Häufig gestellte Fragen
How accurate is the browser stopwatch?+
Modern browser timers (using performance.now()) provide sub-millisecond precision. However, due to browser security measures against timing attacks, precision is typically limited to 5 microseconds - more than sufficient for any practical timing need.
Does it keep running if I switch tabs?+
Yes. The timer uses absolute timestamps rather than intervals, so switching tabs or minimizing the browser doesn't affect accuracy. The displayed time is always correct when you return.
