Your statement about dark matter is absolutely correct, of course, but the point is that until 1970's they didn't even know there was something odd about the rotational speed of galaxies. Who knows what odd things are as yet unobserved. I agree, though, that there are no known unknowns that might be explained by some new, odd behaviour of time.
What? By any reasonable measure, cosmology's greatest all-time unknown involves T=0, at the start of the universe. If dark time (or whatever you want to call it) theory could explain how the universe came to exist without having a beginning, it would surely represent mankind's crowning scientific achievement. Loop quantum time, anyone?
