Meinberg SHSPZF LANTIME - Manual (Page 63)

The NTP Trusttime will specify the time how long the NTP will trust the reference
time if this is not synchronized (free running). This time will be set in seconds or
minutes or hours. The value 0 will be select the default value for the specific
reference clock. The default values are:
Lantime/GPS : 96 h
Lantime/PZF : 0,5 h
Lantime/RDT: 0,5 h
Lantime/NDT: 96 h
After each restart and after any change of configuration a new /etc/ntp.conf file is
generated by the LANTIME software. Any changes you made to this file are lost. In
order to use your custom ntp.conf (your LANTIME is using a standard version of the
NTP software suite, therefore all configuration parameters of the NTP software are
fully supported), you have to edit the file /mnt/flash/ntpconf.add, which is
automatically appended to the /etc/ntp.conf file generated at boot time or when
reloading configuration after a change. You can edit this file by using the button
“Edit additional NTP parameter”.
By choosing „Show current NTP configuration“, you can review the actual state of
the /etc/ntp.conf file. The file cannot be changed on this page, see above for a
description why editing this file is not reasonable.
