Routine Description:

    This routine converts an NtTime value to its corresponding Fat time value.

Arguments:

        This should only be done *once* in the lifetime of a timestamp (important

        If true, rounded up. If false, rounded down to 10ms boundary. This obeys
        the rules for non-creation time and creation times (respectively).

    FatTime - Receives the equivalent Fat time value

    TenMsecs - Optionally receive the number of tens of milliseconds the NtTime, after
        any rounding, is greater than the FatTime
