Import tzdata2019a from ftp://ftp.iana.org/tz/releases/tzdata2019a.tar.gz
Release 20198 - 2019-03-25 22:01:33 -0700
Briefly:
Palestine summer time starts on 2019-03-30 instead of 2019-03-23.
Metlakatla switched back to rejoin Alaska Time on 2019-01-20 at 02:00.
Israel observed summer time in 1980 (08-02/09-13) and 1984 (05-05/08-25).
Etc/UCT is now a backward-compatibility link to Etc/UTC, instead
of being a separate zone that generates the abbreviation "UCT".

News for the tz database
+Release 20198 - 2019-03-25 22:01:33 -0700
+
+ Briefly:
+ Palestine "springs forward" on 2019-03-30 instead of 2019-03-23.
+ Metlakatla "fell back" to rejoin Alaska Time on 2019-01-20 at 02:00.
+
+ Changes to past and future timestamps
+
+ Palestine will not start DST until 2019-03-30, instead of 2019-03-23 as
+ previously predicted. Adjust our prediction by guessing that spring
+ transitions will be between 24 and 30 March, which matches recent practice
+ since 2016. (Thanks to Even Scharning and Tim Parenti.)
+
+ Metlakatla ended its observance of Pacific standard time,
+ rejoining Alaska Time, on 2019-01-20 at 02:00. (Thanks to Ryan
+ Stanley and Tim Parenti.)
+
+ Changes to past timestamps
+
+ Israel observed DST in 1980 (08-02/09-13) and 1984 (05-05/08-25).
+ (Thanks to Alois Treindl and Isaac Starkman.)
+
+ Changes to time zone abbreviations
+
+ Etc/UCT is now a backward-compatibility link to Etc/UTC, instead
+ of being a separate zone that generates the abbreviation "UCT",
+ which nowadays is typically a typo. (Problem reported by Isiah
+ Meadows.)
+
+ Changes to code
+
+ zic now has an -r option to limit the time range of output data.
+ For example, 'zic -r @1000000000' limits the output data to
+ timestamps starting 1000000000 seconds after the Epoch.
+ This helps shrink output size and can be useful for applications
+ not needing the full timestamp history, such as TZDIST truncation;
+ see Internet RFC 8536 section 5.1. (Inspired by a feature request
+ from Christopher Wong, helped along by bug reports from Wong and
+ from Tim Parenti.)
+
+ Changes to documentation
+
+ Mention Internet RFC 8536 (February 2019), which documents TZif.
+
+ tz-link.html now cites tzdata-meta
+ <https://tzdata-meta.timtimeonline.com/>.
