ABSTRACT:
The invention provides a system and method for processing date-dependent information in two-digit format where the dates are in one or two centuries. The system according to the invention includes time change interfaces that convert date data from local time to zone time so that all of the dates are in one century. An application processes the date data in zone time instead of local time. The date data output from the application after processing is represented in zone time and therefore is converted by a time change interface from zone time to local time. According to the inventive method, the-two-digit years provided as inputs to the application are adjusted by either a time change value or a complement value. The time change value is the difference in years between local time and zone time. The complement value is the difference between one hundred years and the time change value. The output date data generated by the application is then similarly adjusted by either the time change value or the complement value so that the output dates are accurately represented in local time. Where the application has a master data file, the date data in the master data file is converted in advance to zone time.
