chrony.clk.XXX.sock is a new thing in gpsd 3.25: it gives you the time from
GPS serial messages (which is inaccurate but includes the time of day);
chrony.XXX.sock gives you the PPS information (which is accurate, but does
not tell you which second it is). See

On many recent Linux distros, /var/run is linked to /run.
