I work with a database that has its origins in the COBOL era. All of the date fields are specified in the copybooks as four PIC 99 (i.e. two decimal digits) subfields, CCYYMMDD. This separation of CC and YY surprised me until I realized that it allowed them to add Y2K support by setting the default for CC to '19' and switching it later. |
