- Problem here: on most unix systems the parent only gets the lower eight
- bits of the exit value. This would mean max/min values of 127/-128.
- Not very practical if the value is supposed to be in minutes.
- Fine if the return value is in hours, though, but then you're still
- leaving parts of the world out. Besides, we've pretty much decided that
- we should at least have precision in minutes.
-
- Of course, we could make the precision HALF-hours. This is kind of silly,
- but is there anywhere in the world whose time is not an integral number of
- half hours away from GMT?

- By the way, I definitely feel that we need both a per-system time zone
- and a per-process (or per-user) time zone. Machines are stationary,
- but users are mobile (and sometimes far away).
-
- (I imagine that timezone is not in the dictionary because its not a word).
