The shot of the ground shaking under Clark didn't suggest levitation or anti-gravity to me at all.
If Clark can time travel by flying fast enough in a certain way, without mechanical aid, it's an innate power. It's not a "side effect of speed," because he can (could) fly FTL without time traveling. That would be the same as calling his super-breath (a pretty ridiculous power, granted) a "side effect of respiration."

Wow, how full of oneself do you have to be to imagine that you are so right that the director of the actual film would deny your obvious rightness only because he's allegedly a prick now? That's an impressive rationalization.
