I have been chasing the sub-second differences between NIST computer display, RCC, GPS and watch with some interesting (and surprising) results. After considerable research I purchased a Kaito KA11 radio (small and reasonably priced) to receive the WWW time broadcasts. I also use the 30 fps video mode on my point-and-shoot digital camera to capture 2 devices simultaneously and count frames for difference. (Example: watch or RCC against computer screen.) Bill B
