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.

26 # for handling POSIX-style time zone environment variables,

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

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.

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
