Changes to future timestamps
Palestine now springs forward and falls back at 02:00 on the
first Saturday on or after March 24 and October 24, respectively.
This means 2022 falls back 10-29 at 02:00, not 10-28 at 01:00.
Changes to past timestamps
Simplify three Ukraine zones to one, since the post-1970
differences seem to have been imaginary. Move Europe/Uzhgorod and
Europe/Zaporozhye to 'backzone'; backward-compatibility links
still work, albeit with different timestamps before October 1991.
