I made a very specific request to put 01:00 back in the main file for
15 months. A timeframe that would allow fixed/updated tools to be
rolled out. Had my request and advice been followed, these developers
and many others would not be frustrated today.

FWIW, I've done my part - there are new releases of both time-zone
parsers that I directly control (Joda-Time and ThreeTen-Backport), and
I have argued for changes to the JDK. But changes to the JDK or
TZUpdater will not be quick.

I say again, the right course of action is to revert the change and
use 01:00 in the main file until the JDK teams have had a chance to
fix their tools.
