Date arithmetic, compares, and sorting Verify that the software correctly calculates the duration between two dates, can correctly determine a date plus or minus an offset and can convert dates to their Julian equivalent. Dates that are compared to other dates for logic branching must also continue to function correctly. Software must also continue to correctly sort or merge on date fields where applicable. Scheduling Verify that scheduling functions and software continue to recognize specified patterns or explicit dates, elapsed times, can operate during the rollover from 1999 to 2000. Special value dates Verify software that uses date fields as special values, continues to operate correctly and does not conflict with actual dates.
Special values can include such things as 'catalog control' or 'non-expiring'.
For each product a description of testing criteria and results will be documented including any problems and resolutions during testing. The product documentation will also include the software level and version and the person responsible for testing the product. Time Customers will be allocated a block of time that will be negotiated with each customer for exclusive use of the test system. Due to requirement difference of each customer it is expected that the allocated time for each customer be from a few days to several weeks, over a period of several months. The GGDC will assist customers as needed for Y2K systems, this includes moving of data between the production system and the Y2K test system, restarting the system with a new date, tape mounts, output handling and other situations when appropriate.
