christos f9589d4feb Release 2015g - 2015-10-01 00:39:51 -0700 
Changes affecting code

    localtime no longer mishandles America/Anchorage after 2037.
    (Thanks to Bradley White for reporting the bug.)

    The localtime module allows the variables 'timezone', 'daylight',
    and 'altzone' to be in common storage shared with other modules,
    and declares them in case the system <time.h> does not.
    (Problems reported by Kees Dekker.)

    On platforms with tm_zone, strftime.c now assumes it is not NULL.
    This simplifies the code and is consistent with zdump.c.
    (Problem reported by Christos Zoulas.)

  Changes affecting documentation

   The tzfile man page now documents that transition times denote the
   starts (not the ends) of the corresponding time periods.
   (Ambiguity reported by Bill Seymour.)

# -DTZ_DOMAIN=\"foo\" to use "foo" for gettext domain name; default is "tz"
# -DTZ_DOMAINDIR=\"/path\" to use "/path" for gettext directory;

# If you want to use System V compatibility code, add
# -DUSG_COMPAT
# to the end of the "CFLAGS=" line. 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.
