Datetime math is inherently so. So one wonders why the whole world doesn't migrate to a single timezone. There would be no more confusion between EST, CEST, GMT, +1100, etc. The trade off, of course, would be that now you'd have to know the "daylight" hours of a particular part of the world or business with whom you wanted to interact, but the math sure would be easier all-round.
