Oh, and our own beloved TVB whose time lab can keep UTC no worse than NIST or whoever owns the leapseconds.com domain. Once IERS ceases to allow the use of their IT resources to distribute leap second announcements, a new mailing list will need to be set up. Leapsecond.com is clearly a good

Yes, indeed. It has been nothing but trouble for us that the usual human circadian rythm is a couple of hours longer than 24 hours the planet currently cares to rotate in. The last I heard, it was just over 24 hours, and the original research that had turned up a figure of around 25 hours was
