title: End-To-End Delay calculation in omnet++
body: <p>Dears, </p>
  
  <p>To calculate the end to end delay manual, i found can do this by bellow equation </p>
  
  <p><code>EED = current simulation time - creation  time of packet</code> .. </p>
  
  <p>So can any one advice me exactly what mean here ? i'm using omnet++ 4.6</p>
  
  <p>Thanks in advance  </p>
