'Spooky action at a distance' could create a nearly perfect clock

"There's even speculation that so-called absolute constants in the world of physics, such as the speed of light or the charge of electrons, may change as the universe expands. And because these constants define the laws of physics that govern the energy levels in an atom, they may also change the measurement of time, he said. So it's possible that "the very essence of time changes as the universe expands."

I will wait and see. This could be fun here or a big headache :)
