
- *  55    I/O options (debug only)
- *
- * All others are accepted but ignored.

-README file for directory ./scripts of the NTP Version 3 distribution
-
-This directory contains shell and perl script files for the configuration,
-monitoring and support of NTP installations. See the README and RELNOTES
-files in the parent directory for directions on how to use these files.
-
-Guess.sh        script to figure out what machine and operating system
-                is running this thing. Prizes awarded for new machines
-                added to the list.
-
-autoconf        awesome script swiped from Jeff Johnson (who may have
-                swiped it from GNU) which delves deep into the system
-                files to reveal dark secrets necessary to port NTP to
-                everything except sewing machines. Unfinished work.
-
-makeconfig.sh   shell script that calles Guess.sh and then figures out
-                what compiler is available, then builds the

-This directory contains support for monitoring the local clock of xntp daemons.
-
-WARNING: The scripts and routines contained in this directory are bete realease!
-	 Do not depend on their correct operation. They are, however, in regular
-	 use at University of Erlangen-Nuernberg. No severe problems are known
-	 for this code.
-
-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-PLEASE THINK TWICE BEFORE STARTING MONITORING REMOTE XNTP DEAMONS !!!!
-MONITORING MAY INCREASE THE LOAD OF THE DEAMON MONITORED AND MAY
-INCREASE THE NETWORK LOAD SIGNIFICANTLY 
-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-
-Files are:
-
-README:
-	This file
-
-ntptrap:
-	perl script to log ntp mode 6 trap messages.
-
-	It sends a set_trap request to each server given and dumps the
-	trap messages received. It handles refresh of set_trap.
-	Currently it handles only NTP V2, however the NTP V3 servers
-	also accept v2 requests. It will not interpret v3 system and peer
-	stati correctly.
-
-	usage:
-	  ntptrap [-n] [-p <port>] [-l <debug-output>] servers...
-	
-	-n:		do not send set_trap requests
-
-	port:		port to listen for responses
-			useful if you have a configured trap
-
-	debug-output:	file to write trace output to (for debugging)
-
-	This script convinced me that ntp trap messages are only of
-	little use.
-
-ntploopstat:
-	perl script to gather loop info statistics from xntpd via mode 7
-	LOOP_INFO requests.
-
-	This script collects data to allow monitoring of remote xntp servers
-	where it is not possible to directly access the loopstats file
-	produced by xntpd itself. Of course, it can be used to sample
-	a local server if it is not configured to produce a loopstats file.
-
-	Please note, this program poses a high load on the server as
-	a communication takes place every delay seconds ! USE WITH CARE !
-
-	usage:
-	  ntploopstat [-d<delay>] [-t<timeout>] [-l <logfile>] [-v] [ntpserver]
-	
-	delay:		number of seconds to wait between samples
-			default: 60 seconds
-	timeout:	number of seconds to wait for reply
-			default 12 seconds
-	logfile:	file to log samples to
-			default: loopstats:<ntpserver>:
-			(note the trailing colon)
-			This name actually is a prefix.
-			The file name is dynamically derived by appending
-			the name of the month the sample belongs to.
-			Thus all samples of a month end up in the same file.
-
-	the format of the files generated is identical to the format used by
-	xntpd with the loopstats file:
-		MJD <seconds since midnight UTC> offset frequency compliance
-	
-	if a timeout occurs the next sample is tried after delay/2 seconds
-
-	The script will terminate after MAX_FAIL (currently 60) consecutive errors.
-	Errors are counted for:
-		- error on send call
-		- error on select call
-		- error on recv call
-		- short packet received
-		- bad packet 
-		- error on open for logfile
-
-ntploopwatch:
-	perl script to display loop filter statistics collected by ntploopstat
-	or dumped directly by xntpd.
-
-	Gnuplot is used to produce a graphical representation of the sample
-	values, that have been preprocessed and analysed by this script.
-
-	It can either be called to produce a printout of specific data set or
-	used to continously monitor the values. Monitoring is achieved by 
-	periodically reprocessing the logfiles, which are updated regularly
-	either by a running ntploopstat process or by the running xntpd.
-
-	usage:
-	  to watch statistics permanently:
-	     ntploopwatch [-v[<level>]] [-c <config-file>] [-d <working-dir>]
-
-	  to get a single print out specify also
-			  -P<printer> [-s<samples>]
-				      [-S <start-time>] [-E <end-time>]
-				      [-O <MaxOffs>] [-o <MinOffs>]
-	
-	level:		level of verbosity for debugging
-	config-file:	file to read configurable settings from
-			On each iteration it is checked and reread
-			if it has been changed
-			default: loopwatch.config
-	working-dir:	specify working directory for process, affects
-			interpretation of relative file names
-	
-	All other flags are only useful with printing plots, as otherwise
-	command line values would be replaced by settings from the config file.
-
-	printer:	specify printer to print plot
-			BSD print systems semantics apply; if printer is omitted
-			the name "ps" is used; plots are prepared using
-			PostScript, thus the printer should best accept
-			postscript input
-
-	For the following see also the comments in loopwatch.config.SAMPLE
-
-	samples:	use last # samples from input data
-	start-time:	ignore input samples before this date
-	end-time:	ignore input samples after this date
-			if both start-time and end-time are specified
-			a given samples value is ignored
-	MaxOffs:
-	MinOffs:	restrict value range 
-
-loopwatch.config.SAMPLE:
-	sample config file for ntploopwatch
-	each configurable option is explained there
-
-lr.pl:
-	linear regression package used by ntploopwatch to compute
-	linear approximations for frequency and offset values
-	within display range
-
-timelocal.pl:
-	used during conversion of ISO_DATE_TIME values specified in loopwatch
-	config files to unix epoch values (seconds since 1970-01-01_00:00_00 UTC)
-
-	A version of this file is distributed with perl-4.x, however,
-	it has a bug related to dates crossing 1970, causing endless loops..
-	The version contained here has been fixed.
-
-ntp.pl:
-	perl support for ntp v2 mode 6 message handling
-	WARNING: This code is beta level - it triggers a memory leak;
-		 as for now it is not quite clear, wether this is caused by a
-		 bug in perl or by bad usage of perl within this script.

-;# Usage:

-;#	$time = timegm($sec,$min,$hours,$mday,$mon,$year);
-
-;# These routines are quite efficient and yet are always guaranteed to agree
-;# with localtime() and gmtime().  We manage this by caching the start times
-;# of any months we've seen before.  If we know the start time of the month,
-;# we can always calculate any time within the month.  The start times
-;# themselves are guessed by successive approximation starting at the
-;# current time, since most dates seen in practice are close to the
-;# current date.  Unlike algorithms that do a binary search (calling gmtime
-;# once for each bit of the time value, resulting in 32 calls), this algorithm
-;# calls it at most 6 times, and usually only once or twice.  If you hit
-;# the month cache, of course, it doesn't call it at all.
-
-;# timelocal is implemented using the same cache.  We just assume that we're
-;# translating a GMT time, and then fudge it when we're done for the timezone
-;# and daylight savings arguments.  The timezone is determined by examining
-;# the result of localtime(0) when the package is initialized.  The daylight

-Statistics processing scripts (README)
-
-This directory contains a number of scripts for use with the filegen
-facility. Those files ending in .awk are for the Unix awk utility, while
-those ending in .sh are for the csh utility. Normally, the summary.sh
-script is called from a cron job once per day. This script processes the
-daily loopstats, peerstats and clockstats files produced by the daemon,
-updates the loop_summary, peer_summary and clock_summary archive files,
-and deletes the daily files.
-
-In the case of the Austron 2201A GPS receiver, the clockstats file
-contains a wealth of additional monitoring data. These data are summarized
-and writted to the clock_summary file, then a series of special files are
-constructed for later processing by the S utility.
-
-The summary.sh script invokes a number of awk scripts to actually produce
-the data. This may result in multiple scans of the same input file.
-The input file is deleted after processing. In fact, the shell scripts will
-process all input files found of the correct type in chronological order,
-deleting each one as it is scanned, except the current day file.
-
-The summary.sh script can produce input files for the S utility, if it
-is found on the search path. This utility makes PostScript graphs of the
-loopstats data for each day, as well as various statistics produced by
-the Austorn 220aA GPS receiver. The S utility is automatically run
-as a background job. Its control files have the .S extension.
-
-The psummary.awk script can be used to scan the peer_summary file and
-construct an historical reprise of the daily summaries. 
-
-The file formats are documented in the README.stats file and in the
-scripts themselves. Further detail on the radio clock ASCII timecode
-formats and related data are in the README.timecode file.

-Statistics file formats (README.stats)
-
-The xntp3 daemon can produce a variety of statistics files which are
-useful for maintenance, evaluation and retrospective calibration
-purposes. See the xntpd.8 man page for instructions on how to configure
-this feature. Since these files can become rather large and cumbersome,
-they are ordinarily reduced to summary form by running the summary.sh
-shell script once per day, week or month, as appropriate. There are
-three file collections presently defined: peerstats, loopstats and
-clockstats, each of which is described in this note.
-
-peerstats
-
-The following data are collected in the peerstats files. The files are
-reduced to summary data using the peer.sh shell script. See the peer.awk
-script for further information. A line in the file is produced upon
-reception of each valid update from a configured peer.
-
-  49236 30.756 140.173.96.1 9474 0.000603 0.37532
-
-  49236             modified Julian day number
-  30.756            time of day (s) past midnight UTC
-  140.173.96.1      peer identifier (IP address or receiver identifier)
-  9474              peer status word (hex) (see NTP specification)
-  0.000603          offset (s)
-  0.08929           delay (s)
-  0.37532           dispersion (s)
-
-loopstats
-
-The following data are collected in the loopstats files. The files are
-reduced to summary data using the loop.sh shell script. See the loop.awk
-script for further information. A line in the file is produced at each
-valid update of the local clock.
-
-  49236 11.897 -0.000004 -35.9384 0
-
-  49236             modified Julian day number

-  -35.9384          frequency offset (ppm)
-  0                 phase-lock loop time constant
-
-clockstats
-
-The following data are collected in the clockstats files. The files are
-reduced to summary data using the clock.sh shell script, which also
-updates the ensemble, etf, itf and tdata data files as well. See the
-clock.awk, ensemble.awk, etf.awk, itf.awk and tdta.awk scripts for
-further information. A line in the file is produced at each valid update
-received from a configured radio clock. Data are at present recorded for
-several radios. The first part of each data line is similar for all
-radios, e.g.:
-
-  49234 60517.826 127.127.4.1   93 247 16:48:21.814
-
-  49234             modified Julian day number
-  60517.826         time of day (s) past midnight UTC
-  127.127.4.1       receiver identifier (Spectracom 8170/Netclock-2)
-  93 247 16:48:21.814  timecode (format varies)
-
-In the case of the Austron GPS receiver, a good deal of additional
-information is extracted from the radio, as described below. The formats
-shown consist of one line with all the fields shown in order. The
-timecode formats specific to each radio follow. See the file
-README.timecodes for detailed information on the timecode formats used
-by these radios.

-
-Depending on the installed options, the Austron 2200A/2201A recognizes a
-number of special commands that report various data items. See the
-refclock_as2201.c source module for a list of the commands used. These

-Radio Timecode Formats (README.timecodes)
-
-Following are examples of the serial timecode formats used by various
-timecode receivers as given in the instruction manuals. These examples
-are intended only for illustration and not as the basis of system
-design. The following symbols are used to identify the timecode
-character that begins a subfield. The values given after this symbol
-represent the character offset from the beginning of the timecode string
-as edited to remove control characters.
-
-C         on-time character (start bit)
-Y         year of century
-T         time of day
-D         day of year or month/day
-A         alarm indicator (format specific)
-Q         quality indicator (format specific)
-<LF>      ASCII line feed (hex 0a)
-<CR>      ASCII carriage return (hex 0d)
-<SP>      ASCII space (hex 20)
-
-In order to promote uniform behavior in the various implementations, it
-is useful to have a common interpretation of alarm conditions and signal
-quality. When the alarm indicator it on, the receiver is not operating
-correctly or has never synchronized to the broadcast signal. When the
-alarm indicator is off and the quality indicator is on, the receiver has
-synchronized to the broadcast signal, then lost the signal and is
-coasting on its internal oscillator.
-
-In the following uppercase letters, punctuation marks and spaces <SP>
-stand for themselves; lowercase letters stand for fields as described.
-Special characters other than <LF>, <CR> and <SP> are preceded by ^.

-The bin and etc directories contain several scripts (sh and perl) that
-should ease startup and configuration of NTP sites.
-
-	bin/monl is a monitoring script that prints out new, current and
-	         old customers of an NTP timeserver when monitoring is
-		 in effect.
-		 monl has following options:
-		 -i <regexp> (regular expression matchin IP addres to be ignored
-		 -d <directory> where the current state is kept (default /tmp)
-		 -v debug output
-		 -n do not translate IP addresses into hostnames
-		 <host> host to be analyzed
-
-		 monl uses xntpdc for information gathering and is thus
-		 limited to the NTP version xntpdc is compiled for.
-
-	bin/mvstats moves compresses and removes statistics files (useful mainly
-		    for reference servers
-
-	etc/install creates the locally needed directories for NTP (if not residung in /etc)
-
-	etc/rc   starts up daemon with configuration file and key file
-	etc/cron cron called monitor statistic (uses bin/monl)
-	etc/crontab crontab prototype for reference time servers
-	etc/setup   sh script sourced by the other scripts for variable setup
-
-YOU MUST EDIT THESE FILES TO REFLECT YOUR LOCAL SETUP !
-
-READ THIS BEFORE USING THE STARTUP SCRIPTS
-
-The startupscript etc/rc has been written for Suns and HPs. They are not 
-guaranteed to work elsewhere. Following assumptions have been made:
-
-	All NTP related files reside in ONE directory having following structure:
-
-		bin/*	-	all executables (daemon, control, date, scripts)
-		etc/*	-	startup scripts and cron scripts
-		conf/*	-	NTP configuration files
-
-The variable NTPROOT (etc/rc, etc/install) must be edited to reflect 
-the NTP directory (e.g. /usr/local/NTP)
-
-NTP config files are located via Suns arch command and have the name
-conf/`arch`.`arch -k`.
-These are the default configurations (usually clients). If a file with the name
-conf/`arch`.`arch -k`.`hostname` is present this file will be preferred (Reference host,
-gateway). If the arch command is not available no-arch is used. The arch command
-is usually a shell script which echoes a string unique the the current machine
-architecture.
-
-The tickadj command has its own conf/tickconf file which is used to set host
-specific tickadj values. The line with DEFAULT specifies the default tickadj
-parameters, all other lines consists of <hostname> <hostid>
-<tickadj parameters>. These lines need only be entered if the specified host
-needs parameters different from the default parameters.
-
-Reference clock support is provided for DCF77. If you need to initialize
-certain things for reference clock support (e.g. loading STREAMS modules),
-you need to edit etc/rc.
-
-The current config files of Erlangen are included in the conf directory.
-They are just for reference, but might help you a bit in setting up a
-synchronisation network.
-
-The advantage of keeping all config files centralized is the easier 
-administration.
-
-We replicate the NTP directory via NFS and rdist.
-
-When you have set up the local config files (YOUR OWN!) you can call 
-<NTPROOT>/etc/rc for daemon startup.

-README file for directory ./util of the NTP Version 3 distribution
-
-This directory contains the sources for the various utility programs. See
-the README and RELNOTES files in the parent directory for directions on
-how to make and install these programs.
-
-The ntptime.c program checks the kernel configuration for the NTP user
-interface syscalls ntp_gettime() and ntp_adjtime(). If present, the
-current timekeeping data are displayed. If not, a dissapointment is
-displayed. Do "make ntptime" in this directory to make the thing,
-but be advised that, unless you have installed the kernel support,
-there will probably be missing vital header files. See the README.kern
-file in the doc directory of this distribution for further details.
-
-The jitter.c program can be used to determine the timing jitter due to
-the operating system in a gettimeofday() call. For most systems the
-dominant contribution to the jitter budget is the period of the hardware
-interrupt, usually in the range 1-10 ms. For those systems with microsecond
-counters, such as recent Sun and certain Ultrix systems, the jitter is
-dominated only by the operating system. 
-
-The timetrim.c program can be used with SGI machines to implement a
-scheme to discipline the hardware clock frequency. See the source code
-for further information.
-
-The byteorder.c and longsize.c programs are used during the configuration
-process to determine the byte order (little or big endian) and longword
-size (32 or 64 bits). See the ../scripts/makefile.sh script for further
-details.
-
-The testrs6000.c program is used for testing purposes with the IBM
-RS/6000 AIX machines. Bill Jones <jones@chpc.utexas.edu> reports:
-"I could not get a tickadj of less then 40 us to work on a RS6000.
-If you set it less then 40 us do so at your own risk!"
-
-The tickadj.c program can be used to read and set various kernel
-parameters affecting NTP operations. Comes now the rationale for its use.
-
-Then daemon's clock adjustment algorithms depend (too) strongly
-on the internals of the kernel adjtime() call, and expect it to
-match that which comes with Berkeley-flavour operating systems.
-The daemon actually reads a couple of values from your kernel
-using /dev/kmem (ugh!), the value of `tick' and the value of `tickadj'.
-`tick' is expected to be the number of microseconds which are
-added to the system time on timer interrupts when the clock isn't
-being slewed.  `tickadj' is the number of microseconds which are
-added or subtracted from tick when the clock is being slewed.
-
-The program tickadj mimics the daemon's handling of these variables.
-If you run it (as root) and it fails or produces bizarre looking
-values you may have to torque ntp_unixclock.c in the daemon code.
-
-You can also use tickadj -a to set tickadj in the running kernel.
-In addition, tickadj -A will compute the value to set based on the
-kernel's value of tick, while the -t flag allows one to set the
-value of tick and the -s flag will set the value of dosynctodr
-to zero.  This is an alternative for people who can't change the
-values in the kernel's disk image.
-
-In addition, the -p flag will set the noprintf variable. This will
-suppress any kernel messages. Kernel message can then only be seen via
-syslog(3). This inhibits clockhopping due to kernel printf's.
-
-The target "ntptime" can only be compiled on systems with kernel PLL
-support. This is currently only possible for SunOS4, Ultrix and DECOSF1.
-You need the propriatary header files for that. So there is no need to
-attempt to compile ntptime unless you have the above configuration.

- * the system clock step ahead 1 nanosecond more per second than a value

- * offset (drift) values; to convert to a timetrim value, multiply by

- *
- * "timetrim" with no arguments just prints out the current kernel value.
- * With a numeric argument, the kernel value is set to the supplied value.
- * The "-i" flag causes the supplied value to be added to the kernel value.
- * The "-n" option causes all input and output to be in xntpd units rather
- * than timetrim native units.
- *
- * Note that there is a limit of +-3000000 (0.3%) on the timetrim value

-/*
- * This module is devoted to maintaining the leap bits and taking
- * action when a leap second occurs.  It probably has bugs since
- * a leap second has never occurred to excercise the code.
- *
- * The code does two things when a leap second occurs.  It first
- * steps the clock one second in the appropriate direction.  It
- * then informs the reference clock code, if compiled in, that the
- * leap second has occured so that any clocks which need to disable
- * themselves can do so.  This is done within the first few seconds
- * after midnight, UTC.
- *
- * The code maintains two variables which may be written externally,
- * leap_warning and leap_indicator.  Leap_warning can be written
- * any time in the month preceeding a leap second.  24 hours before
- * the leap is to occur, leap_warning's contents are copied to
- * leap_indicator.  The latter is used by reference clocks to set
- * their leap bits.
- *
- * The module normally maintains a timer which is arranged to expire
- * just after 0000Z one day before the leap.  On the day a leap might
- * occur the interrupt is aimed at 2200Z and every 5 minutes thereafter
- * until 1200Z to see if the leap bits appear.

- * The loop filter is implemented in slavish adherence to the
- * specification (Section 5), except that for consistency we
- * mostly carry the quantities in the same units as appendix G.
- *
- * Note that the long values below are the fractional portion of
- * a long fixed-point value.  This limits these values to +-0.5
- * seconds.  When adjustments are capped inside this range (see
- * CLOCK_MAX_{I,F}) both the clock_adjust and the compliance
- * registers should be fine. (When the compliance is above 16, it
- * will at most accumulate 2 ** CLOCK_MULT times the maximum offset,
- * which means it fits in a s_fp.)
- *
- * The skew compensation is a special case. In version 2, it was
- * kept in ms / 4s (i.e., CLOCK_FREQ was 10). In version 3 (Section 5)
- * it seems to be 2 ** -16ms / 4s in a s_fp for a maximum of +-125ppm
- * (stated maximum 100ppm). Since this seems about to change to a
- * larger range, it will be kept in units of 2 ** -20 (CLOCK_DSCALE)
- * in an s_fp (mainly because that's nearly the same as parts per
- * million). Note that this is ``seconds per second'', whereas a
- * clock adjustment is a 32-bit fraction of a second to be applied
- * every 2 ** CLOCK_ADJ seconds; to find it, shift the drift right by
- * (CLOCK_DSCALE - 16 - CLOCK_ADJ). When updating the drift, on the
- * other hand, the CLOCK_FREQ factor from the spec assumes the value to
- * be in ``seconds per 4 seconds''; to get our units, CLOCK_ADJ must be
- * added to the shift.
- *
- * Kernel PLL/PPS state machine
- *
- * The following state machine is used when the kernel PLL modifications
- * described in the README.kernel file are present. The initial
- * configuration routine loop_config() sets up the initial frequency
- * estimate and tests if the kernel modifications are present. If so and
- * the PLL mode bit 1 (STA_PLL) of the mode word in the drift file
- * (ntp.drift) is set, pll_control is set true and the kernel pll is
- * enabled. If the kernel modifications are present and the PLL mode bit
- * 2 (STA_PPSFREQ) is set, the kernel PPS frequency discipline is
- * enabled.
- *
- * Each update to a prefer peer sets pps_update true if it survives the
- * intersection algorithm and its time is within range. The PPS time
- * discipline is enabled (STA_PPSTIME bit set in the status word) when
- * pps_update is true and the PPS frequency discipline is enabled. If
- * the PPS time discipline is enabled and the kernel reports a PPS
- * signal is present, the pps_control variable is set to the current
- * time. If the current time is later than pps_control by PPS_MAXAGE
- * (120 s), this variable is set to zero.
- *
- * The pll_enable switch can be set both at configuration time and at
- * run time using xntpdc. If true, the kernel modifications are active
- * as described above; if false, the kernel is bypassed entirely (except
- * for the PPS frequency update, if enabled) and the daemon PLL used
- * instead.

- * Reference clock support is provided here by maintaining the fiction
- * that the clock is actually a peer. As no packets are exchanged with a
- * reference clock, however, we replace the transmit, receive and packet
- * procedures with separate code to simulate them. Routines
- * refclock_transmit() and refclock_receive() maintain the peer
- * variables in a state analogous to an actual peer and pass reference
- * clock data on through the filters. Routines refclock_peer() and
- * refclock_unpeer() are called to initialize and terminate reference
- * clock associations. A set of utility routines is included to open
- * serial devices, process sample data, edit input lines to extract
- * embedded timestamps and to peform various debugging functions.
- *
- * The main interface used by these routines is the refclockproc
- * structure, which contains for most drivers the decimal equivalants of
- * the year, day, month, hour, second and millisecond/microsecond
- * decoded from the ASCII timecode. Additional information includes the
- * receive timestamp, exception report, statistics tallies, etc. In
- * addition, there may be a driver-specific unit structure used for
- * local control of the device.
- *
- * The support routines are passed a pointer to the peer structure,
- * which is used for all peer-specific processing and contains a pointer
- * to the refclockproc structure, which in turn containes a pointer to
- * the unit structure, if used. In addition, some routines expect an
- * address in the dotted quad form 127.127.t.u, where t is the clock
- * type and u the unit. A table typeunit[type][unit] contains the peer
- * structure pointer for each configured clock type and unit.
- *
- * Most drivers support the 1-pps signal provided by some radios and
- * connected via a level converted described in the gadget directory.
- * The signal is captured using a separate, dedicated serial port and
- * the tty_clk line discipline/streams modules described in the kernel
- * directory. For the highest precision, the signal is captured using
- * the carrier-detect line of the same serial port using the ppsclock
- * streams module described in the ppsclock directory.

- * This code keeps a simple address-and-mask list of hosts we want
- * to place restrictions on (or remove them from).  The restrictions
- * are implemented as a set of flags which tell you what the host
- * can't do.  There is a subroutine entry to return the flags.  The
- * list is kept sorted to reduce the average number of comparisons
- * and make sure you get the set of restrictions most specific to
- * the address.
- *
- * The algorithm is that, when looking up a host, it is first assumed
- * that the default set of restrictions will apply.  It then searches
- * down through the list.  Whenever it finds a match it adopts the match's
- * flags instead.  When you hit the point where the sorted address is
- * greater than the target, you return with the last set of flags you
- * found.  Because of the ordering of the list, the most specific match
- * will provide the final set of flags.
- *
- * This was originally intended to restrict you from sync'ing to your
- * own broadcasts when you are doing that, by restricting yourself
- * from your own interfaces.  It was also thought it would sometimes
- * be useful to keep a misbehaving host or two from abusing your primary
- * clock.  It has been expanded, however, to suit the needs of those
- * with more restrictive access policies.

-/*
- * This driver supports the NIST Automated Computer Time Service (ACTS).
- * It periodically dials a prespecified telephone number, receives the
- * NIST timecode data and calculates the local clock correction. It is
- * designed primarily for use as a backup when neither a radio clock nor
- * connectivity to Internet time servers is available. For the best
- * accuracy, the individual telephone line/modem delay needs to be
- * calibrated using outside sources.
- *
- * The ACTS is located at NIST Boulder, CO, telephone 303 494 4774. A
- * toll call from a residence telephone in Newark, DE, costs between 14
- * and 27 cents, depending on time of day, and from a campus telephone
- * between 3 and 4 cents, although it is not clear what carrier and time
- * of day discounts apply in this case. The modem dial string will
- * differ depending on local telephone configuration, etc., and is
- * specified by the phone command in the configuration file. The
- * argument to this command is an AT command for a Hayes compatible
- * modem.
- *
- * The accuracy produced by this driver should be in the range of a
- * millisecond or two, but may need correction due to the delay
- * characteristics of the individual modem involved. For undetermined
- * reasons, some modems work with the ACTS echo-delay measurement scheme
- * and some don't. This driver tries to do the best it can with what it
- * gets. Initial experiments with a Practical Peripherals 9600SA modem
- * here in Delaware suggest an accuracy of a millisecond or two can be
- * achieved without the scheme by using a fudge time1 value of 65.0 ms.
- * In either case, the dispersion for a single call involving ten
- * samples is about 1.3 ms.
- *
- * The driver can operate in either of three modes, as determined by
- * the mode parameter in the server configuration command. In mode 0
- * (automatic) the driver operates continuously at intervals depending
- * on the prediction error, as measured by the driver, usually in the
- * order of several hours. In mode 1 (backup) the driver is enabled in
- * automatic mode only when no other source of synchronization is
- * available and when more than MAXOUTAGE (3600 s) have elapsed since
- * last synchronized by other sources. In mode 2 (manual) the driver
- * operates only when enabled using a fudge flags switch, as described
- * below.
- *
- * For reliable call management, this driver requires a 1200-bps modem
- * with a Hayes-compatible command set and control over the modem data
- * terminal ready (DTR) control line. Present restrictions require the
- * use of a POSIX-compatible programming interface, although other
- * interfaces may work as well. The modem setup string is hard-coded in
- * the driver and may require changes for nonstandard modems or special
- * circumstances.
- *
- * Further information can be found in the README.refclock file in the
- * xntp3 distribution.
- *
- * Fudge Factors
- *
- * Ordinarily, the propagation time correction is computed automatically
- * by ACTS and the driver. When this is not possible or erratic due to
- * individual modem characteristics, the fudge flag2 switch should be
- * set to disable the ACTS echo-delay scheme. In any case, the fudge
- * time1 parameter can be used to adjust the propagation delay as
- * required.
- *
- * The ACTS call interval is determined in one of three ways. In manual
- * mode a call is initiated by setting fudge flag1 using xntpdc, either
- * manually or via a cron job. In AUTO mode this flag is set by the peer
- * timer, which is controlled by the sys_poll variable in response to
- * measured errors. In backup mode the driver is ordinarily asleep, but
- * awakes (in auto mode) if all other synchronization sources are lost.
- * In either auto or backup modes, the call interval increases as long
- * as the measured errors do not exceed the value of the fudge time2
- * parameter.
- *
- * When the fudge flag1 is set, the ACTS calling program is activated.
- * This program dials each number listed in the phones command of the
- * configuration file in turn. If a call attempt fails, the next number
- * in the list is dialed. The fudge flag1 and counter are reset and the
- * calling program terminated if (a) a valid clock update has been
- * determined, (b) no more numbers remain in the list, (c) a device
- * fault or timeout occurs or (d) fudge flag1 is reset manually using
- * xntpdc.
- *
- * In automatic and backup modes, the driver determines the call
- * interval using a procedure depending on the measured prediction
- * error and the fudge time2 parameter. If the error exceeds time2 for a
- * number of times depending on the current interval, the interval is
- * decreased, but not less than about 1000 s. If the error is less than
- * time2 for some number of times, the interval is increased, but not
- * more than about 18 h. With the default value of zero for fudge time2,
- * the interval will increase from 1000 s to the 4000-8000-s range, in
- * which the expected accuracy should be in the 1-2-ms range. Setting
- * fudge time2 to a large value, like 0.1 s, may result in errors of
- * that order, but increase the call interval to the maximum. The exact
- * value for each configuration will depend on the modem and operating
- * system involved, so some experimentation may be necessary.

- * etc..etc...etc.......
- *
- * UTC = Universal Time Coordinated, the official world time referred to
- * the zero meridian.
- *
- * DST	Daylight savings time characters, valid for the continental
- *	U.S., are set as follows:
- *
- *	00	We are on standard time (ST).
- *	01-49	Now on DST, go to ST when your local time is 2:00 am and
- *		the count is 01. The count is decremented daily at 00
- *		(UTC).
- *	50	We are on DST.
- *	51-99	Now on ST, go to DST when your local time is 2:00 am and
- *		the count is 51. The count is decremented daily at 00
- *		(UTC).
- *
- *	The two DST characters provide up to 48 days advance notice of a
- *	change in time. The count remains at 00 or 50 at other times.
- *
- * LS	Leap second flag is set to "1" to indicate that a leap second is
- *	to be added as 23:59:60 (UTC) on the last day of the current UTC
- *	month. The LS flag will be reset to "0" starting with 23:59:60
- *	(UTC). The flag will remain on for the entire month before the
- *	second is added. Leap seconds are added as needed at the end of
- *	any month. Usually June and/or December are chosen.
- *
- *	The leap second flag will be set to a "2" to indicate that a
- *	leap second is to be deleted at 23:59:58--00:00:00 on the last
- *	day of the current month. (This latter provision is included per
- *	international recommendation, however it is not likely to be
- *	required in the near future.)
- *
- * DUT1	Approximate difference between earth rotation time (UT1) and
- *	UTC, in steps of 0.1 second: DUT1 = UT1 - UTC.
- *
- * MJD	Modified Julian Date, often used to tag certain scientific data.
- *
- * The full time format is sent at 1200 baud, 8 bit, 1 stop, no parity.
- * The format at 300 Baud is also 8 bit, 1 stop, no parity. At 300 Baud
- * the MJD and DUT1 values are deleted and the time is transmitted only
- * on even seconds.
- *
- * Maximum on line time will be 56 seconds. If all lines are busy at any
- * time, the oldest call will be terminated if it has been on line more
- * than 28 seconds, otherwise, the call that first reaches 28 seconds
- * will be terminated.
- *
- * Current time is valid at the "on-time" marker (OTM), either "*" or
- * "#". The nominal on-time marker (*) will be transmitted 45 ms early
- * to account for the 8 ms required to send 1 character at 1200 Baud,
- * plus an additional 7 ms for delay from NIST to the user, and
- * approximately 30 ms "scrambler" delay inherent in 1200 Baud modems.
- * If the caller echoes all characters, NIST will measure the round trip
- * delay and advance the on-time marker so that the midpoint of the stop
- * bit arrives at the user on time. The amount of msADV will reflect the
- * actual required advance in milliseconds and the OTM will be a "#".
- *
- * (The NIST system requires 4 or 5 consecutive delay measurements which
- * are consistent before switching from "*" to "#". If the user has a
- * 1200 Baud modem with the same internal delay as that used by NIST,
- * then the "#" OTM should arrive at the user within +-2 ms of the
- * correct time.
- *
- * However, NIST has studied different brands of 1200 Baud modems and
- * found internal delays from 24 ms to 40 ms and offsets of the "#" OTM
- * of +-10 ms. For many computer users, +-10 ms accuracy should be more
- * than adequate since many computer internal clocks can only be set
- * with granularity of 20 to 50 ms. In any case, the repeatability of
- * the offset for the "#" OTM should be within +-2 ms, if the dial-up
- * path is reciprocal and the user doesn't change the brand or model of
- * modem used.
- *
- * This should be true even if the dial-up path on one day is a land-
- * line of less than 40 ms (one way) and on the next day is a satellite
- * link of 260 to 300 ms. In the rare event that the path is one way by
- * satellite and the other way by land line with a round trip
- * measurement in the range of 90 to 260 ms, the OTM will remain a "*"
- * indicating 45 ms advance.

- * This driver supports the Austron 2200A/2201A GPS Receiver with
- * Buffered RS-232-C Interface Module. Note that the original 2200/2201
- * receivers will not work reliably with this driver, since the older
- * design cannot accept input commands at any reasonable data rate.
- *
- * The program sends a "*toc\r" to the radio and expects a response of
- * the form "yy:ddd:hh:mm:ss.mmm\r" where yy = year of century, ddd =
- * day of year, hh:mm:ss = second of day and mmm = millisecond of
- * second. Then, it sends statistics commands to the radio and expects
- * a multi-line reply showing the corresponding statistics or other
- * selected data. Statistics commands are sent in order as determined by
- * a vector of commands; these might have to be changed with different
- * radio options. If flag4 of the fudge configuration command is set to
- * 1, the statistics data are written to the clockstats file for later
- * processing.
- *
- * In order for this code to work, the radio must be placed in non-
- * interactive mode using the "off" command and with a single <cr>
- * resonse using the "term cr" command. The setting of the "echo"
- * and "df" commands does not matter. The radio should select UTC
- * timescale using the "ts utc" command.
- *
- * There are two modes of operation for this driver. The first with
- * default configuration is used with stock kernels and serial-line
- * drivers and works with almost any machine. In this mode the driver
- * assumes the radio captures a timestamp upon receipt of the "*" that
- * begins the driver query. Accuracies in this mode are in the order of
- * a millisecond or two and the receiver can be connected to only one
- * host.
- *
- * The second mode of operation can be used for SunOS kernels that have
- * been modified with the ppsclock streams module included in this
- * distribution. The mode is enabled if flag3 of the fudge configuration
- * command has been set to 1. In this mode a precise timestamp is
- * available using a gadget box and 1-pps signal from the receiver. This
- * improves the accuracy to the order of a few tens of microseconds. In
- * addition, the serial output and 1-pps signal can be bussed to
- * additional receivers.

- * This driver furnishes an interface for pulse-per-second (PPS) signals
- * produced by a cesium clock, timing receiver or related  equipment. It
- * can be used to remove accumulated jitter and retime a secondary
- * server when synchronized to a primary server over a congested, wide-
- * area network and before redistributing the time to local clients.
- *
- * In order for this driver to work, the local clock must be set to
- * within +-500 ms by another means, such as a radio clock or NTP
- * itself. The 1-pps signal is connected via a serial port and gadget
- * box consisting of a one-shot and RS232 level converter. When operated
- * at 38.4 kbps with a SPARCstation IPC, this arrangement has a worst-
- * case jitter less than 26 us.
- *
- * There are three ways in which this driver can be used. The first way
- * uses the LDISC_PPS line discipline and works only for the baseboard
- * serial ports of the Sun SPARCstation. The PPS signal is connected via
- * a gadget box to the carrier detect (CD) line of a serial port and
- * flag3 of the driver configured for that port is set. This causes the
- * ppsclock streams module to be configured for that port and capture a
- * timestamp at the on-time transition of the PPS signal. This driver
- * then reads the timestamp directly by a designated ioctl() system
- * call. This provides the most accurate time and least jitter of any
- * other scheme. There is no need to configure a dedicated device for
- * this purpose, which ordinarily is the device used for the associated
- * radio clock.
- *
- * The second way uses the LDISC_CLKPPS line discipline and works for
- * any architecture supporting a serial port. If after a few seconds
- * this driver finds no ppsclock module configured, it attempts to open
- * a serial port device /dev/pps%d, where %d is the unit number, and
- * assign the LDISC_CLKPPS line discipline to it. If the line discipline
- * fails, no harm is done except the accuracy is reduced somewhat. The
- * pulse generator in the gadget box is adjusted to produce a start bit
- * of length 26 usec at 38400 bps. Used with the LDISC_CLKPPS line
- * discipline, this produces an ASCII DEL character ('\377') followed by
- * a timestamp at each seconds epoch.
- *
- * The third way involves an auxiliary radio clock driver which calls
- * the PPS driver with a timestamp captured by that driver. This use is
- * documented in the source code for the driver(s) involved.
- *
- * Fudge Factors
- *
- * There are no special fudge factors other than the generic and those
- * explicitly defined above. The fudge time1 parameter can be used to
- * compensate for miscellaneous UART and OS delays. Allow about 247 us
- * for uart delays at 38400 bps and about 1 ms for SunOS streams
- * nonsense.

- * The CHU time signal includes a time code which is modulated at the
- * standard Bell 103 frequencies (i.e. mark=2225Hz, space=2025Hz).
- * and formatted into 8 bit characters with one start bit and two
- * stop bits. The time code is composed of 10 8-bit characters.
- * The second 5 bytes of the timecode are a redundancy check, and
- * are a copy of the first 5 bytes.
- *
- * It is assumed that you have built or modified a Bell 103 standard
- * modem, attached the input to the output of a radio and cabled the
- * output to a serial port on your computer, i.e. what you are receiving
- * is essentially the output of your radio.  It is also assumed you have
- * installed a special CHU line discipline to condition the output from
- * the terminal driver and take accurate time stamps.
- *
- * There are two types of timecodes. One is sent in the 32nd
- * through 39th second of the minute.
- *
- *     6dddhhmmss6dddhhmmss
- *
- * where ddd is the day of the year, hh is the hour (in UTC), mm is
- * the minute and ss the second.  The 6 is a constant.  Note that
- * the code is sent twice.
- *
- * The second sort of timecode is sent only during the 31st second
- * past the minute.
- *
- *     xdyyyyttabXDYYYYTTAB
- *
- * In this case, the second part of the code is the one's complement
- * of the code. This differentiates it from the other timecode
- * format.
- *
- * d is the absolute value of DUT (in tenths of a second). yyyy
- * is the year. tt is the difference between UTC and TAI. a is
- * a canadian daylight time flag and b is a serial number.
- * x is a bitwise field. The least significant bit of x is
- * one if DUT is negative. The 2nd bit is set if a leap second
- * will be added at the next opportunity. The 3rd bit is set if
- * a leap second will be deleted at the next opportunity.
- * The 4th bit is an even parity bit for the other three bits
- * in this nibble.
- *
- * The start bit in each character has a precise relationship to
- * the on-time second. Most often UART's synchronize themselves to the
- * start bit and will post an interrupt at the center of the first stop
- * bit.  Thus each character's interrupt should occur at a fixed offset
- * from the on-time second. This means that a timestamp taken at the
- * arrival of each character in the code will provide an independent
- * estimate of the offset.  Since there are 10 characters in the time
- * code and the code is sent 9 times per minute, this means you
- * potentially get 90 offset samples per minute. Much of the code in
- * here is dedicated to producing a single offset estimate from these
- * samples.
- *
- * A note about the line discipline. It is possible to receive the
- * CHU time code in raw mode, but this has disadvantages. In particular,
- * this puts a lot of code between the interrupt and the time you freeze
- * a time stamp, decreasing precision. It is also expensive in terms of
- * context switches, and made even more expensive by the way I do I/O.
- * Worse, since you are listening directly to the output of your radio,
- * CHU is noisy and will make you spend a lot of time receiving noise.
- *
- * The line discipline fixes a lot of this. It knows that the CHU time
- * code consists of 10 bytes which arrive with an intercharacter
- * spacing of about 37 ms, and that the data is BCD, and filters on this
- * basis. It delivers block of ten characters plus their associated time
- * stamps all at once. The time stamps are hence about as accurate as
- * a Unix machine can get them, and much of the noise disappears in the
- * kernel with no context switching cost.
- *
- * The kernel module also will insure that the packets that are
- * delivered have the correct redundancy bytes, and will return
- * a flag in chutype to differentiate one sort of packet from
- * the other.

- * Support for Kinemetrics Truetime 468-DC GOES Receiver
- *   OM-DC OMEGA and GPS-TM/TMD support in progress...
- *
- * Most of this code is originally from refclock_wwvb.c with thanks.
- * It has been so mangled that wwvb is not a recognizable ancestor.
- *
- * Timcode format: ADDD:HH:MM:SSQCL
- *	A - control A
- *	Q Quality indication: indicates possible error of
- *	C - Carriage return
- *	L - Line feed
- *
- * Quality codes indicate possible error of
- *   468-DC GOES Receiver:
- *   GPS-TM/TMD Receiver:
- *       ?     +/- 500 milliseconds	#     +/- 50 milliseconds
- *       *     +/- 5 milliseconds	.     +/- 1 millisecond
- *     space   less than 1 millisecond
- *   OM-DC OMEGA Receiver:
- *       >     >+- 5 seconds
- *       ?     >+/- 500 milliseconds    #     >+/- 50 milliseconds
- *       *     >+/- 5 milliseconds      .     >+/- 1 millisecond
- *      A-H    less than 1 millisecond.  Character indicates which station
- *             is being received as follows:
- *             A = Norway, B = Liberia, C = Hawaii, D = North Dakota,
- *             E = La Reunion, F = Argentina, G = Australia, H = Japan.
- *
- * The carriage return start bit begins on 0 seconds and extends to 1
- * bit time
- *
- * Notes on 468-DC and OMEGA receiver:
- *
- * Send the clock a 'R' or 'C' and once per second a timestamp will
- * appear.  Send a 'P' to get the satellite position once.
- *
- * Notes on the 468-DC receiver:
- *
- * Unless you live on 125 degrees west longitude, you can't
- * set your clock propagation delay settings correctly and still use
- * automatic mode. The manual says to use a compromise when setting the
- * switches. This results in significant errors. The solution; use fudge
- * time1 and time2 to incorporate corrections. If your clock is set for
- * 50 and it should be 58 for using the west and 46 for using the east,
- * use the line
- *
- * fudge 127.127.5.0 time1 +0.008 time2 -0.004
- *
- * This corrects the 4 milliseconds advance and 8 milliseconds retard
- * needed. The software will ask the clock which satellite it sees.
- *
- * Ntp.conf parameters:
- * time1 - offset applied to samples when reading WEST satellite (default = 0)
- * time2 - offset applied to samples when reading EAST satellite (default = 0)
- * val1  - stratum to assign to this clock (default = 0)
- * val2  - refid assigned to this clock (default = "GOES", see below)
- * flag1 - will silence the clock side of xntpd, just reading the clock
- *         without trying to write to it.  (default = 0)
- * flag2 - not assigned
- * flag3 - enable ppsclock streams module
- * flag4 - not assigned

-/*
- * This driver supports the Heath GC-1000 Most Accurate Clock, with
- * RS232C Output Accessory. This is a WWV/WWVH receiver somewhat less
- * robust than other supported receivers. Its claimed accuracy is 100 ms
- * when actually synchronized to the broadcast signal, but this doesn't
- * happen even most of the time, due to propagation conditions, ambient
- * noise sources, etc. When not synchronized, the accuracy is at the
- * whim of the internal clock oscillator, which can wander into the
- * sunset without warning. Since the indicated precision is 100 ms,
- * expect a host synchronized only to this thing to wander to and fro,
- * occasionally being rudely stepped when the offset exceeds the default
- * CLOCK_MAX of 128 ms.
- *
- * The internal DIPswitches should be set to operate at 1200 baud in
- * MANUAL mode and the current year. The external DIPswitches should be
- * set to GMT and 24-hour format, or to the host local time zone (with
- * DST) and 12-hour format. It is very important that the year be
- * set correctly in the DIPswitches. Otherwise, the day of year will be
- * incorrect after 28 April of a normal or leap year.  In 12-hour mode
- * with DST selected the clock will be incorrect by an hour for an
- * indeterminate amount of time between 0000Z and 0200 on the day DST
- * changes.
- *
- * In MANUAL mode the clock responds to a rising edge of the request to
- * send (RTS) modem control line by sending the timecode. Therefore, it
- * is necessary that the operating system implement the TIOCMBIC and
- * TIOCMBIS ioctl system calls and TIOCM_RTS control bit. Present
- * restrictions require the use of a POSIX-compatible programming
- * interface, although other interfaces may work as well.
- *
- * A simple hardware modification to the clock can be made which
- * prevents the clock hearing the request to send (RTS) if the HI SPEC
- * lamp is out. Route the HISPEC signal to the tone decoder board pin
- * 19, from the display, pin 19. Isolate pin 19 of the decoder board
- * first, but maintain connection with pin 10. Also isolate pin 38 of
- * the CPU on the tone board, and use half an added 7400 to gate the
- * original signal to pin 38 with that from pin 19.
- *
- * The clock message consists of 23 ASCII printing characters in the
- * following format:
- *
- * hh:mm:ss.f AM  dd/mm/yr<cr>
- *
- *	hh:mm:ss.f = hours, minutes, seconds
- *	f = deciseconds ('?' when out of spec)
- *	AM/PM/bb = blank in 24-hour mode
- *	dd/mm/yr = day, month, year
- *
- * The alarm condition is indicated by '?', rather than a digit, at f.
- * Note that 0?:??:??.? is displayed before synchronization is first
- * established and hh:mm:ss.? once synchronization is established and
- * then lost again for about a day.
- *
- * Fudge Factors
- *
- * A fudge time1 value of .04 s appears to center the clock offset
- * residuals. The fudge time2 parameter is the local time offset east of
- * Greenwich, which depends on DST. Sorry about that, but the clock
- * gives no hint on what the DIPswitches say.

- * code format, and status is a status bute, The decoded timestamp is a
- * 13-octet, null-terminated ASCII string "ddd hh:mm:ss*", where ddd is
- * the day of year, hh:mm:ss the time of day and * is a status
- * indicator, with " " indicating valid time and "?" indicating
- * something wrong.
- *
- * The timestamp is in Unix timeval format, consisting of two 32-bit
- * words, the first of which is the seconds since 1970 and the second is
- * the fraction of the second in microseconds. The status byte is zero
- * if (a) the input signal is within amplitude tolerances, (b) the raw
- * binary timecode contains only valid code elements, (c) 11 position
- * identifiers have been found at the expected element positions, (d)
- * the clock status byte contained in the timecode is valid, and (e) a
- * time determination has been made since the last read() system call.
- *
- * The 100 elements of the IRIG-B timecode are numbered from 0 through
- * 99. Position identifiers occur at elements 0, 9, 19 and every ten
- * thereafter to 99. The control function (CF) elements begin at element
- * 50 (CF 1) and extend to element 78 (CF 27). The straight-binary-
- * seconds (SBS) field, which encodes the seconds of the UTC day, begins
- * at element 80 (CF 28) and extends to element 97 (CF 44). The encoding
- * of elements 50 (CF 1) through 78 (CF 27) is device dependent. This
- * driver presently does not use the CF elements.
- *
- * Where feasible, the interface should be operated with signature
- * control, so that, if the IRIG signal is lost or malformed, the
- * interface produces an unmodulated signal, rather than possibly random
- * digits. The driver will declare "unsynchronized" in this case.

-/*
- * This is a hack to allow a machine to use its own system clock as a
- * reference clock, i.e., to free-run using no outside clock discipline
- * source. This is useful if you want to use NTP in an isolated
- * environment with no radio clock or NIST modem available. Pick a
- * machine that you figure has a good clock oscillator and configure it
- * with this driver. Set the clock using the best means available, like
- * eyeball-and-wristwatch. Then, point all the other machines at this
- * one or use broadcast (not multicast) mode to distribute time.
- *
- * Another application for this driver is if you want to use a
- * particular server's clock as the clock of last resort when all other
- * normal synchronization sources have gone away. This is especially
- * useful if that server has an ovenized oscillator. For this you would
- * configure this driver at a higher stratum (say 3 or 4) to prevent the
- * server's stratum from falling below that.
- *
- * A third application for this driver is when an external discipline
- * source is available, such as the NIST "lockclock" program, which
- * synchronizes the local clock via a telephone modem and the NIST
- * Automated Computer Time Service (ACTS), or the Digital Time
- * Synchronization Service (DTSS), which runs on DCE machines. In this
- * case the stratum should be set at zero, indicating a bona fide
- * stratum-1 source. Exercise some caution with this, since there is no
- * easy way to telegraph via NTP that something might be wrong in the
- * discipline source itself. In the case of DTSS, the local clock can
- * have a rather large jitter, depending on the interval between
- * corrections and the intrinsic frequency error of the clock
- * oscillator. In extreme cases, this can cause clients to exceed the
- * 128-ms slew window and drop off the NTP subnet.
- *
- * In the default mode the behavior of the clock selection algorithm is
- * modified when this driver is in use. The algorithm is designed so
- * that this driver will never be selected unless no other discipline
- * source is available. This can be overriden with the prefer keyword of
- * the server configuration command, in which case only this driver will
- * be selected for synchronization and all other discipline sources will
- * be ignored. This behavior is intended for use when an external
- * discipline source controls the system clock.
- *
- * Fudge Factors
- *
- * The stratum for this driver LCLSTRATUM is set at 3 by default, but
- * can be changed by the fudge command and/or the xntpdc utility. The
- * reference ID is "LCL" by default, but can be changed using the same
- * mechanisms. *NEVER* configure this driver to operate at a stratum
- * which might possibly disrupt a client with access to a bona fide
- * primary server, unless athe local clock oscillator is reliably
- * disciplined by another source. *NEVER NEVER* configure a server which
- * might devolve to an undisciplined local clock to use multicast mode.
- *
- * This driver provides a mechanism to trim the local clock in both time
- * and frequency, as well as a way to manipulate the leap bits. The
- * fudge time1 parameter adjusts the time, in seconds, and the fudge
- * time2 parameter adjusts the frequency, in ppm. Both parameters are
- * additive; that is, they add increments in time or frequency to the
- * present values. The fudge flag1 and fudge flag2 bits set the
- * corresponding leap bits; for example, setting flag1 causes a leap
- * second to be added at the end of the UTC day. These bits are not
- * reset automatically when the leap takes place; they must be turned
- * off manually after the leap event.

-/*
- * This driver supports the Trimble SVee Six Plus GPS receiver module.
- * It should support other Trimble receivers which use the Trimble Standard
- * Interface Protocol (see below).
- *
- * The module has a serial I/O port for command/data and a 1 pulse-per-second
- * output, about 1 microsecond wide. The leading edge of the pulse is
- * coincident with the change of the GPS second. This is the same as
- * the change of the UTC second +/- ~1 microsecond. Some other clocks
- * specifically use a feature in the data message as a timing reference, but
- * the SVee Six Plus does not do this. In fact there is considerable jitter
- * on the timing of the messages, so this driver only supports the use
- * of the PPS pulse for accurate timing. Where it is determined that
- * the offset is way off, when first starting up xntpd for example,
- * the timing of the data stream is used until the offset becomes low enough
- * (|offset| < CLOCK_MAX), at which point the pps offset is used.
- *
- * It can use either option for receiving PPS information - the 'ppsclock'
- * stream pushed onto the serial data interface to timestamp the Carrier
- * Detect interrupts, where the 1PPS connects to the CD line. This only
- * works on SunOS 4.1.x currently. To select this, define PPSPPS in
- * Config.local. The other option is to use a pulse-stretcher/level-converter
- * to convert the PPS pulse into a RS232 start pulse & feed this into another
- * tty port. To use this option, define PPSCLK in Config.local. The pps input,
- * by whichever method, is handled in ntp_loopfilter.c
- *
- * The receiver uses a serial message protocol called Trimble Standard
- * Interface Protocol (it can support others but this driver only supports
- * TSIP). Messages in this protocol have the following form:
- *
- * <DLE><id> ... <data> ... <DLE><ETX>
- *
- * Any bytes within the <data> portion of value 10 hex (<DLE>) are doubled
- * on transmission and compressed back to one on reception. Otherwise
- * the values of data bytes can be anything. The serial interface is RS-422
- * asynchronous using 9600 baud, 8 data bits with odd party (**note** 9 bits
- * in total!), and 1 stop bit. The protocol supports byte, integer, single,
- * and double datatypes. Integers are two bytes, sent most significant first.
- * Singles are IEEE754 single precision floating point numbers (4 byte) sent
- * sign & exponent first. Doubles are IEEE754 double precision floating point
- * numbers (8 byte) sent sign & exponent first.
- * The receiver supports a large set of messages, only a small subset of
- * which are used here. From driver to receiver the following are used:
- *
- *  ID    Description
- *
- *  21    Request current time
- *  22    Mode Select
- *  2C    Set/Request operating parameters
- *  2F    Request UTC info
- *  35    Set/Request I/O options
-
- * From receiver to driver the following are recognised:
- *
- *  ID    Description
- *
- *  41    GPS Time
- *  44    Satellite selection, PDOP, mode
- *  46    Receiver health
- *  4B    Machine code/status
- *  4C    Report operating parameters (debug only)
- *  4F    UTC correction data (used to get leap second warnings)
- *  55    I/O options (debug only)
- *
- * All others are accepted but ignored.

- * This driver supports the PSTI 1010 and Traconex 1020 WWV/WWVH
- * Receivers. No specific claim of accuracy is made for these receiver,
- * but actual experience suggests that 10 ms would be a conservative
- * assumption.
- *
- * The DIPswitches should be set for 9600 bps line speed, 24-hour day-
- * of-year format and UTC time zone. Automatic correction for DST should
- * be disabled. It is very important that the year be set correctly in
- * the DIPswitches; otherwise, the day of year will be incorrect after
- * 28 April of a normal or leap year. The propagation delay DIPswitches
- * should be set according to the distance from the transmitter for both
- * WWV and WWVH, as described in the instructions. While the delay can
- * be set only to within 11 ms, the fudge time1 parameter can be used
- * for vernier corrections.
- *
- * Using the poll sequence QTQDQM, the response timecode is in three
- * sections totalling 50 ASCII printing characters, as concatenated by
- * the driver, in the following format:
- *
- * ahh:mm:ss.fffs<cr> yy/dd/mm/ddd<cr> frdzycchhSSFTttttuuxx<cr>
- *
- *	on-time = first <cr> *	hh:mm:ss.fff = hours, minutes, seconds, milliseconds
- *	a = AM/PM indicator (' ' for 24-hour mode)
- *	yy = year (from internal switches)
- *	dd/mm/ddd = day of month, month, day of year
- *	s = daylight-saving indicator (' ' for 24-hour mode)
- *	f = frequency enable (O = all frequencies enabled)
- *	r = baud rate (3 = 1200, 6 = 9600)
- *	d = features indicator (@ = month/day display enabled)
- *	z = time zone (0 = UTC)
- *	y = year (5 = 91)
- *	cc = WWV propagation delay (52 = 22 ms)
- *	hh = WWVH propagation delay (81 = 33 ms)
- *	SS = status (80 or 82 = operating correctly)
- *	F = current receive frequency (4 = 15 MHz)
- *	T = transmitter (C = WWV, H = WWVH)
- *	tttt = time since last update (0000 = minutes)
- *	uu = flush character (03 = ^c)
- *	xx = 94 (unknown)
- *
- * The alarm condition is indicated by other than '8' at A, which occurs
- * during initial synchronization and when received signal is lost for
- * an extended period; unlock condition is indicated by other than
- * "0000" in the tttt subfield at Q.
- *
- * Fudge Factors
- *
- * There are no special fudge factors other than the generic.

- * This driver supports the TRAK 8820 GPS Station Clock. The claimed
- * accuracy at the 1-pps output is 200-300 ns relative to the broadcast
- * signal; however, in most cases the actual accuracy is limited by the
- * precision of the timecode and the latencies of the serial interface
- * and operating system.
- *
- * For best accuracy, this radio requires the LDISC_ACTS line
- * discipline, which captures a timestamp at the '*' on-time character
- * of the timecode. Using this discipline the jitter is in the order of
- * 1 ms and systematic error about 0.5 ms. If unavailable, the buffer
- * timestamp is used, which is captured at the \r ending the timecode
- * message. This introduces a systematic error of 23 character times, or
- * about 24 ms at 9600 bps, together with a jitter well over 8 ms on Sun
- * IPC-class machines.
- *
- * Using the memus, the radio should be set for 9600 bps, one stop bit
- * and no parity. It should be set to operate in computer (no echo)
- * mode. The timecode format includes neither the year nor leap-second
- * warning. No provisions are included in this preliminary version of
- * the driver to read and record detailed internal radio status.
- *
- * In operation, this driver sends a RQTS\r request to the radio at
- * initialization in order to put it in continuous time output mode. The
- * radio then sends the following message once each second:
- *
- *	*RQTS U,ddd:hh:mm:ss.0,q<cr><lf>
- *
- *	on-time = '*' *	ddd = day of year
- *	hh:mm:ss = hours, minutes, seconds

- * 		0 > 20 us

- * The alarm condition is indicated by '0' at Q, which means the radio
- * has a phase error than 20 usec relative to the broadcast time. The
- * absence of year, DST and leap-second warning in this format is also
- * alarming.
- *
- * The continuous time mode is disabled using the RQTX<cr> request,
- * following which the radio sends a RQTX DONE<cr><lf> response. In the
- * normal mode, other control and status requests are effective,
- * including the leap-second status request RQLS<cr>. The radio responds
- * wtih RQLS yy,mm,dd<cr><lf>, where yy,mm,dd are the year, month and
- * day. Presumably, this gives the epoch of the next leap second,
- * RQLS 00,00,00 if none is specified in the GPS message. Specified in
- * this form, the information is generally useless and is ignored by
- * the driver.
- *
- * Fudge Factors
- *
- * There are no special fudge factors other than the generic.

-/*
- * This driver supports the Spectracom Model 8170 and Netclock/2 WWVB
- * Synchronized Clock. This clock has proven a reliable source of time,
- * except in some cases of high ambient conductive RF interference. The
- * claimed accuracy of the clock is 100 usec relative to the broadcast
- * signal; however, in most cases the actual accuracy is limited by the
- * precision of the timecode and the latencies of the serial interface
- * and operating system.
- *
- * The DIPswitches on this clock should be set to 24-hour display, AUTO
- * DST off, time zone 0 (UTC), data format 0 or 2 (see below) and baud
- * rate 9600. If this clock is to used as the source for the IRIG Audio
- * Decoder (refclock_irig.c in this distribution), set the DIPswitches
- * for AM IRIG output and IRIG format 1 (IRIG B with signature control).
- *
- * There are two timecode formats used by these clocks. Format 0, which
- * is available with both the Netclock/2 and 8170, and format 2, which
- * is available only with the Netclock/2 and specially modified 8170.
- *
- * Format 0 (22 ASCII printing characters):
- *
- * <cr><lf>i  ddd hh:mm:ss  TZ=zz<cr><lf>
- *
- *	on-time = first <cr> *	hh:mm:ss = hours, minutes, seconds
- *	i = synchronization flag (' ' = in synch, '?' = out of synch)
- *
- * The alarm condition is indicated by other than ' ' at A, which occurs
- * during initial synchronization and when received signal is lost for
- * about ten hours.
- *
- * Format 2 (24 ASCII printing characters):
- *
- * <cr><lf>iqyy ddd hh:mm:ss.fff ld
- *
- *	on-time = <cr>
- *	i = synchronization flag (' ' = in synch, '?' = out of synch)
- *	q = quality indicator (' ' = locked, 'A'...'D' = unlocked)
- *	yy = year (as broadcast)
- *	ddd = day of year
- *	hh:mm:ss.fff = hours, minutes, seconds, milliseconds
- *
- * The alarm condition is indicated by other than ' ' at A, which occurs
- * during initial synchronization and when received signal is lost for
- * about ten hours. The unlock condition is indicated by other than ' '
- * at Q.
- *
- * The Q is normally ' ' when the time error is less than 1 ms and a
- * character in the set 'A'...'D' when the time error is less than 10,
- * 100, 500 and greater than 500 ms respectively. The L is normally ' ',
- * but is set to 'L' early in the month of an upcoming UTC leap second
- * and reset to ' ' on the first day of the following month. The D is
- * set to 'S' for standard time 'I' on the day preceding a switch to
- * daylight time, 'D' for daylight time and 'O' on the day preceding a
- * switch to standard time. The start bit of the first <cr> is
- * synchronized to the indicated time as returned.
- *
- * This driver does not need to be told which format is in use - it
- * figures out which one from the length of the message. A three-stage
- * median filter is used to reduce jitter and provide a dispersion
- * measure. The driver makes no attempt to correct for the intrinsic
- * jitter of the radio itself, which is a known problem with the older
- * radios.
- *
- * Fudge Factors
- *
- * This driver can retrieve a table of quality data maintained
- * internally by the Netclock/2 receiver. If flag4 of the fudge
- * configuration command is set to 1, the driver will retrieve this
- * table and write it to the clockstats file on when the first timecode
- * message of a new day is received.
