I already do time-interval comparisons (using a time interval counter and GPIB to log data onto a Linux machine) of the PPS between the Cs and GPS (and, soon, each other) so I have pretty good data on their performance (see http://www.febo.com/time-freq/plots for the semi-live data). I'm looking at NTP as an auxiliary method, with the idea of having a single network time source that represents the "best" time I can get from the ensemble. I don't *need* to do this, but since the tool is there, I thought I'd try to wring as much out of it as possible.
