The following packages have been upgraded in the Cygwin distribution:

* tzcode	2023b
* tzdata	2023b

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 summer
daylight saving time rules, UTC offsets, and time zone boundaries.
The tzcode package provides the tzselect, zdump, and zic utilities.

Release 2023b	2023-03-24


* Lebanon delays the start of DST this year.

Changes to future timestamps

* This year Lebanon springs forward April 20/21 not March 25/26.
  The 2023b release of the tz code and data is available. It follows so
  closely on the 2023a release because Lebanon's government announced
  that Lebanon's spring-forward transition previously scheduled for the
  end of this week has been delayed until April 20.
