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

180 # Similarly, if your system has a "zone abbreviation" field, define
182 # and define NO_TM_ZONE to suppress any guessing. These two fields are not

189 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
190 # "posix2time", and "time2posix" to be added to the time conversion library.
191 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
192 # time (rather than the time specified in the TZ environment variable)
194 # "offtime" is like "gmtime" except that it accepts a second (long) argument
195 # that gives an offset to add to the time_t when converting it.
196 # "timelocal" is equivalent to "mktime".
197 # "timegm" is like "timelocal" except that it turns a struct tm into
198 # a time_t using UT (rather than local time as "timelocal" does).
199 # "timeoff" is like "timegm" except that it accepts a second (long) argument
200 # that gives an offset to use when converting to a time_t.
201 # "posix2time" and "time2posix" are described in an included manual page.
202 # X3J11's work does not describe any of these functions.
203 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
204 # These functions may well disappear in future releases of the time
205 # conversion package.
207 # If you don't want functions that were inspired by NetBSD, add
208 # -DNETBSD_INSPIRED=0
209 # to the end of the "CFLAGS=" line. Otherwise, the functions
210 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
211 # time library, and if STD_INSPIRED is also defined the functions
212 # "posix2time_z" and "time2posix_z" are added as well.
213 # The functions ending in "_z" (or "_rz") are like their unsuffixed
214 # (or suffixed-by-"_r") counterparts, except with an extra first
215 # argument of opaque type timezone_t that specifies the time zone.
216 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
218 # If you want to allocate state structures in localtime, add
220 # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.
222 # If you want an "altzone" variable (a la System V Release 3.1), add
224 # to the end of the "CFLAGS=" line.
225 # This variable is not described in X3J11's work.

229 # which claims to test C and Posix conformance. If you want to pass PCTS, add
231 # to the end of the "CFLAGS=" line.
233 # If you want strict compliance with XPG4 as of 1994-04-09, add
235 # to the end of the "CFLAGS=" line. This causes "strftime" to always return
