STATUS - PTP
jitter: Jitter (also called timing jitter) refers to short-term variations in frequency with com-
ponents greater than 10 Hz.
stability: Stability refers to how well the SyncServer can maintain a constant frequency over
time. It is usually affected by aging, environment changes, etc. The value is expressed units
of parts per million (ppm).
broadcastdelay: The broadcast and multicast modes require a special calibration to determ-
ine the network delay between the local and remote servers. Typically, this is done auto-
matically by the initial protocol exchanges between the client and server. This is the
broadcast or multicast delay reported by the NTP daemon. The value is always set to 0.004
seconds on the SyncServer.
authdelay: When NTP authentication is enabled and performed on outgoing NTP packets,
this adds a trivial amount of fixed delay that can be removed based on the authdelay value.
This value is always set to zero on the SyncServer.
