Arizona is in the Mountain time zone and does not observe Daylight Savings Time. I will try to find out way. Click below to see current time and temperatures. We are having a delightful Spring but expect it to get warmer soon. http://www.timeanddate.com/worldclock/city.html?n=197
Last year (2012) I turned on my air conditioner about May 1. So far this year (5/10/13) I have not turned it on. It has actually felt cool, and I keep my front door open in the early evening. I will probably need the AC by the end of next week when it is expected to be 100!
