How can the time dilation predicted by special relativity be confirmed in one reference frame, and contradicted in another reference frame?

In 1971, Joseph Hafele and Richard Keating used atomic clocks to test the prediction of time dilation resulting from motion (special relativity) and gravity (general relativity). In 1972,they...
