Out of ~100 emails from this group listing precisions in the modern format (ie, NTP-4.2.x), a histogram [1] of results is: 46 precision=-19 16 precision=-20 12 precision=-14 8 precision=-18 4 precision=-8 3 precision=-15 3 precision=-10 2 precision=-16 1 precision=-21 1 precision=-13 1 precision=-19 1 precision=-10 One might do better using 'ntpq -crv' against published NTP servers or pool members to collect data. Regards, -- -Chuck [1]: grep -hr 'precision' _IMAP_storage_ | sed 's/3D-/=/g' | sed 's/> //' | sed 's/>//' | sed 's/==/=-/' | awk -F, '{print $1}' | histogram.py | grep 'precision=-' ...and then trimmed a few stray matches, such as the Subject: header of this thread. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
