He's probably interested in offset from his time reference, rather than 
the ntpd "offset" measurement, which could be optimistic, if there are 
asymmetric delays.

Intercontinentally he can probably tolerate several milliseconds or even 
   low tens of milliseconds without any risk that there is any doubt 
that two events are not causally related.
