Now I understand your concern. I don't know if computers in AZ know that they are not supposed to change. Most computers in any time zone will change for DST. You have an excellent question.
The last few times I've purchased a computer, "Arizona time" was a separate choice when setting up the time zone. Before that (maybe 2008, maybe earlier--and I can't remember what operating systems I was using when) I would have to set it on MST and then uncheck the box for Daylight Savings Time. So people who didn't uncheck the box would have had their computer on the wrong time for part of the year.
