When they decided the 9,192,631,770 they did so with astronomical observations which were half a century old. If they had used a more up to date astronomical result, we would have had a lower rate of leap seconds, essentially getting rid of the "one leap second every 18 months" average value. In the long term it doesn't make a difference of course, there earths slowing down will dominate. -- 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.
