When Yukon did that, we modeled that as America/Whitehorse and
America/Dawson being on -07 standard time all year, with the
abbreviation "MST". This made sense, as that's what "MST" means
elsewhere in North America.
This new change, if it becomes law, won't be so easy to deal with. It
will likely cause "Pacific Time" to be synonymous with -07 and "Mountain
Time" to be synonymous with -06 in popular usage, which means that the
entries for America/Whitehorse and America/Dawson will need to change
from "MST" to something else, as "MST" will be misleading.
Yes. Under option #4 (from the options I presented in another email thread), the following zones would all need to be reconfigured to use UTC-07 and the "PST" abbreviation year-round:
•America/Los_Angeles
•America/Phoenix
•America/Vancouver
•America/Creston
•America/Dawson_Creek
•America/Fort_Nelson
•America/Whitehorse
•America/Dawson
•America/Hermosillo
•PST
One west coast zone that could be problematic is America/Tijuana. If it follows the US and moves to permanent UTC-07, then it can simply be added to the list above. Otherwise, under option #4, it has to start using AKST/AKDT which is admittedly not what anybody will wish for.
And then there is "PST8PDT". This one might need to be abandoned no matter what path we take.
