Maybe I can help you with that. I’m from Arizona, which does not observe any time change, effectively meaning that we’re on MST for part of the year and PDT for the rest. I have _never_ heard of someone living in Arizona refer to our time zone as MST, MDT, PST, or PDT, but only as “Arizona time” or something to that effect.
