Daylight Saving Time Ends Sunday, November 1st

Annnnnd, we turn back time to gain an hour as Daylight Saving Time officially ends Sunday at 2AM. At least here in the United States. Except for Arizona. And last I knew, parts of Indiana. So, just let all the devices re-set themselves and move along with your day.

Why do we still observe? See what Wikipedia has to say about it.
