RACE RESULT 14 refers to the Start Time as T0, and this value is then used by all your Splits or Special Results settings to calculate the times. 

By default in all templates, the Start Times are set individually by each Contest, however, this value can be set according to any wave definition required. If you require a more advanced wave setup then see the guide on Multiple Wave Starts, if using this then you will need to navigate to the Start Times / Finish Time Limit page within the Timing Tab to set the Start Times. 

Set the Start Time for each Contest by clicking the Set button, this will use the time from your timing system to get the most accurate possible Start Time.

Alternatively, you can also manually type the time in the input box, this may be necessary if you have multiple Contests starting simultaneously and you need to ensure they all have the same Start Time. Start times should always be entered as a time of day, the times will be saved automatically when exiting the text box. 

Once the Start Time has been set then a timer will be displayed on the right-hand side showing the current race time. 

You do not need to take any additional steps to stop the race unless you have a time limit after which no more times should be counted. In this case, you can set the Finish Time Limit in the same way as the Start Time, this should also be entered as a time of day.
