Is there a way to get chrony to produce statistics on the clock quality, without actually setting the clock?
I see the -Q option, but that only prints out the offset as a single shot. I'd really like better data, as in what would be reported by "tracking". Is there some way to do this? Or some reason why it would not be possible? I'm developing an embedded Linux device which has a custom inertial reference unit with a GPS. I have GPS time fixes (of rather unimpressive latency and jitter), as well as a PPS signal (remains to be seen how good it is) that is routed to an FPGA that is part of the SoC. The integrated FPGA means I can in effect design a custom PPS device for the SoC and then write a kernel pps driver for it. It will be interesting to see if anything can be gained there. In the final end use of the device, it won't be connecting to NTP servers and won't be acting as one either. So I'd rather not install an NTP server on it. It looks like with hardpps in the kernel it should be possible to get a good clock without using an application like ntpd or chrony. Should be possible, but is it? And how good? Thus the desire to measure the clock quality w.r.t. reference NTP servers, but not have chrony actually discipline the system clock.
