This arrange for "timezone" and "daylight" # variables to be kept up-to-date by the time conversion functions. Neither # "timezone" nor "daylight" is described in X3J11's work. # # If your system has a "GMT offset" field in its "struct tm"s # (or if you decide to add such a field in your system's "time.h" file), # add the name to a define such as # -DTM_GMTOFF=tm_gmtoff # to the end of the "CFLAGS=" line. If not defined, the code attempts to # guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this. # Similarly, if your system has a "zone abbreviation" field, define # -DTM_ZONE=tm_zone # and define NO_TM_ZONE to suppress any guessing. These two fields are not # required by POSIX, but are widely available on GNU/Linux and BSD systems. # # If you want functions that were inspired by early versions of X3J11's work, # add # -DSTD_INSPIRED # to the end of the "CFLAGS=" line. 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 don't want functions that were inspired by NetBSD, add # -DNETBSD_INSPIRED=0 # to the end of the "CFLAGS=" line. Otherwise, the functions # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the # time library, and if STD_INSPIRED is also defined the functions # "posix2time_z" and "time2posix_z" are added as well. # The functions ending in "_z" (or "_rz") are like their unsuffixed # (or suffixed-by-"_r") counterparts, except with an extra first # argument of opaque type timezone_t that specifies the time zone. # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. # # 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. # # 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. If you want to pass PCTS, add # -DPCTS # to the end of the "CFLAGS=" line. # # If you want strict compliance with XPG4 as of 1994-04-09, add # -DXPG4_1994_04_09 # to the end of the "CFLAGS=" line. 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.
