Abstract
The year 2000 Problem is addressed by hard coding a Date Translation Object which finds and reduces the two digit year dates by a constant factor of 28 years. After data processing is complete, the Date Reduction Object reintroduces the constant factor into the data values.
Claims3
A method of operating a data processing system having:
- data processing means for processing data including two-digit year values;
- data input means for receiving data from an external source;
- and
- data output means for delivering data to an external recipient, said method comprising:
- selecting a year reduction value that is a non-zero integral multiple of 28;
- delivering individual two-digit year values from the external source to the data input means
- converting each two digit year value received by the data input means to a reduced year value by subtracting the year reduction value from each said year value received by the data input means;
- delivering the reduced year values directly from the data input means to the data processing means:
- processing data including the reduced year values;
- delivering processed data including reduced year values directly from the data processing means to the data output means;
- adding the year reduction value to each year value delivered by the data output means to an external recipient.

In a data processing system comprising;
- data processing means for processing data including two-digit year values;
- data input means for transmitting data from an external source to the data processing means;
- data output means for delivering data from the data processing means to an external recipient;
- an input date translation object associated with the data input means for converting to a reduced year value each two digit year value transmitted by the data input means from the external source to the data processing means by subtracting a selected year reduction value from each said year value as the year value is transmitted;
- and
- an output date translation object associated with the data output means for converting each reduced vear value each two digit vear value delivered by the data input means from the data processing means to the external recipient by adding the selected year reduction value to each said year value as the year value is delivered to the external recipient.
