Physicists Just Entangled A Pair of Atomic Clocks Six Feet Apart
Few things in the Universe keep the beat as reliably as an atom's pulse.

So if you have two entangled clocks and send one on a long space journey would they keep the same time?
That's a good question, but then another one comes up: our idea of time is based on our seasons, the sun, the moon and how we divide our planet in timezones. The civilisations two million lightyears away may have a completely different concept of time or even none at all (since time is an illusion and top most a description of change). In that light, the answer would be no or probably not. So, is time more contextual than a fact?
The clocks would still have the same beat, yes.
The problem being that quantum physics and relativity are in conflict over this one.
They are working on it! :-)
