- 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.
