problem with jalali date

CFDB uses a block of code for the purpose of converting dates to jalali. code is located in CF7DBPlugin.php:

// See if wp-jalali is active and if so, have it convert the date
// using its 'jdate' function
else if (is_plugin_active('wp-jalali/wp-jalali.php')) {
	$jDateFile = WP_PLUGIN_DIR . '/wp-jalali/inc/jalali-core.php';
	if(@file_exists($jDateFile)) {
	    include_once($jDateFile);
		if (function_exists('jdate')) {
			//return jdate('l, F j, Y');
			if (CF7DBPlugin::$customDateFormat) {
				return jdate(CF7DBPlugin::$customDateFormat, $time);
			}
			else {
				return jdate(CF7DBPlugin::$dateFormat . ' ' . CF7DBPlugin::$timeFormat, $time);
			}
		}
	}
}

the above code looks for a file which no longer exists. jdate function is automatically loaded and there is no need to include the file containing it. Hence I think changing the above code with the following would be appropriate.

// See if wp-jalali is active and if so, have it convert the date
// using its 'jdate' function
else if (is_plugin_active('wp-jalali/wp-jalali.php')) {
	if (function_exists('jdate')) {
		//return jdate('l, F j, Y');
		if (CF7DBPlugin::$customDateFormat) {
			return jdate(CF7DBPlugin::$customDateFormat, $time);
		}
		else {
			return jdate(CF7DBPlugin::$dateFormat . ' ' . CF7DBPlugin::$timeFormat, $time);
		}
	}
}
