As I've red, different points on the rotating disk, or rotating object have different velocities and so they should time dilate differently. Points on equator are for instance quicker than those in Scandinavia. When we take an inertial frame that has zero velocity with respect to the Earth as a whole (the Earth is rotating wrt to that frame but isn't moving inertially in any direction), we can observe that different points have different tangential velocities, so that points on Equator have different directions of motions, but same speed.
So my question is, if we take a frame that is traveling with some velocity wrt to Earth, how will the velocities add. I mean all points are traveling with a different direction, so how can we add their velocities to the velocity of our moving frame, and how will the time dilate wrt to that moving frame that I previously mentioned? And how will simultaneity be defined on that moving inertial frame considering the Earth as a worldtube that we're focused to? How will simultaneity differ between the moving frame and the frame which has the rotating points at rest?
I hope you understand my question.
