No wonder we were confused. Today I googled a bit and found this tidbit on: http://www.usatoday.com/story/news/nation-now/2017/03/09/arizona-no-daylight-saving-time/98964644/ http://www.usatoday.com/story/news/nation-now/2017/03/09/ari... «The Navajo Reservation observes daylight saving time; the Hopi Reservation does not.
