Some software blows up on dates at other times.  I'm aware of some old
DEC software (don't worry... you're NOT using it... it's single user!)
that keeps the date year as a 5 bit offset from 1972.  Let's see...
1972+31=2003, so it blows up in 2004.  Probably, tho, the display-a-year
routine isn't written to handle beyond 31-dec-99, since no one expects
that RT11 (oops, now I said it) will still be used then.  I hope.
