What happens if you orbit the solar system via FTL drive then come back?

I've always heard that FTL travel would be essentially going back in time, but it's conventionally used in terms of traveling interstellar distances. So, if you orbited the solar system via FTL travel (I chose the solar system just for the lower centripetal force vs. orbiting the earth at above light speed, I assume it would be too tight a curve), assuming this has been achieved, and we're talking say, Star Wars style hyper-drive rather than a warp/Alcubierre drive and somehow you just push on through light speed with propulsion, when you slowed down would you be in earth's past time frame?

Or would you just have wasted a bunch of time and energy? And of course now I'm realizing that this is basically the superman spins round the earth and it reverses thing from the movie (spoilers, that's what was supposedly happening there, backwards time travel). Sorry for the vague-ass initial question, and feel free to recommend I throw this at the physics boards.
