NAME

ntpctl — control the Network Time Protocol daemon

SYNOPSIS

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.
