If a clock running in a high gravitational field runs more slowly than one
in a low gravitational field, would not a clock in thei extremely high
gravitational field (compared to earth's) of a distant star show much
_less_ elapsed time than one on the earth's surface? That would be
consistent with the second example above (satellite clocks)
