error when echo date() format?
<p>I have a datetime with format: 2012-03-30 11:47:58</p>

<pre><code>$datetime = '2012-03-30 11:47:58';
$publishdate = date('m/d/Y H:i:s', $datetime );
</code></pre>

<p>When I <code>echo $publishdate</code> is result is <code>'01/01/1970 07:33:32'</code> , How to fix it</p>
