So they might just be ignoring the Navajo nation's rules and using their neighbor's rules instead; I think that's done elsewhere as well, near time zone boundaries (I think there may be cases where a location that's far from other places in its own time zone, but close to a location in another time zone, sets its clocks as if they were in the other time zone).
