•
Timestamps of latest time samples from this peer; actual timestamps displayed
depends on how the server is configured
•
Root reference at—Last time at which the stratum 1 server sent an NTP reply to
the server
•
Last request sent—Last time at which the system sent an NTP request to the server
•
Response/Broadcast was sent—Last time at which the server sent an NTP reply
or broadcast to the system
•
Response/Broadcast received—Last time at which the system received an NTP
reply or broadcast from this server
•
Sample buffer for this peer contains the following samples:
•
Delay—Round-trip delay from client to server
•
Offset—Difference between client’s and server’s clocks
•
Dispersion — Measure of the errors of the offset values, based on the round-trip
delay and the precisions of the system and the server
•
