Indeed.  Some clever person might decide to power of two which was a multiple 
of 8 or 16 or so, so that you don't even have to shift bits, and you end up 
with something that resembles (struct timeval).  An integral timer with a 
resolution of 1 tick = 1 second has a lot going right for it.

And of course, there is the issue of choosing yet another epoch that nobody 
else has heard of.  If you talk to an astronomer, they really want to 
standardarize on J2000.
