I would note that postal codes and countries are themselves shapes which could be in more than one time zone. I don't think there are any multi-zone cities, fortunately. However, getting this data and keeping it up to date seems like a very difficult proposition. -dave /*========================== VegGuide.Org Your guide to all that's veg ==========================*/
