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 UTC 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.

140# If you want to use System V compatibility code, add
141#	-DUSG_COMPAT
142# to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
143# variables to be kept up-to-date by the time conversion functions.  Neither
144# "timezone" nor "daylight" is described in X3J11's work.
145#
146# If your system has a "GMT offset" field in its "struct tm"s
147# (or if you decide to add such a field in your system's "time.h" file),
148# add the name to a define such as
149#	-DTM_GMTOFF=tm_gmtoff
150# or
151#	-DTM_GMTOFF=_tm_gmtoff
152# to the end of the "CFLAGS=" line.
153# Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
154# in its work, use of "tm_gmtoff" is described as non-conforming.
155# Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
156# their recent releases.
157#
158# If your system has a "zone abbreviation" field in its "struct tm"s
159# (or if you decide to add such a field in your system's "time.h" file),
160# add the name to a define such as
161#	-DTM_ZONE=tm_zone
162# or
163#	-DTM_ZONE=_tm_zone
164# to the end of the "CFLAGS=" line.
165# Neither tm_zone nor _tm_zone is described in X3J11's work;
166# in its work, use of "tm_zone" is described as non-conforming.
167# Both UCB and Sun have done the equivalent of defining TM_ZONE in
168# their recent releases.
169#
170# If you want functions that were inspired by early versions of X3J11's work,
171# add
172#	-DSTD_INSPIRED
173# to the end of the "CFLAGS=" line.  This arranges for the functions
174# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
175# "posix2time", and "time2posix" to be added to the time conversion library.
176# "tzsetwall" is like "tzset" except that it arranges for local wall clock
177# time (rather than the time specified in the TZ environment variable)
178# to be used.
179# "offtime" is like "gmtime" except that it accepts a second (long) argument
180# that gives an offset to add to the time_t when converting it.
181# "timelocal" is equivalent to "mktime".
182# "timegm" is like "timelocal" except that it turns a struct tm into
183# a time_t using UTC (rather than local time as "timelocal" does).
184# "timeoff" is like "timegm" except that it accepts a second (long) argument
185# that gives an offset to use when converting to a time_t.
186# "posix2time" and "time2posix" are described in an included manual page.
187# X3J11's work does not describe any of these functions.
188# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
189# These functions may well disappear in future releases of the time
190# conversion package.
191#
192# If you want Source Code Control System ID's left out of object modules, add
193#	-DNOID
194# to the end of the "CFLAGS=" line.
195#
196# If you'll never want to handle solar-time-based time zones, add
197#	-DNOSOLAR
198# to the end of the "CFLAGS=" line
199# (and comment out the "SDATA=" line below).
200# This reduces (slightly) the run-time data-space requirements of
201# the time conversion functions; it may reduce the acceptability of your system
202# to folks in oil- and cash-rich places.
203#
204# If you want to allocate state structures in localtime, add
205#	-DALL_STATE
206# to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
207#
208# If you want an "altzone" variable (a la System V Release 3.1), add
209#	-DALTZONE
210# to the end of the "CFLAGS=" line.
211# This variable is not described in X3J11's work.
212#
213# If you want a "gtime" function (a la MACH), add
214#	-DCMUCS
215# to the end of the "CFLAGS=" line
216# This function is not described in X3J11's work.
217#
218# NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
219# out by the National Institute of Standards and Technology
220# which claims to test C and Posix conformance.  If you want to pass PCTS, add
221#	-DPCTS
222# to the end of the "CFLAGS=" line.
223#
224# If you want strict compliance with XPG4 as of 1994-04-09, add
225#	-DXPG4_1994_04_09
226# to the end of the "CFLAGS=" line.  This causes "strftime" to always return
227# 53 as a week number (rather than 52 or 53) for those days in January that
228# before the first Monday in January when a "%V" format is used and January 1
229# falls on a Friday, Saturday, or Sunday.
