  In rare cases; otherwise, business day convention, right along with a ton of other conventions make local timezones a total win. Going with one time for everyone would require a lot more information. I work across zones and continents a lot. This is not hard. Besides, moot point. One time stamp will never fly politically. I will not support an effort to attempt it either.
