Tally code:

Ref. ID: It is the reference ID (0.0.0.0 if unknown).

Stratum: It is the place of the server in the 'clock strata' hierarchy. Stratum 1 systems are synchronised to an accurate external clock; stratum 2 systems derive their time from one or more stratum 1 systems, and so on.

Type: It is the type of the peer (local, unicast, multicast or broadcast).

Last arrived: It is the time value when the last packet was received.

Polling interval: It defines the period between two queries in seconds.

Reachablility: It is a register indicating the reachability of the peer. A peer is considered to be reachable if at least one bit in this register is set to one.

Delay: It is the current estimated delay in milliseconds.

Offset: It is the current estimated offset in milliseconds.

Jitter: It is the estimated time error of the peer clock (measured as an exponential average of RMS time differences).

Status: The status displays the syncronisation status of the NTP server.
