Ntp clock server - Jun 27, 2022 · Basically from the perspective of a client, it is the number of servers to a reference clock. So a reference clock itself appears at stratum 0, while the closest servers are at stratum 1. On the network there is no valid NTP message with stratum 0. A server synchronized to a stratum n server will be running at stratum n + 1.
