This doesn't work at all if you want to properly display times in the past.

If you are in the new PST, then the setting is PST, and the timezone file
properly has the current state as ending in November 2023 and the new state
taking effect in November 2023 and you get proper display of time before
and after the change.

If you are in the new PST and set your timezone to MST then all times
before November 2023 are displayed incorrectly.
