Time zone in Arizona
Arizona keeps Mountain Standard Time (MST, UTC−7) all year, with one exception: the Navajo Nation in the northeast of the state observes daylight saving time, as NIST notes, so in summer its clocks are an hour ahead of the rest of Arizona.
Phoenix lies at 112.1° west, where mean solar time is UTC−7:28 (four minutes per degree of longitude). The clocks run 28 min ahead of the sun, so on average the sun is highest at about 12:28 PM.
Daylight saving time in Arizona
No. Arizona has not used daylight saving time since 1967 (it did between 1918 and 1967, according to tzdata’s historical records), and the clocks stay on MST (UTC−7) all year.
Federal law (15 U.S.C. §260a) lets a state exempt itself from daylight saving time; places that do so stay on standard time all year. Hawaii, American Samoa, Guam, Puerto Rico, the US Virgin Islands and most of Arizona do not observe it.
Clock history of Arizona
Arizona has kept the same clocks as Phoenix since at least 1970: tzdata records both under America/Phoenix. There has been no daylight saving time since 1970; the last summer clock change in the record was in 1967. Before 1970 local practice could differ from Phoenix’s, and tzdata does not track it separately; the year-by-year table, which starts with Phoenix’s local mean time, is on the America/Phoenix page.
