Thanks! I started working on this on Friday as well.

There is a test failure in TimeZoneEdgeCase.WET. I looks like WET was made an alias for Europe/Lisbon, almost as an arbitrary choice of replacement. But that removes the edge cases tested by TimeZoneEdgeCase.WET. I haven't looked to see if that means we are losing test coverage for the non-existent transitions tested by TimeZoneEdgeCase.WET, and if we need to replace them by other non-existent transitions for coverage.

Sigh. I don't know why the upstream stuff has to be so unstable. Oh well.

I don't think we're losing any coverage, and that the test could well be removed. But to err on the side of caution, I'll propose a test tweak instead.

Unfortunately, I am currently not in the position to build/test anything, so I could easily get things wrong. I guess we'll see if it turns green. But also given that inability, please feel free to ignore this PR altogether and move forward with your stuff. I was only hoping to make the CCTZ size of things easier, but until I can build/test again I may well be making it worse. :-(

I got so tired of Kokoro constantly breaking, and with the possibility of losing such a valuable contributor, I added GitHub Actions in 6624659. If you want to rebase onto or merge 6624659, I think the tests should just work for you. I'll delete the Kokoro tests shortly.

I'll open a new PR.
