The following packages have been upgraded in the Cygwin distribution:

* tzcode	2021c
* tzdata	2021c

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 2021c - 2021-10-01 14:21:49 -0700

* Briefly:

    Revert most 2021b changes to 'backward'.
    Fix 'zic -b fat' bug in pre-1970 32-bit data.
    Fix two Link line typos.
    Distribute SECURITY file.

    This release is intended as a bugfix release, to fix compatibility
    problems and typos reported since 2021b was released.

* Changes to Link directives

    Revert almost all of 2021b's changes to the 'backward' file,
    by moving Link directives back to where they were in 2021a.
    Although 'zic' doesn't care which source file contains a Link
    directive, some downstream uses ran into trouble with the move.
    (Problem reported by Stephen Colebourne for Joda-Time.)

    Fix typo that linked Atlantic/Jan_Mayen to the wrong location
    (problem reported by Chris Walton).

    Fix 'backzone' typo that linked America/Virgin to the wrong
    location (problem reported by Michael Deckers).

* Changes to code

    Fix a bug in 'zic -b fat' that caused old timestamps to be
    mishandled in 32-bit-only readers (problem reported by Daniel
    Fischer).
