    How do you determine "spot on" over a three-day period?"
    
    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.)
