Uh, no. they wouldn’t.

MST with DST off == PDT year round.

Simple. No semi-annual change required.

If you don’t want to lie to the computer, then all one needs to do is rename the corresponding
timezone files…

MST becomes the new PST file, etc.

Of course at some point, the timezone files went weird and started getting named after cities instead of timezones, so
the renaming is a little less intuitive, but it’s still doable.
