Sure.  My point is I haven't seen a use case in this thread for nanosecond
*accuracy* relative to the TAI paper clock.  Actually I haven't seen a use
case for anything -- just some wishful thinking.  Getting and keeping a GM
in (sub)nanosecond phase with any national lab would appear to be a much
larger problem than worrying about which lab you decide to use as a label
on the side of the box.
