    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 UTC (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.

    198 # conversion package.

    204 # This reduces (slightly) the run-time data-space requirements of

    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.
