title: Javascript Date getTime() code snippet with mysterious additional characters
body: <pre><code>&lt;script language="JavaScript"&gt;
  var t = new Date();
  t.getTime() + -864e5;
  &lt;/script&gt;
  </code></pre>
  
  <p>What is that funky code after the "+" at the end of the second line doing?</p>
  
  <p>It is probably made to be hard to understand, since I suspect it's one of the ways they try to protect themselves against scraping.</p>
