Menu: Stratum of local clock
The local clock is only chosen as the NTP time reference after the GPS clock lost
its synchronisation. The stratum level of this local clock is set to 12, this ensures that
clients recognise the switchover to the local clock and are able to eventually take
further actions. The local clock can be disabled if the timeserver should not answer
anymore when the reference clock is out of order. The field “Stratum of local clock”
is used to change the stratum level of the local clock (see above), default is 12.
Menu: Reset Time
If the time of the reference clock has changed (e.g. while testing with different
times) the system time has to bet set with the time of the reference clock and the NTP
has to be restarted.
