Does anyone know the geographical boundary between America/Ciudad_Juarez and America/Ojinaga? Is there some geographical feature like a river that demarcates the boundary between them? The law didn’t say anything about that; it just lists municipalities. Do these municipalities abut each other so we can use those boundaries?
Unfortunately, some of the specifically listed municipalities are actually quite distant from one another.
"Assuming an extension of the Texas' time zone boundary between Hudspeth and Presidio Counties, that would put such a dividing line near Lomas de Arena in Chihuahua."
I'd imagine that's at least close enough to the intent here to suffice until it more clearly emerges what folks are actually observing locally.
