<p>Getting time on TCP port 37 is <i>old</i>. I only do it because that is all I have until such time as I port something smarter. Note the following from NIST: "We will continue to support the "TIME" protocol that uses TCP port 37 for the forseeable future."
So not responding on port 37 might not be a false negative, if only NTP is supported.<o:p></o:p></p>
