NTP server issue?

Tue May 09, 2023 6:47 pm

may/06 13:36:52 system,critical,info ntp change time May/06/2023 13:36:52 => May/07/2023 12:30:20

I've never seen a change more than a few seconds that I recall, but I seldom have to reboot the hAP ac.
I didn't realize my 2nd server seems to be the active one until I ran this command.

/system/ntp/client> pr
enabled: yes
mode: unicast
servers: 208.75.88.4 ,128.138.141.172
vrf: main
freq-drift: 8.075 PPM
status: synchronized
synced-server: 128.138.141.172
synced-stratum: 1
system-offset: -2.105 ms


I just looked at our standard here in America
https://tf.nist.gov/tf-cgi/servers.cgi
and see the NIST prefers using time.nist.gov so I'm switching to that.

That is a pretty substantial change. Likely related to the reboot.

Quite normal. From my observation, the router will use one member of the list and stay on that member of the list until that one fails (for any reason). Then it will try another member of the list, and if that one works, it will stay on that one until it fails.

I have my own stratum 1 NTP server so I point to that with a friends server as the second on the list.

Are you sharing your NTP server with the underserved? Be careful how you answer, governor gruesome is watching....
