Lol.. you are genius.. You can "travel in time" by airplane, if you take an interconinental flight, its not science, just normal time adjustment across the world as we have the central time in London. Exact same thing would apply to the space if there were any central time set in one of all the planets.
This has nothing to do with physical time travelling, since you are not travelling through history. That would be possible if you traveled back in time in order to the "central time" which is same for everyone in the world ,since we dont know of any other civilisations in space anyway. Central time IS THE SAME FOR ALL PEOPLE NO MATTER HOW FAST AND WHERE YOU TRAVEL
If you traveled to other planets faster than light, the central time will be the same in London for people on the Earth and for you ..no matter what you do :-)))
Its pretty hard to understand for you brain Mr. Einstein, I know..
