The value in the Next Run Time field in Task Scheduler is incorrect on a Windows Vista-based computer
On a Windows Vista-based computer, you create a scheduled task that has repetition settings. When you examine the next run time of the scheduled task, the value of Next Run Time field may be incorrect.
For example, you create a daily scheduled task as follows:
- The task starts at 7:00 A.M. and has a 1-hour repetition interval.
- The repetition duration of the task is set to 3 hours.
In this example, the task is expected to be triggered to start at 7:00 A.M., 8:00 A.M., 9:00 A.M. and 10:00 A.M.
However, after 10:00 A.M., you notice that the value in the Next Run Time field in Task Scheduler is incorrect. This problem occurs even though correct information appears in the Trigger field in Task Scheduler. In this example, the correct value of the Next Run Time field is 7:00 A.M. the next day.
The issue also occurs if you export the scheduled task and then import the task to another Windows Vista-based computer.
