So, basically the problem is on windows the mappings from UTC actually sets it to GMT timezone. for example:
"Mon Jan 06 2020 00:00:00 GMT+0000 (Greenwich Mean Time)"
Instead it should be this:
"Mon Jan 06 2020 00:00:00 GMT+0000 (Coordinated Universal Time)"
As it is on macbooks.

As Jon pointed out, the CLDR mapping is not there for "Etc/UTC". Instead, the CLDR maps the Windows "UTC" time zone to "Etc/GMT". IMHO - this is in error.

Basically instead of mapping to GMT it should go to UTC to provide a consistent experience with macs and ubuntu otherwise we have out of sync times between OS.
