Wrong!  Gravity affects time the same as relativistic speed.  The greater
the gravity field, the slower time moves.  In fact, time stands still
inside a black hole.

As for the "problem" of spatial displacement for a time traveler, have it
anyway you want.  Since backward time travel is impossible, the argument is
academic.
