Our customer is a major airline in Mexico and they tell me the time
should America/Ojinaga should be the same as America/Denver.

Estado de Chihuahua, acorde a sus correlativos a su franja fronteriza,
se aplica el meridiano 105 grados al oeste de Greenwich."

And then it says "el meridiano 105 grados al oeste de Greenwich" giving
the degrees from Greenwich.
