There is a part of Arizona and Nevada where even my Samsung Note 9 struggles to keep accurate time. Bullhead City (Arizona) and Laughlin (Nevada) operate in many respects, as one city, although they are each separate cities, each in in their own respective adjoining States. This dual-city is divided only by the Colorado River with several bridges connecting the two cities. The Laughlin Nevada half of this geography has daylight savings time for half of the year. The Bullhead City Arizona half never has daylight savings time. So you can gain or lose an hour (depending on the time of year), simply by crossing a city bridge. Scattered along the river that divides these two halves, are several cell phone towers on both sides of the river. The cell phone connection to the towers doesn’t seem to respect the city limits. One minute it’s 3:00 PM. A minute later, it’s 4:01 PM. Ten minutes after that, it’s 3:12 PM. You never really know what time it is because most of us don’t look at the time often enough to know for sure what time it really is in this situation. So before you leave home for either city, you set your phone to ignore the towers and just keep its own time. Then you make the one-hour time adjustment in your head, depending on which side of the river you’re on when you check your phone to see what time it is.
