The international date line has been there forever! Also, time is always measured wrt Greenwich time in England. So, not a big deal. As Simon above said, it is probably just a test case that fell through the cracks! Go to http://wwp.greenwichmeantime.com/info/timezone.htm for more info on Time Zones. p.s. "or something like that" has very little meaning! :-)
