[ANNOUNCEMENT] Updated: tzcode, tzdata 2020f

[Brian Inglis]

The following packages have been upgraded in the Cygwin distribution:

* tzcode	2020f
* tzdata	2020f

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.

  2020e bug. (Problem reported by Deborah Goldsmith.)
