[QUOTE=DrPatrickBarry;650373] Devices with issues included small devices (hand helds, etc) that contained internal clocks and were optimized as much as possible (due to power/memory constraints) and could not support a four digit year and very old devices, namely old Unix servers running COBOL/DB2 and other old languages. All of these retired COBOL programmers were rehired by the banks to update their ancient programs to support four digit years.

How come 1999 was not a four digit year?
