While in Test Mode the time of the decoder can be set via the Time menu. The following options are available:

Set Running Time 

The time entered will be set and start running even while being in Test Mode. This option is usually used to set the clock time / time of day.

Set Start Time

The time entered will be set, but will not start running before starting the Timing Mode. This option is usually used to set the time to 0:00:00.

Set GPS Time  

When using this option the system will try to receive the precise time from a GPS satellite. It may be that the GPS signal cannot be received inside buildings and under trees. In this case the system will show an error message after 60 seconds.

Configure GPS Time  

Within the configuration you can set the time zone the decoder should use and adjust the value for Leap Seconds (this is normally only required when working with third-party hardware which does not correct for Leap Seconds).
