Test on a Mac to be sure what happens there.  The native epoch there is 
Jan 1,  1904.  (Ignoring Mac OS X.)  So time is currently negative (when 
viewed as signed 32 bits, and the end of time is in 2040).  

(The modern Mac OS (from 1990 or so onwards) supplies 64-bit signed 
time, same epoch, and I believe "Carbon" removes the old 32-bit time.)
