> Hi all,
> Please review this backport to JDK13 updates:
> Bug: https://bugs.openjdk.java.net/browse/JDK-8212970
> Webrev: http://cr.openjdk.java.net/~rpatil/8212970/webrev.00/
> Original Changeset: https://hg.openjdk.java.net/jdk/jdk/rev/99d2dd7b84a8
> 
> The patch from jdk14 was not applied cleanly. Here is the change summary:
> 	- All the deletions in test/jdk/sun/util/calendar/zi/tzdata and
> test/jdk/sun/util/calendar/zi/tzdata_jdk are done manually.
> 	- The original patch(jdk14) had tzdata2019a vanguard format, but
> since the jdk13u is already patched with tzdata2019b rearguard format, in
> this patch tzdata files used are from tzdata2019b vanguard format.
> Post this backport, it will be easy to backport future tzdata versions starting
> tzdata2019c(JDK-8231098).
> 
> All the related tests including JCK are passed.
