            tz-art.html tz-link.html

Log Message:
Import tzcode 2023d:

    localtime.c no longer mishandles TZif files that contain a single
    transition into a DST regime.  Previously, it incorrectly assumed
    DST was in effect before the transition too.  (Thanks to Alois
    Treindl for debugging help.)

    localtime.c's timeoff no longer collides with OpenBSD 7.4.

    The C code now uses _Generic only if __STDC_VERSION__ says the
    compiler is C11 or later.

    tzselect now optionally reads zonenow.tab, to simplify when
    configuring only for timestamps dated from now on.

    tzselect no longer creates temporary files.

    tzselect no longer mishandles the following:

      Spaces and most other special characters in BUGEMAIL, PACKAGE,
      TZDIR, and VERSION.

      TZ strings when using mawk 1.4.3, which mishandles regular
      expressions of the form /X{2,}/.

      ISO 6709 coordinates when using an awk that lacks the GNU
      extension of newlines in -v option-arguments.

      Non UTF-8 locales when using an iconv command that lacks the GNU
      //TRANSLIT extension.

    zic no longer mishandles data for Palestine after the year 2075.
    Previously, it incorrectly omitted post-2075 transitions that are
    predicted for just before and just after Ramadan.  (Thanks to Ken
    Murchison for debugging help.)

    zic now works again on Linux 2.6.16 and 2.6.17 (2006).
