Subject: [PATCH] Fix Palestine 2015 fall and 2020 spring
* NEWS: Mention this.
* asia (Palestine): Correct transitions for 2015-10-23 (at 01:00,
not 00:00) and spring 2020 (on March 28, not March 27). Thanks to
Pierre Cashon. Alter future spring transitions accordingly; these
are guesswork anyway, so make them more consistent with fall.
Clean up some of the past "only" lines, since really just the
dates are known.
