TZ: 2020d - Closed
Description
The 2020d release of the tz code and data is available. It reflects the 
following changes, which were either circulated on the tz mailing list or are 
relatively minor technical or administrative changes:

   Briefly:
     Palestine ends DST earlier than predicted, on 2020-10-24.

   Changes to past and future timestamps

     Palestine ends DST on 2020-10-24 at 01:00, instead of 2020-10-31
     as previously predicted (thanks to Sharef Mustafa.)  Its
     2019-10-26 fall-back was at 00:00, not 01:00 (thanks to Steffen
     Thorsen.)  Its 2015-10-23 transition was at 01:00 not 00:00, and
     its spring 2020 transition was on March 28 at 00:00, not March 27
     (thanks to Pierre Cashon.)  This affects Asia/Gaza and
     Asia/Hebron.  Assume future spring and fall transitions will be on
     the Saturday preceding the last Sunday of March and October,
     respectively.
