Meaning of the values in the entry:
– Name or address of the peer
– Reference ID (0.0.0.0 if the reference ID is unknown)
– Stratum value of the peer
– Type of peer (local, unicast, multicast or broadcast)
– Number of seconds which have passed since the last polling cycle
– Polling interval in seconds
– Reachability Register (octal)
– Currently ascertained delay (runtime of the query), offset (time difference between the
reference time and the home system time) and the dispersion (order of magnitude of
the fluctuations) of the peer in milliseconds
The sign in the first column of an entry shows the status of this peer in the time selection

ntptrace
The ntptrace command provides information on where an NTP server gets its time and
traces the entire chain of NTP servers back to its origin
Sample call
ntptrace [NTP-server]
Here NTP-server designates the server from which the chain is to be traced. If no server
name is specified the chain starts with the local NTP server. Per element of the chain the
information output contains a line with the following entries (see also the example below):
– Name of the NTP server
– Stratum value of the NTP server
– Time offset (in seconds) between the NTP server and the local host
– Synchronization difference (in seconds) of the NTP server
– Reference clock ID (only for servers with stratum value 1)
