JScript - Time Zones Example

Local Time
California
New York
Slovakia
Jerusalem
GMT

Implementing this script:
Add the following functions to the Header section.

speed=1000;
len=50;
tid = 0;
num=0;
clockA = new Array();
offsetA = new Array();
dd = new Date();

function date_format(date)
{
  var d = date.getDate();
  var m = date.getMonth() + 1;
  var y = date.getYear();
  var hrs = date.getHours();
  var mins = date.getMinutes();
  var secs = date.getSeconds();
  
  if(y >= 2000){
    y -= 2000;
  }
  
  if(y >= 100){
    y -= 100;
  }

var mmm = 
    ( 1==m)?'Jan':( 2==m)?'Feb':(3==m)?'Mar':
    ( 4==m)?'Apr':( 5==m)?'May':(6==m)?'Jun':
    ( 7==m)?'Jul':( 8==m)?'Aug':(9==m)?'Sep':
    (10==m)?'Oct':(11==m)?'Nov':'Dec';

return "" +
    (d<10?"0"+d:d) + "-" +
    mmm + "-" +
    (y<10?"0"+y:y) + " " + 
	(hrs<10?"0"+hrs:hrs) + ":" +  (mins<10?"0"+mins:mins) + ":" + (secs<10?"0"+secs:secs);
}

function start() {
   clockA[num] = document.forms[num];
   offsetA[num] = 0;
   if (num == 0)  
      tid=window.setTimeout("doDate()",speed);
   num++;
}

function startLong(diff) {
   clockA[num] = document.forms[num];
   offsetA[num] = (diff - dd.getTimezoneOffset())*60*1000;
   if (num == 0)  
      tid=window.setTimeout("doDate()",speed);
   num++;
}

function cleartid() {
   window.clearTimeout(tid);
}

function Clock() {
   document.write('<FORM name=form'+num+'><br><input name=date size=');
   document.write(len);
   document.write(' value="Clock: Requires Javascript"></FORM>');
   start();
}

function ServerClock(diff) {
   document.write('<FORM name=form'+num+'><input name=date size=');
   document.write(50);
   document.write(' value="Clock: Javascript"></FORM>');
   startLong(diff);
}
//-->
</script>

Next, in the Body section, use the Clock() or the ServerClock(PARAM) functions to dynamically create text fields with the Time Zones. PARAM is the required time difference
{60 = +1 Hour, 120 = +2 Hours, (-60) = -1 Hour, etc, etc....}

Example:

<table> <tr> <td width="190" height="20"> <div align="right"></div> <div align="right"><b> <font color="#FFFFFF">Local Time</font></b> </div> </td> <td width="10" height="20"> </td> <td width="480" height="20"> <script language="JavaScript">  </script> </td> </tr> <tr> <td width="190" height="20"> <div align="right"></div> <div align="right"><b> <font color="#FFFFFF">Slovakia</font></b> </div> </td> <td width="10" height="20"> </td> <td width="480" height="20"> <script language="JavaScript">  </script> </td> </tr> <tr> </table>
