I'm curious about what you are trying to find out with this
experiment.   Certainly it is not to prove that time does in fact
dilate.    Are you planning on using time to measure relative
differences in gravity?   That seems reasonable because as it turns
out times is the physical quantity that can be measured to the highest
precision.   It might be interesting to see how the rate of time
changes as a result of Earthquakes, magma circulating deep underground
or as the moon orbits the earth and the tides change.

I think the record for detecting time dilation using clocks in a 1
meter difference in elevation.   I'm sure someone here knows where
this was published.
