<?php echo date(‘H:i:s’);?>

ve tarih

<?php echo date(‘j F Y’);?>

But i am getting the following error on typing the command : http://localhost/time.php

An error occured trying to access document or resource /time.php.
Please contact the server administrator if the problem is abnormal and persists.
