Civil time is tied to Earth Orientation with a precision of +/- N hours, for values of N up to about 5. Civil time is tied to other governments notion of civil time with of +/- < N nanoseconds, for values of N less than 100. The "System Engineering" that went into this, clearly found it much more important to be able to compare time in London to time in New York, than to the position of the Sun and other celesial bodies. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
