// It is supposed to be 1 ten millionth...
well, it *was* supposed to be that, and yes they messed it up (and
then declared the error didn't matter!). currently (as of 1983),
it's defined as "the length of the path traveled by light in vacuum
durring a time interval of 1/299792458 of a second."
which has the nice reciprocal effect of defining the speed of light
rather nicely.
