title: Delphi: WSALookupServiceNext, get device detection time
body: <p>I am working on a script to detect device arrival time using bluetooth. </p>
  
  <p>The  problem is <code>WSALookupServiceBegin</code> takes up to 7 seconds to scan nearby devices, so <strong>device detection time limits to scanning start time</strong> (This makes detection time doesn't accurate so much). I've searched a lot but it seems that scan time can't be changed.</p>
  
  <p>Can I get the time that device is founded during scanning time?</p>
