There is a timezone bug in Node 10.16.0. It is the same bug that I reported to Chromium here:
https://bugs.chromium.org/p/chromium/issues/detail?id=928068

Run the code in comment 1, from there, to reproduce the bug in Node 10.16.0.

I'm not sure if this is a V8 thing or if each environment has to fix the bug. If it is a V8 thing, perhaps this bug will go away by itself eventually. Otherwise, it needs to be addressed in Node.
