title: I'm using filemtime and it keeps returning the following numbers: 1302021664. Why is this?
body: <p>When I use the following command:</p>
  
  <pre><code>$arrDIR[$filename] = filemtime($filename);
  </code></pre>
  
  <p>It will return "1302021664" for all the <code>$filename</code>s in the array <code>$arrDIR</code>. Is this suppose to be some kind of date or something?</p>
