I always thought it was a hoot to fly from Phoenix to Las Vegas in the summer because you “arrive in Vegas before you left Phoenix” thanks to the fact that AZ does not ever go on DLST and the flight is less than an hour!

That would mean you really went through a time-warp as AZ and Vegas have the same time during summer months! You scenario only works during the winter.

(And your scenario displays completely what the problems would be if a bunch of other states decided to either not have DST or have year-round DST. Confusion would abound.)

In the summer, Phoenix and Las Vegas are on the same time. Since AZ doesn't observe DST, when the clock moves forward for the Pacific Time Zone, it catches AZ at MST. Both are UTC -7 hours right now. It's the winter where AZ is an hour ahead, thus the arriving before leaving can occur.
