Hi list, I recently got time to build my first stratum-1 GPS timeserver around a raspberry-pi (first model) and one of these [1]. I would ideally like to have it work as a completely standalone time source, only getting timing information from the GPS signal it is receiving (no network peers). As such, I built ntpd with --with-NMEA, and tweaked things around to the point where I *think* I got it working, however, my simple question is:
Can somebody tell me whether it's *actually* working? :) The output I get from "ntpq -c pe -c as -c rl" on the system [2] is confusing me a little since I see the GPS source being selected as sys_peer, but the event showing says "no_sys_peer". Is this expected in case no network source is available? The last section of the output furthermore shows a difference between the "reftime" and "clock" fields. Should I understand that reftime is the GPS time and "clock" the state of the system clock? In that case, should I see the clocks converge over time? I apologize if these are easily answered by reading a manual somewhere - like I said, it's my very first venture in the world of timekeeping, and I would benefit from having somebody explain things to me. Thanks for your time - Chris Links: --------- [1]: http://ava.upuaut.net/store/index.php?route=product/product&path=59_60&product_id=95 [2]: http://pastebin.ubuntu.com/12631346/ _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
