This arranges for the functions # "tzsetwall", "offtime", "timelocal", "timegm", "timeoff", # "posix2time", and "time2posix" to be added to the time conversion library. # "tzsetwall" is like "tzset" except that it arranges for local wall clock # time (rather than the time specified in the TZ environment variable) # to be used. # "offtime" is like "gmtime" except that it accepts a second (long) argument # that gives an offset to add to the time_t when converting it. # "timelocal" is equivalent to "mktime". # "timegm" is like "timelocal" except that it turns a struct tm into # a time_t using UT (rather than local time as "timelocal" does). # "timeoff" is like "timegm" except that it accepts a second (long) argument # that gives an offset to use when converting to a time_t. # "posix2time" and "time2posix" are described in an included manual page. # X3J11's work does not describe any of these functions. # Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0. # These functions may well disappear in future releases of the time # conversion package. # # If you want to allocate state structures in localtime, add # -DALL_STATE # to the end of the "CFLAGS=" line. Storage is obtained by calling malloc. # # If you want an "altzone" variable (a la System V Release 3.1), add # -DALTZONE # to the end of the "CFLAGS=" line. # This variable is not described in X3J11's work. # # If you want a "gtime" function (a la MACH), add # -DCMUCS # to the end of the "CFLAGS=" line # This function is not described in X3J11's work. # # NIST-PCTS:151-2, Version 1.4, (1993-12-03) is a test suite put # out by the National Institute of Standards and Technology # which claims to test C and Posix conformance.

This causes "strftime" to always return # 53 as a week number (rather than 52 or 53) for those days in January that # before the first Monday in January when a "%V" format is used and January 1 # falls on a Friday, Saturday, or Sunday.
