Stratum of the NTP servers on the MMB
The stratum of the NTP servers on the MMB is the value of stratum + 1 of the synchronized
external NTP servers. Unless the NTP servers synchronize with external NTP servers, the
stratum is 5.
external NTP servers. Unless the NTP servers synchronize with external NTP servers, the
stratum is 5.

Support for leap seconds
The NTP on the MMB has no function for inserting leap seconds. Therefore, if you want to
associate the MMB time with leap seconds, you need to synchronize it with an external NTP
server that supports leap seconds.
If the NTP client on the MMB is set to Step mode, and the external NTP server slowly changes
the time for the leap second adjustment, the MMB time may be adjusted with the Step adjustment
when a time difference outside a range of -0.128 to +0.128 second occurs. To prevent the leap
second adjustment from using Step adjustment, use Slew mode.
