[time-nuts] New frequency standard, Mercury better than Cesium?

[Mike Feher]

I still think that the statement on TVB's website is the best. It is also
pretty much the truth. I am sure all of you on here are familiar with it and
it has to do with a man owning one clock vs. a man owning two clocks.  The
one with one clock always knows what time it is, the one with two is never
sure. That is truly a classic that I love. We are playing the same game. -

UTC is determined by using a large ensemble of clocks and weighting the 
individual clocks
contribution depending how much they varied from the average (or some 
such measure) The details
I don't remember :-)
