Interesting Fact - Daylight Saving Time

In the US Arizona does not observe daylight saving time.

(Temperatures in and around Phoenix and Tucson are hotter than any other large U.S. metropolitan area during the summer, resulting in more power usage from air conditioning units and evaporative coolers in homes and businesses. An extra hour of sunlight while people are active would cause people to run their cooling systems longer, thereby using more energy (however, the large Navajo Indian Reservation, which extends from Arizona into two adjacent states, does). It must be very confusing.)
