Yes. There is a reason why we fiddle with stuff like leap-seconds instead of simply letting the second dilate ever so slightly, as Earth's rotation slows down ever so slightly, so that there are still exactly 86,400 seconds in a day. Since 1967, the second has been defined as 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.† The caesium atom is far more consistent than the Earth. †http://en.wikipedia.org/wiki/Second http://en.wikipedia.org/wiki/Second
