So, let me get this straight...

The only way (as far as we know) to tell that time exists, is by observing the difference in evolution between two entangled particles and the rest of the universe from a god-like perspective?

Not really. The arXiv blog has a better explanation than the link Devil provided [https://medium.com...].

So... since the observer can't distinguish between the particles from outside of the "universe", but they can inside, therefore time exists, because without internal observation (and therefore entanglement), everything appears static, because you can't distinguish anything from anything else?

Not really, no.

Combining the maths of relativity and quantum mechanics results in a bunch of bullschiesse and infinities and stuff. The Wheeler-Dewitt equation addresses a lot of that, but it introduces some new bullschiesse - the universe doesn't evolve with time. Then some science theorist guys did some stuff and decided that entanglement could solve this problem, and so observers entangled with the system would see the system evolve with time, but to observers outside the system the system would be static and unchanging. In other words, time exists within the system because of entanglement. The experiment did some stuff and the physicists are saying that yes, indeed - time is a side effect of quantum entanglement.
