[ntp:questions] Is function time_pps_kcbind essential for PPS support?

2009-02-05 Thread Andrius Burokas (PPC)
Hello, I would like to know if the PPSAPI must implement the optional (by RFC-2783) function time_pps_kcbind? I see in the source, that without the function's implementation, the PPSAPI is not initialized. How does that affect the work with PPS interface 127.0.0.22? /* /ntpd/refclock_atom.c:

[ntp:questions] NTPd is not sync for some poll interval values

I have a problem where the NTPd would not sync the time with the timeserver (10.0.0.1) if minpoll value is 7 and maxpoll is 8. It works if the minpoll is 4 maxpoll is 5. Can anybody please help me out in identifying what the problem could be? The "flash" never becomes "0" I think. Also another h

[ntp:questions] like a kid with a new toy (PPS jitter)

2009-02-05 Thread Dave Hart
After close to a week of calibration, I fudged then flipped off noselect on my GPS+PPS refclock in the early minutes of the UTC day. It looks to me (from my limited perspective of no other local refclocks) that I've gone from single-digit milliseconds to double- digit microseconds accuracy. Looki
