Um, no, if you actually did travel faster than light, the basic relativity equations would have time going backwards for you. Its just that this is impossible, as accelerating to reach lightspeed would require infinite energy.

Whether time travel is impossible or not is a matter of debate, complicated by the fact that just because something is possible, doesn't mean the mechanisms by which you could achieve it exist.
