Re: [chrony-users] Chrony not taking SOCKET data from Application

[sarveshwar k <sarveshwar.kt@xxxxxxxxx>]

Hi Miroslav Lichvar,

I see the reference time of GPS is taken by Chronyd, but not synchronizing the system clock.

Can you please suggest if any configuration changes required?

PFA of the output of chronyc tracking and the chrony config file.

Thanks & Regards

Hi Miroslav Lichvar,

I have set poll 0 for refclock SOCK. When I checked the date command I still didnt see the GPS time taken.

As GPS time is today date which I am sending to chronyd, I see chronyd is not syncing to that time. I still see system time is not the date and time that I have sent through SOCK.

Should I have to change configuration to achieve this? Does refclock_sock.c file APIs wont get called to read the sample from GPS, as I used the structure defined in this file.

Thanks & Regards

'?' for the SOCK refclock is expected with the noselect option. You
can set poll to 0 to see the reachability register filled more quickly
after start.

The log shows PPS samples accumulated, which means both the PPS and
the locked SOCK refclock are working.
