Gravitational Time Dilation

General relativity predicts that clocks run slower in stronger gravitational fields.

Formula

t_far = t_near / sqrt(1 - 2GM / (rc^2))

where the Schwarzschild factor 2GM/(rc^2) is the ratio of the Schwarzschild radius to r.

On Earth's surface, clocks run about 0.7 nanoseconds per second slower than clocks far from any gravity.
