Out of interest, don't GPS receivers output a 1.000000000000 Hz signal from somewhere ?


You didn't read the article, did you? :o)

Most, but not all GPS receivers do indeed have a pps (pulse-per-second) output. This signal is usually within +/- 1µs from UTC, although there are special 'time receivers' that are much more accurate; somewhere in the order of 30ns!
