Re: Y2.1K Compliance

Hi Jim,

Of course, if they do that, anyone who's using cyymmdd to store dates may
have a problem at that time. If you have a date stored as 0290101 and the
window moves up, what does that date represent? Currently it would be
1929-01-01, but if the window moved, the year is below the window for the
20th century. Suddenly the data is invalid?
