Table 1-2 display ntp-service status command output description 

Clock status 

Status of the system clock 

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  

Actual frequency 

The actual frequency of the local system hardware clock  

Clock precision 

The precision of the system clock 

Clock offset 

The offset of the system clock relative to the reference source 

Root delay 

The roundtrip delay from the local device to the primary reference 
source 

Root dispersion 

The maximum error of the system clock relative to the primary 
reference source 

Peer dispersion 

The maximum error of the system clock relative to the reference 
source 

Reference time 

Reference timestamp
