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

 151 # variables to be kept up-to-date by the time conversion functions.  Neither
 152 # "timezone" nor "daylight" is described in X3J11's work.
 153 #
 154 # If your system has a "GMT offset" field in its "struct tm"s
 155 # (or if you decide to add such a field in your system's "time.h" file),
 156 # add the name to a define such as
 157 #       -DTM_GMTOFF=tm_gmtoff
 158 # or
 159 #       -DTM_GMTOFF=_tm_gmtoff
 160 # to the end of the "CFLAGS=" line.
 161 # Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
 162 # in its work, use of "tm_gmtoff" is described as non-conforming.
 163 # Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
 164 # their recent releases.
 165 #
 166 # If your system has a "zone abbreviation" field in its "struct tm"s
 167 # (or if you decide to add such a field in your system's "time.h" file),
 168 # add the name to a define such as
 169 #       -DTM_ZONE=tm_zone
 170 # or
 171 #       -DTM_ZONE=_tm_zone
 172 # to the end of the "CFLAGS=" line.
 173 # Neither tm_zone nor _tm_zone is described in X3J11's work;
 174 # in its work, use of "tm_zone" is described as non-conforming.
 175 # Both UCB and Sun have done the equivalent of defining TM_ZONE in
 176 # their recent releases.
 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'll never want to handle solar-time-based time zones, add
 201 #       -DNOSOLAR
 202 # to the end of the "CFLAGS=" line
 203 # (and comment out the "SDATA=" line below).
 204 # This reduces (slightly) the run-time data-space requirements of
 205 # the time conversion functions; it may reduce the acceptability of your system
 206 # to folks in oil- and cash-rich places.
 207 #
 208 # If you want to allocate state structures in localtime, add
 209 #       -DALL_STATE
 210 # to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
 211 #
 212 # If you want an "altzone" variable (a la System V Release 3.1), add
 213 #       -DALTZONE
 214 # to the end of the "CFLAGS=" line.
 215 # This variable is not described in X3J11's work.
 216 #
 217 # If you want a "gtime" function (a la MACH), add
 218 #       -DCMUCS
 219 # to the end of the "CFLAGS=" line
 220 # This function is not described in X3J11's work.
