  • Year 2000 compliance method which overlays day and/or month fields with century data to expand single century systems to handle multiple century data
    Patent number: 6092073
    Abstract: A new method of numeric data handling employing numeric data overlay. This method is applied to the year 2000 problem such that it allows the storage of multiple century information along with the month, day and year into the 6-digit date field. The integrity of the existing data in the field is maintained along with the additional century information. This is accomplished by algorithms for encoding and decoding the date information consistent with the method of numeric data overlay. This method takes advantage of the unused number sequences above 12 in the month field and above 31 in the day field. Combining the power of the two ranges, a total of 24 range combinations are possible which can thus code for 24 different centuries while maintaining the original year, month and day information in the original 6-digit field format.
