localhost
.
Here is an example of the output from
:
% ntptrace localhost: stratum 4, offset 0.0019529, synch distance 0.144135 server2ozo.com: stratum 2, offset 0.0124263, synch distance 0.115784 usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'
On each line, the fields are (left to right): the host name, the host stratum,
the time offset between that host and the local host (as measured by
ntptrace
;
this is why it is not always zero for
localhost
), the host synchronization
distance, and (only for stratum-1 servers) the reference clock ID. All
times are given in seconds. Note that the stratum is the server hop count
to the primary source, while the synchronization distance is the estimated
error relative to the primary source. These terms are precisely defined
in RFC-1305.
