[ Impact ]

 Recently the Egyptian authorities decided to restore DST. The first switch after the change is expected to take place on last Friday of April. The upstream tzdata 2023a release already reflects this change.

[ Test Plan ]

 * Set system timezone to Egypt (e.g. Africa/Cairo).
 * Set system time to 2023-04-27 23:59.
 * Wait and observe what happens at 2023-04-28 0:00

[ Where problems could occur ]

 * Systems with incorrect timezone set (e.g. located outside of Egypt but still using Egyptian time) may observe unexpected time shift.
