System and method for identifying and correcting computer operations involving two digit year dates |
摘要 |
A system and method for identifying and correcting computer operations involving two digit year dates. The system includes: a computer and a routine for searching for a subtraction, comparison and sort operations on the computer involving a plurality of two digit quantities representing year dates. The subtraction operation is executed to obtain a difference value between the two quantities. A negative difference value is verified and a plurality of two digit numbers whose sum is 100 is added to the negative difference value so that the subtraction operation yields a correct result for two digit quantities representing years greater than or equal to the year 2000. A similar routine is added to existing computer code involving compare and/or sort operations.
