>There was some discussion of transmitted vs. paper time scales. This is another outdated notion. Paper time-scales only exist because we couldn't do any better when we had to wait for the astronomers to mail a letter to Paris with their observations. Today with realtime global clock comparisons available, both GPS phase and point-to-point via sat/fiber, the only contribution in the "paper" version provides, is that it allows us to use a non-causal weighing algorithm (ie: one which reduces a clocks weight earlier in time for something it did later.) For all practical purposes we could dismiss with paper clocks and go real time, but I'm sure astronomers will tell us that would do things to the cows milk or something... -- 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] https://pairlist6.pair.net/mailman/listinfo/leapsecs
