Time dilation is a real physical effect and not an artifact of clock design or perception.

Is it true that time dilation is a real physical effect and not an artifact of clock design or perception?

Yes. Wikipedia's account of the Hafele-Keating atomic clock flights and GPS relativistic corrections, plus an arXiv analysis, show time dilation is a real physical effect that applies to all clocks, not an artifact of light-based clock design. A few non-peer-reviewed preprints dispute the conventional interpretation, but they present no new data.
