Hey, we get plenty of daylight as it is here, no need for us to "save" any, but if y'all wanna go changing all your clocks back'n'forth twice a year, that's up to you... ;^)
BTW, most timezone selectors should offer a specific "Arizona" timezone, so look for that setting first; if you don't find that, then you can set things to MST or GMT -7 and if possible disable Daylight Saving.
