Product Details |
Description of how the product handles dates:
Storage. All dates are stored internally as 4-digit dates. MS-DOS« file system APIÆs are an exception. 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.
2-digit shortcut handling:
This is a function of the underlying MS-DOS« operating system.
More information on MS-DOS« 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.
The MS-DOS« DATE command is the only OS command that accepts datesûûthe Date/Time property within Windows uses a graphical interface. See the note above for the 2-digit logic. Also, since the MS-DOS« file system APIÆs return a year offset from 1980, the programmer has to add 1980 to the date value returned to get the correct date.
Product compliance acceptable deviations:
The date cannot be set to 02-29-2000 in the DATE/TIME control panel applet using the mouse. To work around this issue, use the keyboard to set the date on 02-29 of the year 2000. Note that the system does roll over to February 29 correctly. If the user does not touch the date/time control panel applet on the February 29, 2000, the machine will have the correct time and date.
Recommendations:
Microsoft is investigating the Date/Time control panel issue. No fix is available at this time.
Common date usage errors:
Some PCs reset 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 you are going to test for this error, Microsoft recommends that you execute the tests on a "test-bed" machine rather than a production machine.
Testing guidelines and recommendations:
Please see the white paper on Windows Operating System Interactions with BIOS and Real Time Clock at http://www.microsoft.com/technet/year2k/white/rtbios/rtbios1.htm.
