Cannot change task's start time due to the time is automatically set.
Cause:
The start time for a task is automatically set for 12:00 AM (midnight) on the start day of the task. The start time only affects the task when a reminder is set.
Solution:
To workaround the problem: set the reminder for the task at the desired time for the task to start. The start time will not change but the reminder will be set for the desired time.
1) Select the task to edit in the 'To Do List'.
2) Select the 'Edit' menu and select 'Edit Item...'. (The Task dialog box appears.)
3) Click the 'General' tab.
4) Select the 'Set Reminder' check box to set the reminder.
5) Type the number in the 'For' box.
6) Click on the down arrow.
7) Select the time increments from the drop-down list box.
8) Click 'OK'.
