US Army Year 2000 (Y2K) Action Plan Revision II.

Abstract

The Year 2000 (Y2K) problem stems from the use of two-digit year fields instead of four digit year fields in software, hardware, and firmware, including embedded chips. This will cause many computer programs and devices to fail as they attempt to calculate against the year "00,' not recognizing that the year is actually 2000. The resulting inaccuracies in date- related calculations will generate corrupt data results and will cause some systems to fail entirely. If erroneous information goes unrecognized, the problem is perpetuated through interfaces with other systems. While this is the basis of the problem, it is actually more complex. Many systems and devices with embedded information technology (IT) have faulty date logic that does not recognize that the Y2K is a leap year. Some systems use the code "00 or 99" as a trigger to execute an action, while others, such as the Global Positioning System (UPS), have overflow or rollover problems.
