OpenCart - How do you increase the Admin session timeout?

Question

Currently the Admin session in OpenCart is about 30 seconds. I was wondering is there a PHP file or is there some way I can increase the timeout session for the login?

Currently I have been told this solution works but it does not:

<script type="text/javascript">
function pingServer() {
    $.ajax({ url: location.href });
}
$(document).ready(function() {
    setInterval('pingServer()', 60000);
});
</script>

This file has been placed in admin/view/template/common/header.tpl

This can most likely be solved simply by changing the value of session.gc_maxlifetime. You can change this via .htaccess, php.ini or even in your script itself (before the session_start())
