If it were supposed that time were a 4th non-spatial dimension how would it influence the gravitational movement ?

The problem I have when trying to solve this invented problem is that newtonian physics works in coordinates and that there are a lot of ways to find 4d 3+1 hyperbolic-spherical coordinates.

Which one should be used to start the calculations ?

Newton-Cartan gravity however is at the level of dynamics fully equivalent to Newtonian gravity as you know it (to answer the question in the OP).
