Due to the time dilating effects of the gravity of the Sun (as predicted by General Relativity), how many seconds (or years?) slower is a clock on Mercury than on Earth, accumulated over the age of the Solar System?
How much time has the surface of the Earth lost compared to a clock in deep space far from any galaxies due to the gravitational time dilation of the Earth itself, the Sun, and the rest of the mass of the Milky Way galaxy? How much does each account for?
