From Inside Macintosh, Volume II, pg. 369:

"It's stored as a number of seconds since midnight, January 1, 1904, and
is updated every second."

Conversion routines are simple, just keep track of leap years and days
of the week.  If you need more, I'm sure somebody is waiting in the wings
with a suitable routine (although routines are in the Mac ROM to do it 
for Mac programmers).
