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

    172 # variables to be kept up-to-date by the time conversion functions.  Neither

    174 #
    175 # If your system has a "GMT offset" field in its "struct tm"s
    176 # (or if you decide to add such a field in your system's "time.h" file),
    177 # add the name to a define such as
    178 #	-DTM_GMTOFF=tm_gmtoff
    179 # to the end of the "CFLAGS=" line.  If not defined, the code attempts to
    180 # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
    181 # Similarly, if your system has a "zone abbreviation" field, define
    182 #	-DTM_ZONE=tm_zone
    183 # and define NO_TM_ZONE to suppress any guessing.  These two fields are not
    184 # required by POSIX, but are widely available on GNU/Linux and BSD systems.
    185 #
    186 # If you want functions that were inspired by early versions of X3J11's work,
    187 # add
    188 #	-DSTD_INSPIRED
    189 # to the end of the "CFLAGS=" line.  This arranges for the functions
    190 # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
    191 # "posix2time", and "time2posix" to be added to the time conversion library.
    192 # "tzsetwall" is like "tzset" except that it arranges for local wall clock
    193 # time (rather than the time specified in the TZ environment variable)
    194 # to be used.
    195 # "offtime" is like "gmtime" except that it accepts a second (long) argument
    196 # that gives an offset to add to the time_t when converting it.
    197 # "timelocal" is equivalent to "mktime".
    198 # "timegm" is like "timelocal" except that it turns a struct tm into
    199 # a time_t using UT (rather than local time as "timelocal" does).
    200 # "timeoff" is like "timegm" except that it accepts a second (long) argument
    201 # that gives an offset to use when converting to a time_t.
    202 # "posix2time" and "time2posix" are described in an included manual page.
    203 # X3J11's work does not describe any of these functions.
    204 # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
    205 # These functions may well disappear in future releases of the time
    206 # conversion package.
    207 #
    208 # If you don't want functions that were inspired by NetBSD, add
    209 #	-DNETBSD_INSPIRED=0
    210 # to the end of the "CFLAGS=" line.  Otherwise, the functions
    211 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
    212 # time library, and if STD_INSPIRED is also defined the functions
    213 # "posix2time_z" and "time2posix_z" are added as well.
    214 # The functions ending in "_z" (or "_rz") are like their unsuffixed
    215 # (or suffixed-by-"_r") counterparts, except with an extra first
    216 # argument of opaque type timezone_t that specifies the time zone.
    217 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
    218 #
    219 # If you want to allocate state structures in localtime, add
    220 #	-DALL_STATE
    221 # to the end of the "CFLAGS=" line.  Storage is obtained by calling malloc.
    222 #
    223 # If you want an "altzone" variable (a la System V Release 3.1), add
    224 #	-DALTZONE
    225 # to the end of the "CFLAGS=" line.
