I finally figured out the time situation in Arizona. My confusion was in thinking Arizona was Pacific time for some reason, but it's in Mountain time. So when Daylight Savings kicks in and Pacific time jumps forward an hour, it becomes what Mountain time was, which is what Arizona remains. When Daylight Savings ends, California goes back to Pacific Standard, and Mountain states all change back to what Arizona stayed on. Basically, during Daylight Savings, Arizona is the same as Pacific time zone states. Otherwise it's a Mountain time zone state. Got it!
