Daylight-saving time: Don't touch that clock in Arizona

The question stymies people across the country: Is it "spring forward, fall back" or the other way around?
The answer in Arizona is: "Who cares?"
On Sunday morning, as the rest of the continental United States prepared to set clocks back an hour, this state stayed, blissfully, on Mountain Standard Time. The exception is the Navajo Reservation, which does recognize the time change.
For most Arizonans, it means they'll be an hour ahead of California and two hours behind the East Coast.
In addition to Arizona, the change is not observed in Hawaii, American Samoa, Puerto Rico, Guam and the Virgin Islands.
A federal law specifies that daylight-saving time applies from 2 a.m. on the second Sunday of March until 2 a.m. on the first Sunday of November in areas that do not specifically exempt themselves.
Arizona observed daylight-saving time briefly during both World Wars and again in 1967, as required by the federal Uniform Time Act.
After 1967, the state opted to remain on standard time year-round.
