Confused about time expiration

Hi, everyone. Im a little confused about this. The time is correct...however, when it shows the time expiration it is 5 hours behind. Does anyone know what could be the problem? Thanks.

Code Java:

function validateTime(timeStr) {
// Checks if time is in HH:MM:SS AM/PM format.
// The seconds and AM/PM are optional.
	if(timeStr == '') return false;
	timeStr = timeStr.toUpperCase();
	var timePat = /^(\d{1,2}):(\d{2})?(\s?(AM|am|PM|pm))?$/;
  var pm_times = 0;
	var matchArray = timeStr.match(timePat);
	hour = matchArray[1];
	minute = matchArray[2];
	ampm = matchArray[4];
	if (ampm == 'PM' && hour < 12) pm_times = 12 * 3600;
	return pm_times + (hour * 3600) + (minute * 60);
}
 
$(function() {
	$('#nav').droppy({speed: 130});
  var options1 = {format: '%I:%M:%S %p'  }
$('#jclock1').jclock(options1).addClass('ui-state-active ui-corner-all');
 
 
$('#timeout').everyTime(5000,function(i) {
  var cookiename = 'time_left=';
  var ca = document.cookie.split(';');
  for(var i=0;i < ca.length;i++) {
    var c = ca[i];
    while (c.charAt(0)==' ') 
    c = c.substring(1,c.length);
    if (c.indexOf(cookiename) == 0) {
      var data = c.substring(cookiename.length,c.length);
      data = unescape(data.replace(/\+/,' '));
      data = 'Session expires<br/>at ' + data;
    }
  }
  $('#timeout').html(data);
}).addClass('ui-state-error ui-corner-all');
