* (Master)—System is synchronizing to this server
# (Master - unsynchronized)—System has chosen this server as master, but the
master has not yet synchronized to UTC
+ (Selected)—System will consider this server when it chooses the master
- (Candidate)—System may consider this server when it chooses the master
x (Unusable)—Server does not meet the initial criteria for master
p (Preferred)—Server that you specified as the preferred server
~ (Configured)—Server is a configured server; no tilde indicates a broadcast server
Peer Address—IP address of server
Stratum—Number of hops between the server and the accurate time source
Poll—Time between NTP requests from system to server
Reachable—8-bit number that shows whether or not the NTP server responded to
the last eight requests from the system; one indicates a response, zero indicates no
response. For example, 11111111 indicates that the NTP server responded to the last
eight requests. If the system reaches one server less often than it does other servers,
that server is not a good choice for the master.
Precision—Length of the clock tick (interrupt interval) of server's clock
Delay—Round-trip delay, with the lowest dispersion value in the sample buffer,
between the system and the server
Offset—Difference, with the lowest dispersion in the sample buffer, between the
system's clock and the server's clock
Disp.—Lowest measure, in the sample buffer, of the error associated with the peer
offset, based on the peer delay
