How is it that you are determining NIST time? GPS? Time on your computer? An "atomic clock?" I ask this because there can sometimes be a delay between true time and the display of time. Early GPS receivers (ie, let's say ones manufactured in the 1990s) were infamous for time lags in their display software. Similarly, PC-based computers by default display time derived from a server at Microsoft; Microsoft's site has at times had a significant delay from true time.
If the NIST clock were off I believe there would be significant chaos in this country -- everything from the Internet to power grids depend on microsecond accuracy "time" -- and it would be front-page news.
