Bob just stated a great truth that explains why and how we become 
time-nuts -- in order to characterize an oscillator, you need another 
oscillator that's (preferably 10x) better.  Then you need one that's 10x 
better than *that*, and so on until you have a strontium optical lattice 
clock.  And then you need three of those to cross-check each other. :-)
