163 # variables to be kept up-to-date by the time conversion functions. Neither
164 # "timezone" nor "daylight" is described in X3J11's work.
166 # If your system has a "GMT offset" field in its "struct tm"s

168 # add the name to a define such as

170 # to the end of the "CFLAGS=" line. If not defined, the code attempts to
171 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
172 # Similarly, if your system has a "zone abbreviation" field, define
174 # and define NO_TM_ZONE to suppress any guessing. These two fields are not
175 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
177 # If you want functions that were inspired by early versions of X3J11's work,
180 # to the end of the "CFLAGS=" line. This arranges for the functions
181 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
182 # "posix2time", and "time2posix" to be added to the time conversion library.
183 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
184 # time (rather than the time specified in the TZ environment variable)
186 # "offtime" is like "gmtime" except that it accepts a second (long) argument
187 # that gives an offset to add to the time_t when converting it.
188 # "timelocal" is equivalent to "mktime".
189 # "timegm" is like "timelocal" except that it turns a struct tm into
190 # a time_t using UT (rather than local time as "timelocal" does).
191 # "timeoff" is like "timegm" except that it accepts a second (long) argument
192 # that gives an offset to use when converting to a time_t.
193 # "posix2time" and "time2posix" are described in an included manual page.
194 # X3J11's work does not describe any of these functions.
195 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
196 # These functions may well disappear in future releases of the time
197 # conversion package.
199 # If you don't want functions that were inspired by NetBSD, add
200 # -DNETBSD_INSPIRED=0
201 # to the end of the "CFLAGS=" line. Otherwise, the functions
202 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
203 # time library, and if STD_INSPIRED is also defined the functions
204 # "posix2time_z" and "time2posix_z" are added as well.
205 # The functions ending in "_z" (or "_rz") are like their unsuffixed
206 # (or suffixed-by-"_r") counterparts, except with an extra first
207 # argument of opaque type timezone_t that specifies the time zone.
208 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
210 # If you want to allocate state structures in localtime, add
212 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.
214 # If you want an "altzone" variable (a la System V Release 3.1), add
216 # to the end of the "CFLAGS=" line.
217 # This variable is not described in X3J11's work.
219 # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put

223 # to the end of the "CFLAGS=" line.
225 # If you want strict compliance with XPG4 as of 1994-04-09, add
227 # to the end of the "CFLAGS=" line. This causes "strftime" to always return
228 # 53 as a week number (rather than 52 or 53) for those days in January that
