Hello, We have a 1PPS input to the NIC and we're planning to run chrony to use 1PPS as an additional refclock, in addition to getting time of day via NTP. When we tried this out, we're not entirely sure if things work fine as the source that gives time of day shows up as "unusable" in `chronyc sources`. For example:
.-- Source mode '^' = server, '=' = peer, '#' = local clock. / .- Source state '*' = current best, '+' = combined, '-' = not combined, | / 'x' = may be in error, '~' = too variable, '?' = unusable. || .- xxxx [ yyyy ] +/- zzzz || Reachability register (octal) -. | xxxx = adjusted offset, || Log2(Polling interval) --. | | yyyy = measured offset, || \ | | zzzz = estimated error. || | | \ MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== #* PPS0 0 4 377 13 +50ns[ +136ns] +/- 18ns ^? foobar 1 5 377 9 +543ns[ +633ns] +/- 1824ns Is the above expected or are we missing any additional configs? For the PPS refclock's options, all we have are refid and poll. Thanks, Abhijith
