NAME

     ntpctl — control the Network Time Protocol daemon

SYNOPSIS

     ntpctl -s all | peers | Sensors | status

DESCRIPTION

     The ntpctl program displays information about the running ntpd(8) daemon.

     The options are as follows:

     -s all | peers | Sensors | status
                   Used to display information about the running daemon.  Keywords may be
                   abbreviated.

                   all shows all data available.

                   peers shows the following information about each peer: weight, trustlevel,
                   stratum, number of seconds until the next poll, polling interval in seconds,
                   and offset, network delay and network jitter in milliseconds.  When the system
                   clock is synced to a peer, an asterisk is displayed to the left of the weight
                   column for that peer.

                   Sensors shows the following information about each sensor: weight, sensor
                   "good" status, stratum, and offset and the configured correction in
                   milliseconds.  When the system clock is synced to a sensor, an asterisk is
                   displayed to the left of the weight column for that sensor.

                   status shows the status of peers and sensors, and whether the system clock is
                   synced.  When the system clock is synced, the stratum is displayed.  When the
                   system clock is not synced, the offset of the system clock, as reported by the
                   adjtime(2) system call, is displayed.  When the median constraint is set, the
                   offset to the local time is displayed.
