About this tool
Press Start to begin timing and Stop to pause. The display shows minutes, seconds and hundredths of a second (MM:SS.cc). Start continues from where you stopped, so you can time several intervals in one session. Press Lap at any moment to add a line to the list; each lap shows the total time elapsed at that moment, not the time since the previous lap. Reset clears the clock and the lap list. After 60 minutes the minutes simply keep counting (for example 75:00.00); there is no hour display. Timing uses your browser's high-resolution clock and runs entirely on your device.
How to use it
- Press Start to begin.
- Press Lap to record the elapsed time.
- Press Stop to pause, then Start to continue.
- Press Reset to clear everything.
Common problems
- Lap times do not show the time per lap
- Each entry is the total elapsed time. Subtract the previous lap to get the split.
- Laps stay after stopping
- The list is cleared only by Reset.
- The time looks stuck in another tab
- Display updates pause while a tab is hidden, but the elapsed time is still correct when you return.
