Of course they have.

You can put an atomic clock on Southwest Airlines and measure the error you 
caused at the other end by being out of the gravity well and traveling at

You can just leave one in the basement and one at the top of a skyscraper 
for a couple months and measure the difference.

Assuming X and Y are both the same distance from Z when you start counting, 
why wouldn't they? Even with regular waves, that'll happen.
