Autoupdate java clock, time formatting

<div id="clock"></div>

<script>
var now = new Date(<?php echo time() * 1000 ?>);
function startInterval(){  
    setInterval('updateTime();', 1000);  
}
startInterval();//start it right away
function updateTime(){
    var nowMS = now.getTime();
    nowMS += 1000;
    now.setTime(nowMS);
    var clock = document.getElementById('clock');
    if(clock){
        clock.innerHTML = now.toTimeString();//adjust to suit
    }
}

This is my html code. I am a Java noob and basically found this here: PHP with javascript code, live clock. I want to adjust the format from "HH:mm:ss GMT+0100 (Romansk (normaltid))" to only "HH:mm:ss".

Try Moment.js:

clock.innerHTML = moment(now).format('HH:mm:ss');

Working Example.

BTW, you are using PHP time() to return server side time right? Just a hint, setInterval is not that accurate (see: How Accurate is Window.setInterval()) and so you will slowly introduce imprecision. If client side clock can't be trusted I would either expose the server time as Web Service or consume the time from one of the many web services already available (Time API, json-time, etc). While there will be a delay, at least it will not introduce cumulative imprecision.

now.toLocaleTimeString(false, {'hour12': false});
