title: Measure message transmission speed
body: <p>I am making a network application and I would like to display the time messages take to travel from sender to receiver. </p>
  
  <p>What ways you believe are fit to implement this feature ?</p>
  
  <p>What I have thought is storing the current time on message and comparing with time on receiver end. Although on java doc it says the current Time given might be different depending on OS.</p>
  
  <blockquote>
    <p>How should I get the current Time so that it will be same on every OS?
    (or just OSX and win)</p>
  </blockquote>
  
  <p>p.s: The application in most cases is about just sending messages and not expecting something back.</p>
