# Change the line below for your time zone (after finding the zone you want in
# the time zone files, or adding it to a time zone file).
# Alternately, if you discover you've got the wrong time zone, you can just

# Use the command

# If you want something other than Eastern United States time as a template
# for handling POSIX-style time zone environment variables,
# change the line below (after finding the zone you want in the
# time zone files, or adding it to a time zone file).
# (When a POSIX-style environment variable is handled, the rules in the template
# file are used to determine "spring forward" and "fall back" days and
# times; the environment variable itself specifies GMT offsets of standard and
# summer time.)
# Alternately, if you discover you've got the wrong time zone, you can just
#	zic -p rightzone
# to correct things.
# Use the command
#	make zonenames
# to get a list of the values you can use for POSIXRULES.
# If you want POSIX compatibility, use "US/Eastern".

# If you always want time values interpreted as "seconds since the epoch

# POSIX mandates that leap seconds not be counted; for compatibility with it,

YEARISTYPE=	./yearistype

# If you're on an AT&T-based system (rather than a BSD-based system), add
#	-DUSG
# to the end of the "CFLAGS=" line.
#
# If you're running on a system where "strchr" is known as "index"
# (for example, a 4.[012]BSD system), add
#	-Dstrchr=index
# to the end of the "CFLAGS=" line.
#
# If you're running on a system with a "mkdir" function, feel free to add
#	-Demkdir=mkdir
# to the end of the "CFLAGS=" line
#
# If you want to use System V compatibility code, add
#	-DUSG_COMPAT
# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
# variables to be kept up-to-date by the time conversion functions.  Neither
# "timezone" nor "daylight" is described in X3J11's work.
#
# If your system has a "GMT offset" field in its "struct tm"s
# (or if you decide to add such a field in your system's "time.h" file),
# add the name to a define such as
#	-DTM_GMTOFF=tm_gmtoff
# or
#	-DTM_GMTOFF=_tm_gmtoff
# to the end of the "CFLAGS=" line.
# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
# in its work, use of "tm_gmtoff" is described as non-conforming.
# Both UCB and Sun have done the equivalent of defining TM_GMTOFF in
# their recent releases.
#
# If your system has a "zone abbreviation" field in its "struct tm"s
# (or if you decide to add such a field in your system's "time.h" file),
# add the name to a define such as
#	-DTM_ZONE=tm_zone
# or
#	-DTM_ZONE=_tm_zone
# to the end of the "CFLAGS=" line.
# Neither tm_zone nor _tm_zone is described in X3J11's work;
# in its work, use of "tm_zone" is described as non-conforming.
# Both UCB and Sun have done the equivalent of defining TM_ZONE in
# their recent releases.
#
# If you want functions that were inspired by early versions of X3J11's work,
# add
#	-DSTD_INSPIRED
# to the end of the "CFLAGS=" line.  This arranges for the functions
# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
# "posix2time", and "time2posix" to be added to the time conversion library.
# "tzsetwall" is like "tzset" except that it arranges for local wall clock
# time (rather than the time specified in the TZ environment variable)
# to be used.
# "offtime" is like "gmtime" except that it accepts a second (long) argument
# that gives an offset to add to the time_t when converting it.
# "timelocal" is equivalent to "mktime".
# "timegm" is like "timelocal" except that it turns a struct tm into
# a time_t using GMT (rather than local time as "timelocal" does).
# "timeoff" is like "timegm" except that it accepts a second (long) argument
# that gives an offset to use when converting to a time_t.
# "posix2time" and "time2posix" are described in an included manual page.
# None of these functions are described in X3J11's current work.
# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
# These functions may well disappear in future releases of the time
# conversion package.
#
# If you want Source Code Control System ID's left out of object modules, add
#	-DNOID
# to the end of the "CFLAGS=" line.
#
# If you'll never want to handle solar-time-based time zones, add
#	-DNOSOLAR
# to the end of the "CFLAGS=" line
# (and comment out the "SDATA=" line below).
# This reduces (slightly) the run-time data-space requirements of
# the time conversion functions; it may reduce the acceptability of your system
# to folks in oil- and cash-rich places.
#
# If you want to allocate state structures in localtime, add
#	-DALL_STATE
# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
#
# If you want an "altzone" variable (a la System V Release 3.1), add
#	-DALTZONE
# to the end of the "CFLAGS=" line.
# This variable is not described in X3J11's work.
#
# If you want a "gtime" function (a la MACH), add
#	-DCMUCS
# to the end of the "CFLAGS=" line
# This function is not described in X3J11's work.
