Abstract

A method of detecting year 2000 date problems in a computer system, and correcting some of those problems. One embodiment of the invention includes a computer system executing a program for testing and correcting, if possible, incorrect century values in a real time clock included in the computer system. This embodiment also includes a program for scanning files on the computer system and noting which files may have year 2000 type problems in the files.
