As you will note in the equation on the page I shared, time dilation is only a function of how fast a body is moving with respect to the speed of light. That is the time dilation due to relative velocity between two bodies. What I believe you are now asking for is time dilation caused by a clock experiencing a gravitational acceleration.Yup, this is what I was looking for.Thanks
Do you have the same for the time dilation caused by the gravity of the black hole?
