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

186 # and define NO_TM_ZONE to suppress any guessing. These two fields are not

195 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
196 # time (rather than the time specified in the TZ environment variable)
198 # "offtime" is like "gmtime" except that it accepts a second (long) argument
199 # that gives an offset to add to the time_t when converting it.
200 # "timelocal" is equivalent to "mktime".
201 # "timegm" is like "timelocal" except that it turns a struct tm into
202 # a time_t using UT (rather than local time as "timelocal" does).
203 # "timeoff" is like "timegm" except that it accepts a second (long) argument
204 # that gives an offset to use when converting to a time_t.
205 # "posix2time" and "time2posix" are described in an included manual page.
206 # X3J11's work does not describe any of these functions.
207 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
208 # These functions may well disappear in future releases of the time
209 # conversion package.
211 # If you don't want functions that were inspired by NetBSD, add
212 # -DNETBSD_INSPIRED=0
213 # to the end of the "CFLAGS=" line. Otherwise, the functions
214 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
215 # time library, and if STD_INSPIRED is also defined the functions
216 # "posix2time_z" and "time2posix_z" are added as well.
217 # The functions ending in "_z" (or "_rz") are like their unsuffixed
218 # (or suffixed-by-"_r") counterparts, except with an extra first
219 # argument of opaque type timezone_t that specifies the time zone.
220 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
222 # If you want to allocate state structures in localtime, add
224 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.
226 # If you want an "altzone" variable (a la System V Release 3.1), add
228 # to the end of the "CFLAGS=" line.
229 # This variable is not described in X3J11's work.
231 # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put
232 # out by the National Institute of Standards and Technology
233 # which claims to test C and Posix conformance. If you want to pass PCTS, add
235 # to the end of the "CFLAGS=" line.
237 # If you want strict compliance with XPG4 as of 1994-04-09, add
239 # to the end of the "CFLAGS=" line. This causes "strftime" to always return
240 # 53 as a week number (rather than 52 or 53) for those days in January that
