Yeah, it gets complicated, since the State of Arizona ignores
Daylight Saving Time adjustments.  On the other hand, most of
Arizona is covered by the Navajo Nation, which *does* observe DST.
Except for some government offices on the reservation.  And the Hopi
Nation goes along with the local state rules, so pay attention.  :-/

So, yeah, Navajo is always the same as most of US/Mountain, but the
parts in Arizona don't ignore DST like the rest of the state does.
