Re: [chrony-users] Not getting time from gpsd

Not really Chris. I don't see a sock option in your configuration file. Gpsd should write time out to a device file some where and chrony can read the time from that device file via a Unix domain socket. Like I said..look into the sock option and how it relates to gpsd.

I'd look closer at the SOCK option under the refclock section. https://chrony..tuxfamily.org/manual.html#refclock-directive
