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

20#	make zonenames

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

148# If you want to use System V compatibility code, add
149#	-DUSG_COMPAT
150# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
151# variables to be kept up-to-date by the time conversion functions.  Neither
152# "timezone" nor "daylight" is described in X3J11's work.
153#
154# If your system has a "GMT offset" field in its "struct tm"s
155# (or if you decide to add such a field in your system's "time.h" file),
156# add the name to a define such as
157#	-DTM_GMTOFF=tm_gmtoff
158# or
159#	-DTM_GMTOFF=_tm_gmtoff
160# to the end of the "CFLAGS=" line.
161# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
162# in its work, use of "tm_gmtoff" is described as non-conforming.
163# Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
164# their recent releases.
165#
166# If your system has a "zone abbreviation" field in its "struct tm"s
167# (or if you decide to add such a field in your system's "time.h" file),
168# add the name to a define such as
169#	-DTM_ZONE=tm_zone
170# or
171#	-DTM_ZONE=_tm_zone
172# to the end of the "CFLAGS=" line.
173# Neither tm_zone nor _tm_zone is described in X3J11's work;
174# in its work, use of "tm_zone" is described as non-conforming.
175# Both UCB and Sun have done the equivalent of defining TM_ZONE in
176# their recent releases.
177#
178# If you want functions that were inspired by early versions of X3J11's work,
179# add
180#	-DSTD_INSPIRED
181# to the end of the "CFLAGS=" line.  This arranges for the functions
182# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
183# "posix2time", and "time2posix" to be added to the time conversion library.
184# "tzsetwall" is like "tzset" except that it arranges for local wall clock
185# time (rather than the time specified in the TZ environment variable)
186# to be used.
187# "offtime" is like "gmtime" except that it accepts a second (long) argument
188# that gives an offset to add to the time_t when converting it.
189# "timelocal" is equivalent to "mktime".
190# "timegm" is like "timelocal" except that it turns a struct tm into
191# a time_t using UT (rather than local time as "timelocal" does).
192# "timeoff" is like "timegm" except that it accepts a second (long) argument
193# that gives an offset to use when converting to a time_t.
194# "posix2time" and "time2posix" are described in an included manual page.
195# X3J11's work does not describe any of these functions.
196# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
197# These functions may well disappear in future releases of the time
198# conversion package.
199#
200# If you want to allocate state structures in localtime, add
201#	-DALL_STATE
202# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
203#
204# If you want an "altzone" variable (a la System V Release 3.1), add
205#	-DALTZONE
206# to the end of the "CFLAGS=" line.
207# This variable is not described in X3J11's work.
208#
209# If you want a "gtime" function (a la MACH), add
210#	-DCMUCS
211# to the end of the "CFLAGS=" line
212# This function is not described in X3J11's work.

217#	-DPCTS
218# to the end of the "CFLAGS=" line.
219#
220# If you want strict compliance with XPG4 as of 1994-04-09, add
221#	-DXPG4_1994_04_09
222# to the end of the "CFLAGS=" line.  This causes "strftime" to always return
223# 53 as a week number (rather than 52 or 53) for those days in January that
