Willie,

   Yes, this has happened to me also.

   Note that 2^32 hundredths-of-a-second = 497.1027 days,
   which seems like a plausible explanation of what happened.

   It's also the case that the CPU time of a process rolls over
   after the same period of time (497+ days).  Yes, this has happened
   to me.  Really.

   Hah! -- whoever designed such short time limits?
   O they of little faith!

Cheers, Joseph
