(tz) Upgrade time-zone data to tzdata2020e

    XMLWordPrintable

    Details

      Description

      The 2020e release of the tz code and data is available. It reflects the
      following changes, which were either circulated on the tz mailing list or
      are relatively minor technical or administrative changes:

         Briefly:
           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.
