I would have expected Special Relativity to deal with the kinematic effect, but that General Relativity would have dealt with the Gravitational effect.

SR can only deal with the kinematics of constant velocities. When accelerations or gravitational fields are involved, GR is needed; and in its framework, an accelerating reference frame and gravitational field are equivalent, just as PH stated.

Was GR or SR cited in that post by PatrickHenry?

The reason I mentioned the special theory is that I believe time dilation can be determined with nothing more complicated than the Lorentz transformation. So I didn't think the General Theory was involved. I'm well aware, however, that the GT deals with gravity.

As always, I welcome corrections (I need them).
