-.TH TIME2POSIX 3
-.SH NAME
-time2posix, posix2time \- convert seconds since the Epoch
-.SH SYNOPSIS
-.nf
-.B #include <sys/types.h>
-.B #include <time.h>
-.PP
-.B time_t time2posix(t)
-.B time_t t
-.PP
-.B time_t posix2time(t)
-.B time_t t
-.PP
-.B cc ... -lz
-.fi
-.SH DESCRIPTION
-IEEE Standard 1003.1
-(POSIX)
-legislates that a time_t value of
-536457599 shall correspond to "Wed Dec 31 23:59:59 GMT 1986."
-This effectively implies that POSIX time_t's cannot include leap
-seconds and,
-therefore,
-that the system time must be adjusted as each leap occurs.
-.PP
-If the time package is configured with leap-second support
-enabled,
-however,
-no such adjustment is needed and
-time_t values continue to increase over leap events
-(as a true `seconds since...' value).
-This means that these values will differ from those required by POSIX
-by the net number of leap seconds inserted since the Epoch.
-.PP
-Typically this is not a problem as the type time_t is intended
-to be
-(mostly)
-opaque\(emtime_t values should only be obtained-from and
-passed-to functions such as
-.IR time(2) ,
-.IR localtime(3) ,
-.IR mktime(3) ,
-and
-.IR difftime(3) .
-However,
-POSIX gives an arithmetic
-expression for directly computing a time_t value from a given date/time,
-and the same relationship is assumed by some
-(usually older)
-applications.
-Any programs creating/dissecting time_t's
-using such a relationship will typically not handle intervals
-over leap seconds correctly.
-.PP
-The
-.I time2posix
-and
-.I posix2time
-functions are provided to address this time_t mismatch by converting
-between local time_t values and their POSIX equivalents.
-This is done by accounting for the number of time-base changes that
-would have taken place on a POSIX system as leap seconds were inserted
-or deleted.
-These converted values can then be used in lieu of correcting the older
-applications,
-or when communicating with POSIX-compliant systems.
-.PP
-.I Time2posix
-is single-valued.
-That is,
-every local time_t
-corresponds to a single POSIX time_t.
-.I Posix2time
-is less well-behaved:
-for a positive leap second hit the result is not unique,
-and for a negative leap second hit the corresponding
-POSIX time_t doesn't exist so an adjacent value is returned.
-Both of these are good indicators of the inferiority of the
-POSIX representation.
-.PP
-The following table summarizes the relationship between a time
-T and it's conversion to,
-and back from,
-the POSIX representation over the leap second inserted at the end of June,
-1993.

-.PP
-If leap-second support is not enabled,
-local time_t's and
-POSIX time_t's are equivalent,
-and both
-.I time2posix
-and
-.I posix2time
-degenerate to the identity function.

-# From Paul Eggert <eggert@twinsun.com> (1995-11-03)
-#
-# The Web has several other sources for time zone and daylight savings data.
-# Here are some recent links that may be of interest.
-#
-# Date and Time Gateway
-#	http://www.bsdi.com/date
-# A text-based source for tables of current time throughout the world.
-# Its point-and-click interface accesses a recent version of the tz data.
-#
-# Local Times Around the World
-#	http://www.hilink.com.au/times/
-# This text-based system contains links to local time servers
-# throughout the world, and though the coverage is limited,
-# the live data provide a nice way to check one's tables.
-#
-# World Time Zones
-#	http://tycho.usno.navy.mil/tzones.html
-# US Naval Observatory data, used as the source for `usno1995'.
-#
-# Standard Time Zones of the World

-#	http://www.odci.gov/cia/publications/95fact/802389h.gif	[1317 kB]
-# A static time zone map, available in both low-resolution and
-# high-resolution versions. The quality is good, but the map does not
-# indicate summer time, and parts of the data are a few years out of date.
-#
-# VIBE's World Map
-#	http://pathfinder.com/vibe/vibeworld
-# An active time zone map. You can point to the map and find out what
-# time it is at that location. The map and data are not as good as
-# other sources.

-# To Paul's list of time zone information on the web, I would add the
-# following URL:
-#	http://www.dhl.com/dhl/dhlinfo/1bb.html
-# or more simply:
-#	http://www.dhl.com/
-# 
-# This is run by DHL (the courier company), and it presents a list of the  
-# countries served by that company.  If you then click on a particular  
-# country, here's an example of what you'll see (graphics stripped out):
-# 
-# United Kingdom
-# 
-# HOLIDAYS: Jan 1, 2, Apr 14, 17, May 1, 29, Aug 28, Dec 25, 26
-# 
-# INTERNATIONAL DIALING CODE: +44
-# 
-# CURRENT LOCAL TIME: 09:41 Monday 6 November 1995
-# 
-# I find this rather handy, and given that DHL covers 217 countries and  
-# territories, it's pretty comprehensive coverage.
-# 
-# (I have no idea what system DHL is using to calculate the local time, but  
-# it's been accurate so far.)
