I don't think the time rate is changed by gravitation. There are many kinds of clocks, atomic, gravitational, mechanical, chemical, or even biological. Their time rate varies to bi-direction with gravitation change. The test should proved light velocity change. That is, from up to bottom...

GR predict that a photon climbing in the Earth's gravitational field will lose energy and will consequently be redshifted. A test was done by Pound and Snider in 1965 using the Mossbauer effect They measured the redshift experienced by a 14.4 Kev rays from the decay of Fe in climbing up...
