I'm still quite new to JavaScript so excuse me if my question sounds stupid.
JavaScript is worlds apart from Object Pascal and I'm still finding my way
around.
I'm working on a JavaScript clock that will show the time for all major
Australian cities. I'm not sure how to approach the whole timezone offset
thing. I know there is a function getTimezoneOffset() but I'm not sure how
to implement it.

Here's a piece of code (implementing time for two cities only at this
stage). I would appreciate it someone could demonstrate how I can implement
an offset. Perth is 3 hours (or 180 minutes) behind Sydney, so how could I
implement the time difference?

function SydClock()
   {
   var SydTime=new Date();
   var SydHours=SydTime.getHours();
   var SydMins=SydTime.getMinutes();
   var SydSecs=SydTime.getSeconds();

    if (SydHours>=13)
      SydHours-=12;
    if (SydHours==0)
      SydHours=12;
    if (SydSecs<10)
      SydSecs="0"+ SydSecs;
    if (SydMins<10)
      SydMins="0"+ SydMins;
      {
    ClockFrm.SydDisplay.value=(SydHours + ":"
       + SydMins + ":" + SydSecs);
       setTimeout('SydClock()',1000);
       }
    }

 function PerthClock()
   {
   var PerthTime=new Date();
   var PerthHours=PerthTime.getHours();
   var PerthMins=PerthTime.getMinutes();
   var PerthSecs=PerthTime.getSeconds();

    if (PerthHours>=13)
      PerthHours-=12;
    if (PerthHours==0)
      PerthHours=12;
    if (PerthSecs<10)
      PerthSecs="0"+ PerthSecs;
    if (PerthMins<10)
      PerthMins="0"+ PerthMins;
      {
     ClockFrm.PerthDisplay.value=(PerthHours + ":"
       + PerthMins + ":" + PerthSecs);
       setTimeout('PerthClock()',1000);
     }
   }

Thanx in advance!
