Like everyone else, I have some RC clocks and a wrist watch which all keep good time. I have aligned my bedroom clock with the window through which presumably the signal will come. I put my watch about 6 inches from the clock, but I've noticed that the signal it picks up is often about 0.5 sec in front of the clock. Lately I've experimented with different positions for the watch and found that when it is aligned exactly in line with the clock they both have exactly the same times to some minute fraction of a sec.
I don't understand the physics of this. The signal can't be different for different distances from the window, can it? Or is something else going on?
