Navajo Nation is (in part anyway) contained within Arizona, but it keeps time different from the rest of Arizona. Hopi nation follows Arizona rules
America/Phoenix does not mean "Arizona", just as America/Toronto does not mean "Ontario" and America/Denver does not mean "Colorado". These names stand for regions of clocks that have agreed since 1970, for which Phoenix, Toronto, and Denver are the main locations. The names do not stand for their containing politial regions; this has always been true and I'm not proposing to change this. For time stamps after 1970, the Navajo reservation follows the same rules as America/Denver, just as the Hopi reservation follows the same rules as America/Phoenix. It is inconsistent to give the Navajo reservation its own zone while not extending the same privileges to the Hopi. And a similar argument applies to the Osage, Yakama, Flathead, Wind River, and Rosebud reservations. There are hundreds more.
