New Atomic Clock 1000 Times More Accurate 313
stevelinton writes "The UK National Physical Laboratory has a new atomic clock potentially 1000 times more accurate than current cesium clocks: to within 1 second in about 30 billion years!
This could lead quite soon to a new definition of the second, and in a while to improved resolution in GPS successor systems. More interestingly, there are theories that some of the universe's fundamental dimensionless constants may have changed by a parts in a million over the last 10 billion years or so. These clocks are so accurate that they should be able to detect these changes over a year or two."

Now all we need is a13 year old to update the wikipedia entry.

Ah - but I suspect that measurement of what comprises six inches will be as imprecise and inaccurate as it's always been.

This "accurate" clock you describe is only exactly right every few billion years..
