So? I do not think you understood what I was saying. Again: There is no universal clock to compare yours to. All you can say is that elsewhere, with a different energy density, clocks will run at a different speed and by how much.
I understand what you saying. You're refusing to understand what I'm saying.
It is the depth of the gravitation field that causes time dilation. That makes time dilation additive.
How do you keep a fool busy? Turn upside down for answer.
