DateTimeZone command stopped working when I switched to virtual server
<p>I used the following PHP code in shared hosting and it worked just fine:</p>

<pre><code>$tzFrom = new DateTimeZone('America/New_York');
</code></pre>

<p>Now I am trying to use the same code on a virtual server and I get this error:</p>

<pre><code>Fatal error: Class 'DateTimeZone' not found in /var/www/vhosts/...com/httpdocs/.../footer10.php on line 69
</code></pre>

<p>Any idea why it's not working on the virtual server?</p>

<p>Thanks in advance,</p>

<p>John </p>
