[ANNOUNCEMENT] Updated: tzcode, tzdata 2021d

[Cygwin tzcode/tzdata Maintainer]

The following packages have been upgraded in the Cygwin distribution:

* tzcode	2021d
* tzdata	2021d

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.
The tzcode package provides the tzselect, zdump, and zic utilities.

For more details on changes, please see the announcement or below:

Release 2021d - 2021-10-15 13:48:18 -0700

  Briefly:
    Fiji suspends DST for the 2021/2022 season.
    'zic -r' marks unspecified timestamps with "-00".

  Changes to future timestamps

    Fiji will suspend observance of DST for the 2021/2022 season.
    Assume for now that it will return next year.  (Thanks to Jashneel
    Kumar and P Chan.)

  Changes to code

    'zic -r' now uses "-00" time zone abbreviations for intervals
    with UT offsets that are unspecified due to -r truncation.
    This implements a change in draft Internet RFC 8536bis.
