$srvstamp = time(); // ---- server timestamp ---- 
$twheader = get_headers($request_url, 1); // ---- array with ['Date'] string 
$twistamp = strtotime($twheader['date']); // ---- twitter timestamp 
echo " Server: ".date("Y.m.d (H:i:s)",$srvstamp)." - ".$srvstamp." \r\n"; 
echo " Twitter: ".date("Y.m.d (H:i:s)",$twistamp)." - ".$twistamp." \r\n";
