Each decade there will be some Y2K bug reruns popup, if left undetected.
The standard solution for clients that refused to redo the db to 
4-column dates was to add an if into the code, for example:
if date < 39, use 2000 + date else use 1900 + date
in the repeated assumption that surely by XX they will have upgraded 
this system?!?!?
39 through 69 were common dates, but generally on the '9' year.
So each decade, rollover will see some systems fail.
Cascading failure while avoiding a fix to the real problem, eh?
