Good to know
How is elapsed time measured?
The stopwatch calculates elapsed time from timestamps instead of counting interval ticks. It restores its start time after a refresh.
What is the difference between lap and total time?
Lap time is the duration since the previous recorded lap. Total time is the elapsed stopwatch time when the lap was recorded.
Does it keep time while I switch tabs?
Yes, it recalculates elapsed time on return. Changing the device clock can affect timestamp-based recovery.
