A date rollover bug that occurs due to using two digits for the year. The assumption was that no one had to worry about the first two digits, which were assumed to be "19." Unfortunately, when the year 2000 rolled around, all that software thought it was 1900, because of that assumption. Oops. FLEX date storage suffers from this problem. So welcome to the 20th century. Again. :)
