How the Stopwatch Works
Measuring Elapsed Time
The stopwatch functions by precisely measuring the time that passes after you hit "Start."
- Start: When you click "Start," the stopwatch records the current time as a starting point. It then begins an internal timer that fires every 10 milliseconds.
- Increment: With each "tick" of the timer, it adds 10 milliseconds to the total elapsed time. This is how the display updates so quickly and accurately.
- Pause/Resume: "Pause" stops the internal timer. "Resume" starts it again without resetting the elapsed time.
- Lap: When you click "Lap," the stopwatch calculates the time elapsed since the *last* lap was recorded (or since the start, for the first lap). This individual lap time is stored, but the main timer continues running uninterrupted.
- Reset: This stops the timer completely and resets the elapsed time and all recorded laps to zero.
Example
If you start the timer and click "Lap" at 15.50 seconds, Lap 1 will be recorded as 00:00:15.50. If you click "Lap" again when the main timer shows 40.20 seconds, Lap 2 will be calculated as 40.20 - 15.50 = 24.70 seconds, and it will be displayed as 00:00:24.70.
