Only a couple of responses, but thus far it seems to fit.

I had two responses that this occured to others during Y2K testing.
Clock forward, clock back, and this can happen.

Well, I was skeptical because of the nature of this machine, but I
checked and sure enough, there's some Jan 1 dates in the log files. So
much for anyone telling me about testing on this box!! :-)

Thanks for the help!
