切换到虚拟服务器时，DateTimeZone命令停止工作

Question

I used the following PHP code in shared hosting and it worked just fine:

$tzFrom = new DateTimeZone('America/New_York');

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

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

Any idea why it's not working on the virtual server?

Thanks in advance,

John

DateTimeZone was introduced with PHP 5.2. Your Virtual Server is likely running a previous version. Check the PHP version on the server and upgrade PHP on the server.

Note that support for PHP 5.2 ended on Dec, 9th, 2010. All users of PHP 5.2 are encouraged to upgrade to PHP 5.3. To prepare for upgrading to PHP 5.3, now that PHP 5.2's support ended, a migration guide available on http://php.net/migration53, details the changes between PHP 5.2 and PHP 5.3.
