Only if you subscribe to the Copenhagen or similar interpretation of quantum mechanics. According to the "Many Worlds" interpretation, the explanations are fully local, but that interpretation isn't too popular by real physicists, though it's popular in Sci-Fi.

I thought that non-locality was already proven?
If the entangled particles were photons the time dilation wouldn't apply, but it would to particles with rest mass.

I don't think time dilation even applies. No information is actually "travelling". We are talking about that "spooky action at a distance" Einstein was creeped out by.
"Instantaneous" might depend on your reference frame. Events which are simultaneous in one reference frame may not be simultaneous in another.
It's instantaneous, I thought, regardless of space and time.
Events A, B, and C occur in different order depending on the motion of the observer. The white line represents a plane of simultaneity being moved from the past to the future.
The mainstream minds that believe in Copenhagen interpretation, which may be the most popular interpretation, say it's non-local, but as the video "Quantum Mechanics (an embarrassment) - Sixty Symbols" in this thread OP points out, it's not exactly a mainstream consensus, and the physicist making the video prefers "Many Worlds" interpretation though he admits he's in the minority, while pointing our that no interpretation got over 50% in the survey:

How has that been represented in entanglement? It was my understanding that mainstream minds agree that the collapse of an entangled system occurs outside of time. True temporal non-locality.
Bell's theorem depends crucially on counterfactual reasoning, and is mistakenly interpreted as ruling out a local explanation for the correlations which can be observed between the results of measurements performed on spatially-separated quantum systems. But in fact the Everett interpretation of quantum mechanics, in the Heisenberg picture, provides an alternative local explanation for such correlations. Measurement-type interactions lead, not to many worlds but, rather, to many local copies of experimental systems and the observers who measure their properties. Transformations of the Heisenberg-picture operators corresponding to the properties of these systems and observers, induced by measurement interactions, "label" each copy and provide the mechanism which, e.g., ensures that each copy of one of the observers in an EPRB or GHZM experiment will only interact with the "correct" copy of the other observer(s). The conceptual problem of nonlocality is thus replaced with a conceptual problem of proliferating labels, as correlated systems and observers undergo measurement-type interactions with newly-encountered objects and instruments; it is suggested that this problem may be resolved by considering quantum field theory rather than the quantum mechanics of particles.
