I don't think this is anything really new. The principle of general covariance in GR says that the laws of physics should remain invariant under a diffeomorphism. Since coordinate transformations are diffeomorphisms, and since time is relative, the equations of GR do not depend on time. Indeed, I think the search for a background independent theory of quantum gravity is exactly the approach taken by Loop Quantum Gravity.
