DescriptionNot synchronized with NTP server defined in the Administration UI under System > Settings > System Management > NTP and Time Zone. This is confirmed by using the ntpstat command in the CLI.
Example:
> ntpstat
unsynchronised
polling server every 8 s
Solution1. Verify whether or not the NTP server specified in the Administration UI under System > Settings > System Management > NTP and Time Zone can be reached. In the CLI type
ntpq -p
The NTP server cannot be reached if:
"when" column = blank
"st" column = 16
Failed Example:
> ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
149.20.176.27 .INIT. 16 u - 1024 0 0.000 0.000 0.000
time.nullrouten .INIT. 16 u - 1024 0 0.000 0.000 0.000
2. If unable to reach the server, either troubleshoot why the server cannot be reached or
try changing the NTP server in the Administration UI to a known good one. If the NTP server is defined as a name, compare the resulting IP address listed in results for "ntpq -p". If different than a known good NTP server synchronization, try using the known good IP address.
3. Once the NTP Server has been changed in the UI and the system has been restarted, verify the server is now reachable.
Working Example:
> ntpq -p
remote refid st t when poll reach delay offset jitter

> ntpstat
synchronised to NTP server (162.159.200.1) at stratum 4
time correct to within 970 ms
polling server every 64 s
NOTE: ntpstat results may not show the system synchronized immediately. It may take several minutes.
If the system time is dramatically different than the NTP server, then simply synchronizing may not be enough to correct the time automatically. For instructions on correcting the clock, see related KB article below.
