you can also get the ce using zend_fetch_class() API function. So the
code would look something like

zend_class_entry *ce = zend_fetch_class("DateTime",
   sizeof("DateTime")-1, ZEND_FETCH_CLASS_DEFAULT TSRMLS_CC);

if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC,
                          "O", &obj, ce) == FAILURE) {
    return;
}

When referencing an internal class it should be enough to do the fetch
just once and cache the value inside your extension.
