    Because the design goal behind W32Time was operability with
    Kerberos V5 authentication, and not keeping time accurate to the
    microsecond (as provided by the NTP protocol), developers chose to
    incorporate SNTP into the W32Time service running on primary
    servers and clients in Windows 2000. By using the SNTP protocol,
    W32Time meets the requirement of "loose synchronization" with
    other hosts on the network as specified in RFC 1510. The SNTP
    protocol ensures that all clocks in an enterprise are within 20
    seconds of one another, and all clocks in a site are within two
    seconds of one another.
