Intuitively, I want the speed of time to be isotropic. But there are strong indications that it is not! Intuitively, I don't want the speed of light to be isotropic. But there is excellent evidence confirming that it is. What effect does it have, if I just swop the names? So now my clock ticks away a set distance, over a variable length of time! Does doing this rescue my poor intuition?
