Field Description
reference
Reference clock ID of the clock source
1.
If the reference clock is the local clock, the value of this field is
related to the value of the
stra
field:
•
When the value of the
stra
field is 0 or 1, this field will be
“LOCL”;
•
When the
stra
field has another value, this field will be the IP
address of the local clock.
2.
If the reference clock is the clock of another device on the
network, the value of this field will be the IP address of that
device.
stra
Stratum level of the clock source, which determines the clock
precision. The value ranges from 1 to 16. The clock precision
decreases from stratum 1 to stratum 16. A stratum 1 clock has the
highest precision, and a stratum 16 clock is not synchronized.
reach
Reachability count of the clock source. A value of 0 indicates that
the clock source in unreachable.
poll
Poll interval in seconds, namely, the maximum interval between
successive NTP messages.
now
The length of time from when the last NTP message was received or
when the local clock was last updated to the current time
The time is in seconds by default. If the time length is greater than
2048 seconds, it is displayed in minutes; if greater than 300
minutes, in hours; if greater than 96 hours, in days.
offset
The offset of the system clock relative to the reference clock, in
milliseconds.
delay
The roundtrip delay from the local device to the clock source, in
milliseconds.
disper
The maximum error of the system clock relative to the reference
source.
