Neither that text nor any other I have been able to find, guarantee that the integral (= long term average) of the frequency will converge on 60Hz, only that the instantaneous frequency will stay in an particular range. >tvb's data at http://leapsecond.com/pages/mains/ [...] That data confirms what I said: Maybe if you average over a couple of months, but the practical problems related to doing that are enormous. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ 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.
