I attached it, but it's an ugly code, no error checking, comments etc. This one will work only on FreeBSD (different load average and temperature polling than Linux), with ntp logs in /var/log/ntpstats etc. The version for Raspberry pi needs additional CPAN libraries, because it gets data from NTP Pool monioring website among other things, so I don't attach it. It will probably be easier to adapt FreeBSD version. I also attached my windows perl (strawberry) code for checking ntp client status (Meinberg software). > b) When collecting data for the phase error (offset) and jitter, what do you > use a reference time source to calculate these offsets?

The values are in ms. Cheers, Adam Kumiszcza
