detected as real switchover (debouncing).

Stratum
Each NTP server is synchronized by a high-precision time standard or by another NTP server. The stratum is the
position of the NTP server in the hierarchy of NTP servers polled by the device. The best stratum is 1, each
further level in the NTP server hierarchy increases the stratum by 1.

Together with the IP address of a device, the subnet mask defines which IP addresses the device searches in its
own network.
