Published On: December 4, 2025
It is possible to enter and display negative durations in time fields. The system supports negative time values such as -36:00:00.

To enter a negative duration, simply type a minus sign (-) before the time value. The system interprets and displays the minus sign correctly when the field is used for duration tracking.
