 161 # If you want to use System V compatibility code, add

 163 # to the end of the "CFLAGS=" line.  This arrange for "timezone" and "daylight"
 164 # variables to be kept up-to-date by the time conversion functions.  Neither
 165 # "timezone" nor "daylight" is described in X3J11's work.
 166 #
 167 # If your system has a "GMT offset" field in its "struct tm"s
 168 # (or if you decide to add such a field in your system's "time.h" file),
 169 # add the name to a define such as
 170 #       -DTM_GMTOFF=tm_gmtoff
 171 # to the end of the "CFLAGS=" line.  If not defined, the code attempts to
 172 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
 173 # Similarly, if your system has a "zone abbreviation" field, define
 174 #       -DTM_ZONE=tm_zone
 175 # and define NO_TM_ZONE to suppress any guessing.  These two fields are not
 176 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
 177 #
 178 # If you want functions that were inspired by early versions of X3J11's work,
 179 # add
 180 #       -DSTD_INSPIRED
 181 # to the end of the "CFLAGS=" line.  This arranges for the functions
 182 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
 183 # "posix2time", and "time2posix" to be added to the time conversion library.
 184 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
 185 # time (rather than the time specified in the TZ environment variable)
 186 # to be used.
 187 # "offtime" is like "gmtime" except that it accepts a second (long) argument
 188 # that gives an offset to add to the time_t when converting it.
 189 # "timelocal" is equivalent to "mktime".
 190 # "timegm" is like "timelocal" except that it turns a struct tm into
 191 # a time_t using UT (rather than local time as "timelocal" does).
 192 # "timeoff" is like "timegm" except that it accepts a second (long) argument
 193 # that gives an offset to use when converting to a time_t.
 194 # "posix2time" and "time2posix" are described in an included manual page.
 195 # X3J11's work does not describe any of these functions.
 196 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
 197 # These functions may well disappear in future releases of the time
 198 # conversion package.
 199 #
 200 # If you don't want functions that were inspired by NetBSD, add
 201 #       -DNETBSD_INSPIRED=0
 202 # to the end of the "CFLAGS=" line.  Otherwise, the functions
 203 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
 204 # time library, and if STD_INSPIRED is also defined the functions
 205 # "posix2time_z" and "time2posix_z" are added as well.
 206 # The functions ending in "_z" (or "_rz") are like their unsuffixed
 207 # (or suffixed-by-"_r") counterparts, except with an extra first
 208 # argument of opaque type timezone_t that specifies the time zone.
 209 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
 210 #
 211 # If you want to allocate state structures in localtime, add
 212 #       -DALL_STATE
 213 # to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
 214 #
 215 # If you want an "altzone" variable (a la System V Release 3.1), add
 216 #       -DALTZONE
 217 # to the end of the "CFLAGS=" line.
 218 # This variable is not described in X3J11's work.
