Since we are on the subject... I came across this page the other day and am curious about what other's thoughts are about it.
http://tf.nist.gov/service/gpstrace.htm If I understand correctly looking at the graphs, they are saying the time from GPS is currently off about 24-30ns from the NIST frequency standard. So does that mean that a person wanting every last ns should adjust their delay according to the data on that page (and of course things like cable delay and other circuitry)?
