Example 2: Subtracting Time (Crossing Midnight)
Start Time: 08:00 Operation: Subtract Duration: 10 hours Result: 22:00 (previous day)
This mode calculates the duration between two times, always showing the shortest possible duration.
Calculation Process:
Converts both times to total seconds
Calculates absolute difference
If difference > 12 hours, shows 24 hours – difference (shorter duration)
Converts back to HH:MM:SS format
Example 1: Standard Difference
First Time: 09:00 Second Time: 13:30 Difference: 04:30
Example 2: Difference Crossing Midnight (Shows Shorter Duration)
First Time: 23:00 Second Time: 01:00 Difference: 02:00 (not 22:00)
