ABSTRACT:
According to the present invention, an apparatus and method for processing date fields in computer systems without the negative implications of the turn of the century problem is disclosed. The proposed solution is known as the "system encapsulation" method. In a preferred embodiment of the present invention, the code for the application software running on the computer system is not modified in any way. Instead, the preferred methods of the present invention modify the date-dependent information in the computer system database files and resets the system clock by adding or subtracting a certain number of "offset" years from the dates being processed by the system (for example, 28 years). The two-digit date representations in the modified database contain both positive and negative two-digit date representations, allowing the processing of data that spans 199 years and covers portions of three different centuries. This approach allows the application software to process the date-dependent data normally.
