Thanks for the heads-up. This announcement is unclear, as it could mean
that the transition is:
(A) from Thursday 10-28 24:00 to Thursday 10-28 23:00.
And it could also mean that the transition is:
(B) from Friday 10-29 01:00 to Friday 10-29 00:00.
For Palestine's transition to winter time, tzdb currently uses method
(A) for 2014 and 2019, and method (B) for 2015-2018 and for 2020-2021.
Do you know which is the correct method for the year 2021? If method (B)
is correct, tzdb is already OK; if not, we'll need to update tzdb.
Surely it would be better for everyone concerned if Palestine were
consistent about using method (A) or method (B). I worry that the actual
transition rule has not been specified clearly and that tzdb has been
interpreting ambiguously-specified rules somewhat at random.
Thank you for any info you can provide to clear this up.
