6# Change the line below for your time zone (after finding the zone you want in
7# the time zone files, or adding it to a time zone file).
8# Alternately, if you discover you've got the wrong time zone, you can just
9#	zic -l rightzone
10# to correct things.

17# If you want something other than Eastern United States time as a template
18# for handling POSIX-style time zone environment variables,
19# change the line below (after finding the zone you want in the
20# time zone files, or adding it to a time zone file).
21# (When a POSIX-style environment variable is handled, the rules in the
22# template file are used to determine "spring forward" and "fall back" days and
23# times; the environment variable itself specifies UTC offsets of standard and
24# summer time.)
25# Alternately, if you discover you've got the wrong time zone, you can just
26#	zic -p rightzone
27# to correct things.

126# If you want to use System V compatibility code, add
127#	-DUSG_COMPAT
128# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
129# variables to be kept up-to-date by the time conversion functions.  Neither
130# "timezone" nor "daylight" is described in X3J11's work.
131#
132# If your system has a "GMT offset" field in its "struct tm"s
133# (or if you decide to add such a field in your system's "time.h" file),
134# add the name to a define such as
135#	-DTM_GMTOFF=tm_gmtoff
136# or
137#	-DTM_GMTOFF=_tm_gmtoff
138# to the end of the "CFLAGS=" line.
139# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
140# in its work, use of "tm_gmtoff" is described as non-conforming.
141# Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
142# their recent releases.
143#
144# If your system has a "zone abbreviation" field in its "struct tm"s
145# (or if you decide to add such a field in your system's "time.h" file),
146# add the name to a define such as
147#	-DTM_ZONE=tm_zone
148# or
149#	-DTM_ZONE=_tm_zone
150# to the end of the "CFLAGS=" line.
151# Neither tm_zone nor _tm_zone is described in X3J11's work;
152# in its work, use of "tm_zone" is described as non-conforming.
153# Both UCB and Sun have done the equivalent of defining TM_ZONE in
154# their recent releases.
155#
156# If you want functions that were inspired by early versions of X3J11's work,
157# add
158#	-DSTD_INSPIRED
159# to the end of the "CFLAGS=" line.  This arranges for the functions
160# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
161# "posix2time", and "time2posix" to be added to the time conversion library.
162# "tzsetwall" is like "tzset" except that it arranges for local wall clock
163# time (rather than the time specified in the TZ environment variable)
164# to be used.
165# "offtime" is like "gmtime" except that it accepts a second (long) argument
166# that gives an offset to add to the time_t when converting it.
167# "timelocal" is equivalent to "mktime".
168# "timegm" is like "timelocal" except that it turns a struct tm into
169# a time_t using UTC (rather than local time as "timelocal" does).
170# "timeoff" is like "timegm" except that it accepts a second (long) argument
171# that gives an offset to use when converting to a time_t.
172# "posix2time" and "time2posix" are described in an included manual page.
173# X3J11's work does not describe any of these functions.
174# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
175# These functions may well disappear in future releases of the time
176# conversion package.
177#
178# If you want Source Code Control System ID's left out of object modules, add
179#	-DNOID
180# to the end of the "CFLAGS=" line.
181#
182# If you'll never want to handle solar-time-based time zones, add
183#	-DNOSOLAR
184# to the end of the "CFLAGS=" line
185# (and comment out the "SDATA=" line below).
186# This reduces (slightly) the run-time data-space requirements of
187# the time conversion functions; it may reduce the acceptability of your system
188# to folks in oil- and cash-rich places.
189#
190# If you want to allocate state structures in localtime, add
191#	-DALL_STATE
192# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
193#
194# If you want an "altzone" variable (a la System V Release 3.1), add
195#	-DALTZONE
196# to the end of the "CFLAGS=" line.
197# This variable is not described in X3J11's work.
198#
199# If you want a "gtime" function (a la MACH), add
200#	-DCMUCS
201# to the end of the "CFLAGS=" line
202# This function is not described in X3J11's work.
203#
204# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put

207#	-DPCTS
208# to the end of the "CFLAGS=" line.
209#
210# If you want strict compliance with XPG4 as of 1994-04-09, add
211#	-DXPG4_1994_04_09
212# to the end of the "CFLAGS=" line.  This causes "strftime" to always return
213# 53 as a week number (rather than 52 or 53) for those days in January that
214# before the first Monday in January when a "%V" format is used and January 1
215# falls on a Friday, Saturday, or Sunday.
