There is so much woo woo science in that article that its not worth reading in full.
Once I see reference to Time Dilation, Dark Matter or Energy, or Quantum anything, I quickly lose interest.
If you have a clock that is the most accurate, not losing a second since the Big Bang, (or some such claim), by what even more accurate time keeping device are you comparing it with to make such a claim?
Anyway, according to the idiot, Einstein, Time is just a persistent illusion, seconds for you are not the same for me, so why all the effort to measure an accurate second what the second is not a constant!
Its the height of foolishness.
Unless of course one realizes that the idiot Einstein's theories are as ridiculous as their author.
Clocks don't ever lose or gain time because TIME has changed, the change their rates because of changes in the Physical conditions around them. This is not TIME changing, its clocks becoming less accurate.
