Javascript must be enabled to use this page. Both the stopwatch and timer have been tested to 60 minutes and are accurate to less than one second. The timer requires the start time to be entered in the format: 00:00:00. The timer/stopwatch window must be onscreen in the foreground - no other windows can be active - otherwise the clock accuracy is faulty.
