Field Description
Clock status
Status of the system clock, including
z Synchronized: The system clock has been
synchronized.
z Unsynchronized: The system clock has not been
synchronized.
Clock stratum Stratum level of the system clock
Reference clock ID
After the system clock is synchronized to a remote time
server, this field indicates the address of the remote time
server; after the system clock is synchronized to a local
reference source, this field indicates the address of the
local clock source:
z When the local clock has a stratum level of 1, the value
of this field is “LOCL”;
z When the stratum of the local clock has another value,
the value of this filed is the IP address of the local clock.
Nominal frequency
The nominal frequency of the local system hardware clock,
in Hz
Actual frequency
The actual frequency of the local system hardware clock,
in Hz
Clock precision The precision of the system clock
Clock offset
The offset of the system clock relative to the reference
source, in milliseconds
Root delay
The roundtrip delay from the local device to the primary
reference source, in milliseconds
Root dispersion
The maximum error of the system clock relative to the
primary reference source, in milliseconds
Peer dispersion
The maximum error of the system clock relative to the
reference source, in milliseconds
Reference time Reference timestamp
