    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.
