The difference can be shown as days, hours, minutes, and seconds.
Worked Examples
Example 1: Two hours apart is 2 hours, 0 minutes, 0 seconds.
Example 2: One day and 90 minutes apart is 1 day, 1 hour, 30 minutes.
Example 3: Signed mode keeps the direction if the end moment is earlier than the start.
