ntptrace(1M)                                                   ntptrace(1M)

NAME
     ntptrace - traces a chain of NTP systems back to the definitive timer

SYNOPSIS
     ntptrace [-dnv] [-o version#] [-r retries] [-t timeout] [server]

DESCRIPTION
     ntptrace establishes the location from which a specific NTP (Network
     Time Protocol) server obtains its time information and traces a chain
     of NTP servers back to the definitive timer. The command begins with
     localhost if no arguments are specified.

     Example of the output from the ntptrace command:

  % ntptrace
  localhost: stratum 4, offset 0.0019529, synch distance 0.144135
  server2.bozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
  usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'

     The fields (from left to right) in each line are: the system name, the
     system stratum, the time difference between this and the local system
     as established by ntptrace (for this reason the value for "localhost"
     is not always 0), the synchronization distance for the system, and the
     ID of the external timer (only for servers in stratum 1). All times
     are specified in seconds. (The synchronization distance is a measure-
     ment of the delay in transmitting the message to the partner.)

OPTIONS
     -d   Activates diagnostic tool output.

     -n   Specifies the IP address instead of the system name. This can be
          necessary if there is no name server running.

     -o version#
          This is used to communicate with the NTP package server with the
          specified version. The default value for version# is 3.

     -r retries
          Sets the number of job retries for each system. The default value
          is 5.

     -t timeout
          Sets the job response time limit. The default value is 2.

     -v   Outputs more detailed information relating to the NTP servers.
