Split Lap Timer Features

Split Lap Timer Controls

Split Lap Timer Buttons

There are three timer control buttons.  These buttons can also be triggered using keyboard keys.  See Keyboard Controls in Settings section below.

Start / Stop Button -- Starts and stops timer.  Shows Start when timer is stopped, Stop when timer is running.  Timer counts from where it last stopped, so you can stop and start the timer multiple times.  Timer will stop at 99:59:59 if it ever gets there.

Split Button -- Records a time point.  If the timer just stopped, and you click the Split button, the time point when the timer was stopped will be recorded.  You can achieve faster splits using the keyboard versus the mouse.  See Keyboard Controls, in Settings section below.

Reset Button -- Resets the timer to zero, the 'start time'.

Time Data


The time data field shows your time splits.  Each click of the Split button or the split keyboard key generates a time data record.  You can edit the time data, and you can select, copy and paste the data into other programs.   Keyboard Controls are disabled when typing in the time data area.  To enable again, click outside the time data area.

The Reset button normally appends a new time data series to the end of the time data.  The Clear on Reset option will cause all the time data to be cleared out each time you reset the timer.

The Clear link above the text area, only clears the time data area and sets the split count to zero.  It does not reset the timer.

The Show radio buttons lets you see the time data in an expanded or truncated form.  The time data is not rounded.  If you select a different radio button after editing the time data, the time data will be re-displayed in the new format, and any edits you have made to the time data will be cleared out.  The Time Format radio buttons let you select between 1:35 (hours, minutes, seconds) or 95 (just seconds) for displaying the time values.

The time data is not stored.  Refreshing the timer page, or closing your browser, will clear out all of your time data.


Split Lap Timer settings can be viewed and changed by clicking the Settings link to the right of the Start / Stop button.  All setting changes take effect immediately, and you can change the settings while the split lap timer is running.

Setting changes are automatically saved when you change then using browser cookies.

The Default Settings link, resets the settings to the default state.

Our Split Lap Timers have our highest level of accuracy.  Each second, the timer checks and makes adjustments as needed.  But with that said, the accuracy of each computer's internal clock will affect the accuracy of the timer.

  Most device internal clocks are relatively accurate, but they can drift a few seconds a day, and we have no control over this.  It is up to you ascertain the accuracy of your computer's internal clock and our timer on your PC / tablet / phone.  In the event your device internal clock is accurate to your satisfaction, we still do not guarantee that any of our timers will be accurate, or that our code is bug free or virus free.
