I'm sure its not a drived requirement. 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! :-)
