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.
