The following packages have been uploaded to the Cygwin distribution:

* tzdata	2020e

The Time Zone Database (often called tz, tzdb, or zoneinfo) contains
data that represents the history of local time for many locations around
the world, and supports conversion of UTC time to local time at those
locations to allow display of those local times. It is updated
periodically to reflect changes made by political bodies to daylight
saving (summer time) rules, UTC offsets, and time zone boundaries.

Release 2020e - 2020-12-22 15:14:34 -0800

    Volgograd switches to Moscow time on 2020-12-27 at 02:00.

  Changes to future timestamps

    Volgograd changes time zone from +04 to +03 on 2020-12-27 at 02:00.
    (Thanks to Alexander Krivenyshev and Stepan Golosunov.)

  Changes to past timestamps

    Correct many pre-1986 transitions, fixing entries originally
    derived from Shanks.  The fixes include:
      - Australia: several 1917 through 1971 transitions
      - Bahamas: several 1941 through 1945 transitions
      - Bermuda: several 1917 through 1956 transitions
      - Belize: several 1942 through 1968 transitions
      - Ghana: several 1915 through 1956 transitions
      - Israel and Palestine: several 1940 through 1985 transitions
      - Kenya and adjacent: several 1908 through 1960 transitions
      - Nigeria and adjacent: correcting LMT in Lagos, and several 1905
        through 1919 transitions
      - Seychelles: the introduction of standard time in 1907, not 1906
      - Vanuatu: DST in 1973-1974, and a corrected 1984 transition
    (Thanks to P Chan.)

    Because of the Australia change, Australia/Currie (King Island) is
    no longer needed, as it is identical to Australia/Hobart for all
    timestamps since 1970 and was therefore created by mistake.
    Australia/Currie has been moved to the 'backward' file and its
    corrected data moved to the 'backzone' file.

  Changes to past time zone abbreviations and DST flags

    To better match legislation in Turks and Caicos, the 2015 shift to
    year-round observance of -04 is now modeled as AST throughout before
    returning to Eastern Time with US DST in 2018, rather than as
    maintaining EDT until 2015-11-01.  (Thanks to P Chan.)

  Changes to documentation

    The zic man page now documents zic's coalescing of transitions
    when a zone falls back just before DST springs forward.
