Ah yes, the old bugaboo of keeping system time in some awful local time.
One of the things done right by Unix is to keep system time in GMT
(or CUT as it is now known to some degree in inaccuracy) and convert using
an adjustable bias when displaying it to humans.  System III's predicessor
started the useful hack of making this bias a per-user adjustable
quantity, so if I am on the East Coast using a West Coast computer,
"date" can give me "my local time".  So, by keeping system time in CUT,
you don't have to adjust the clock when you get off the plane - this
can cause havoc with things like Make - OOPS, don't have such tools
on the Mac :-)!!!  You just adjust the offset for the local bias from GMT.
