Synchronizing with server time - jquery countdown plugin and php -

-

i have following code in php file:

<div id="clocktimestamp" class="hidden"><?=$_server['request_time'];?></div>   <div id="clock"></div>

i using jquery countdown plugin keith wood , calling this:

$('#countdown').countdown({until: until, serversync: getservertime});

and following code in js file:

function getservertime() {      var time = $('#clocktimestamp').html()*1000;     time = new date(time);      return time; }

now, question is: approach $_server['request_time'] ok or should this:

function getservertime() {      var time = null;      $.ajax(     {         url: '../../_ajax/getservertime.php',          async: false,          datatype: 'text',          success: function(text) {              time = new date(text);         },          error: function(http, message, exc) {              time = new date();          }     });      return time; }

i'm sure you've solved now, later visitors....

the easiest way use jquery server time plugin
