TMGR: Zero Work Causes Task Start Time at 12:00 AM

MORE INFORMATION

The start time for a task with zero work is set to 12:00 AM because the task does not have to be scheduled with any other tasks. If the work on the task is increased above zero, the task is scheduled based on the other tasks in the team file.

You can force the time to be other than 12:00 AM by setting an Exactly On date. To do so, select the task, click Task properties on the Edit menu, click the Scheduling tab, click to select Exactly On, and enter a date.
