The Windows NT Backup program sometimes displays and logs a time different than the actual local time at your computer. This only occurs in countries with a daylight saving time (DST) schedule different from the United States' DST.

Backup does not take the actual DST settings on a computer into account, but instead always assumes U.S. DST to be in effect.

The result is that when you run Backup in a country with a different DST from the U.S., during the overlapping period, an incorrect time is reported in the Backup log.

Daylight saving time in the U.S. is active between the first Sunday in April and the last Sunday in October. Daylight saving time in the Netherlands is also active between the first Sunday in April and the last Sunday in October:

Some countries use a shorter daylight saving schedule, however. Because Backup assumes U.S. residency, incorrect times are displayed in countries that do not have daylight saving time or are on a different schedule for daylight saving time. Times are reported as expected when the time schedules are back in synchronization.


   Current date :
   Current time : 11

Backup reports 12 as the current time.


Microsoft has confirmed this to be a problem in Windows NT version 3.5. A fix to this problem is in development, but has not been regression-tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for more information on the availability of this fix.
