title: microtime to standard date format
body: <p>I Have some values which are milliseconds since epoch i.e. <code>microtime(true)</code> in my MySQL database these are got out as strings I need to convert them over to a standard PHP date()</p>
  
  <pre><code>$updated = 1349697975.9381;
  $nUpdated = date($updated, "l jS F \@\ g:i a");
  </code></pre>
  
  <p>This is returning a blank string, anyone help?</p>
