Wouldn't matter, because the problem isn't about space or motion, but about position. If you jump backwards in time but your position in the universe doesn't change then you are probably no longer on earth because the Earth moves about the sun, etc. To land somewhere meaningful, you'd have to calculate the target location relative to some reference point with a predictable location and as Earthlings we'd probably pick the Earth itself unless this is a time traveling spacecraft.
