The first time I heard of this being noticeable on a human timescale was the movie Interstellar. But I don't no think in real life there is that much of a difference between the rate at which time passes near a large mass.

This answer on Quora says the rate at which time passes on Jupiter is only a few nanoseconds off compared to Earth.

IIRC I read that for an outside observer everything that is sucked into a black hole does never actually pass "into" it. The closer it gets to the event horizon, the slower it's clock runs (from an outside perspective), and gradually stops upon approaching the horizon itself. [!] That seems like a rather large difference.

[!] Disclaimer: I don't know if that interpretation is still considered valid.

I read recently, I've forgotten where, that the cumulative time difference for the center of the earth (relative to the surface) is about four minutes.
