I agree with Chris that the use of 
NTP to synchronize clocks at a distance 
is something that is suitable for a CPA 
and that the use of NTP
or XNTP or whatever could be 
advertized in a CPP. I also agree
that putting the mshTimeAccuracy 
in the MessageHeader 
is definitely excess baggage!
Should be removed.
