When you arrive, in a very real sense, you have travelled a tiny fraction of a second into the future. Do the same thing around a neutron star and for you a few minutes might have passed but when you return to Earth, you could find yourself millions of years in the future with no way back.
Theroretically there is nothing forbidding time travel into the past but doing so can potentially cause so many paradoxes that many physicists believe that there will be some as-yet unexplained mechanism which will prevent it.

Are we getting closer to the sun? If so would an object with that mass be able to speed up time as we got closer to it? I'm sure at some part of the orbit we must be closer than others?
