title: Getting unix timestamp
body: <p>Its a pretty simple question but I couldnt find nothing about it.</p>
  
  <p>I would like to get the current unix timestamp in seconds, I would like to get the identical result as the PHP's <code>time()</code> function.</p>
  
  <p><code>System.Now</code> returns full date with the current time.</p>
  
  <p>How can I achieve this in vb.net?</p>
