Agreed but the original idea was to measure frequency without a local
freq standard. If we have a local standard, it can be fed into the
time-base of any cheap counter to get accurate results. The idea was
to use a remote standard via NTP, synced and traceable to external
atomic standards, to achieve a reasonable degree of accuracy.
