How the product handles dates:
MS-DOS recognizes dates beyond the year 2000. It does not display the full year, but will sort files correctly.
Two-digit shortcut handling:
If a 2-digit date is entered, the operating system will assume that the date entered is in the 1900s.
The MS-DOS╥ DATE command does not correctly handle 2-digit dates from 00û79. This command returns the error message "Invalid Date" upon entry of 2-digit dates within this range. Dates entered using a 4-digit year are handled correctly (e.g. 01-01-2000).
MS-DOS╥ file system APIs use a year offset from 1980 to store dates. When a program gets a date from an MS-DOS╥ API the program must add 1980.
Product compliance issues:
- MS-DOS cannot display a 4-digit date, using the DIR command (internal to COMMAND.COM).
- MS-DOS will not accept 2-digit date changes for the year 2000 and beyond. To enter the correct date, a 4-digit year must be entered to the DATE command (internal to COMMAND.COM). Failure to enter the correct 4-digit date will result in an "Invalid Date" error.
- External commands with switches that use a date parameter require years beyond 2000 to be entered using 4 digits.
Recommendations:
There are no patches available at this time and no plans to develop any patches. The commands described above are infrequently used and easily worked around. This date issue does not constitute a significant threat to the stability and/or functionality of the product as a whole.
Testing guidelines and recommendations:
Some PCs do have a problem that resets the system date to 1980 or other invalid dates when the computer reaches the year 2000. This problem is created by flaws in the computer hardware and in low-level BIOS software provided by other vendors. If users are going to test for this error, Microsoft recommends that executing the tests on a "test-bed" machine rather than a production machine. Please see the Windows Operating System Interactions with BIOS and Real Time Clock section in the Year 2000 white papers for further information.
