COULD NOT TEST. IS THIS ACCURATE?
The timer icon is visible on both the mobileTMA Work Order and Post Labor windows.
The time is transferred to the related fields in WebTMA on the Quick Post > Labor by Technician window for the work order.
If you do not immediately post labor and instead open another work order, a message asks you to select Yes or No to stop the timer for the work order. If you select Yes, you lose the elapsed time on the first work order. If you select No, you cannot use the timer with the second work order. And, the time continues to accumulate and is added to the previous work order.
