 131 # variables to be kept up-to-date by the time conversion functions.  Neither
 132 # "timezone" nor "daylight" is described in X3J11's work.
 133 #
 134 # If your system has a "GMT offset" field in its "struct tm"s
 135 # (or if you decide to add such a field in your system's "time.h" file),
 136 # add the name to a define such as

 138 # or
 139 #       -DTM_GMTOFF=_tm_gmtoff
 140 # to the end of the "CFLAGS=" line.
 141 # Neither tm_gmtoff nor _tm_gmtoff is described in X3J11's work;
 142 # in its work, use of "tm_gmtoff" is described as non-conforming.
 143 # Both Linux and BSD have done the equivalent of defining TM_GMTOFF in
 144 # their recent releases.
 145 #
 146 # If your system has a "zone abbreviation" field in its "struct tm"s
 147 # (or if you decide to add such a field in your system's "time.h" file),
 148 # add the name to a define such as
 149 #       -DTM_ZONE=tm_zone
 150 # or
 151 #       -DTM_ZONE=_tm_zone
 152 # to the end of the "CFLAGS=" line.
 153 # Neither tm_zone nor _tm_zone is described in X3J11's work;

 155 # Both UCB and Sun have done the equivalent of defining TM_ZONE in
 156 # their recent releases.
 157 #
 158 # If you want functions that were inspired by early versions of X3J11's work,
 159 # add
 160 #       -DSTD_INSPIRED
 161 # to the end of the "CFLAGS=" line.  This arranges for the functions
 162 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
 163 # "posix2time", and "time2posix" to be added to the time conversion library.
 164 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
 165 # time (rather than the time specified in the TZ environment variable)
 166 # to be used.
 167 # "offtime" is like "gmtime" except that it accepts a second (long) argument
 168 # that gives an offset to add to the time_t when converting it.
 169 # "timelocal" is equivalent to "mktime".
 170 # "timegm" is like "timelocal" except that it turns a struct tm into
 171 # a time_t using UTC (rather than local time as "timelocal" does).
 172 # "timeoff" is like "timegm" except that it accepts a second (long) argument
 173 # that gives an offset to use when converting to a time_t.
 174 # "posix2time" and "time2posix" are described in an included manual page.
 175 # X3J11's work does not describe any of these functions.
 176 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
 177 # These functions may well disappear in future releases of the time
 178 # conversion package.
 179 #
 180 # If you want Source Code Control System ID's left out of object modules, add
 181 #       -DNOID
 182 # to the end of the "CFLAGS=" line.
 183 #
 184 # If you'll never want to handle solar-time-based time zones, add
 185 #       -DNOSOLAR
 186 # to the end of the "CFLAGS=" line
 187 # (and comment out the "SDATA=" line below).
 188 # This reduces (slightly) the run-time data-space requirements of
 189 # the time conversion functions; it may reduce the acceptability of your system
 190 # to folks in oil- and cash-rich places.
 191 #
 192 # If you want to allocate state structures in localtime, add
 193 #       -DALL_STATE
 194 # to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
 195 #
 196 # If you want an "altzone" variable (a la System V Release 3.1), add
 197 #       -DALTZONE
 198 # to the end of the "CFLAGS=" line.
 199 # This variable is not described in X3J11's work.
 200 #
 201 # If you want a "gtime" function (a la MACH), add
 202 #       -DCMUCS
 203 # to the end of the "CFLAGS=" line
 204 # This function is not described in X3J11's work.

 210 # to the end of the "CFLAGS=" line.
 211 #
 212 # If you want strict compliance with XPG4 as of 1994-04-09, add

 214 # to the end of the "CFLAGS=" line.  This causes "strftime" to always return
 215 # 53 as a week number (rather than 52 or 53) for those days in January that
