Only sorta related but that map doesn’t show this interesting detail which I experienced first hand: The Navajo Nation Reservation is on a different time zone than the state it is mostly inside. But the Hopi Reservation is entirely contained within the Navajo, and is on a different time zone. When we drove through that region my phone just freaked out, switching times back and forth arbitrarily. And the hotel had three clocks in the lobby for clarification.
