Following calls a functions every 10 seconds. It does not call the function immediately, just after the first 10 seconds.

window.setInterval(function(){
  /// foo
}, 10000);

How do I call the function first, then call it every x seconds, what would be the best way of doing this?

Either give it a name and call it right after the setInterval

function repeat(){
//foo
}

window.setInterval(repeat, 10000);
repeat();

Or use setTimeout instead and call it from inside the function

function repeat(){
 //foo
 setTimeout(repeat, 10000);
}
repeat();

<html>
    <head><title>Timeout testing</title></head>
    <body onload="callMe()">
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

    <script type="text/javascript">
    function callMe()
    {
        window.console.log('called');
        window.setTimeout(callMe, 1000);
    }
    $(".realContent").click(function() {

         var data = [ {"id":1,"start":"/Date(1401993000000+0530)/"} ];
         var myDate = new Date(data[0].start.match(/\d+/)[0] * 1);
         myDate =  new Date(myDate.getTime() + myDate.getTimezoneOffset() * 60 * 1000);
         alert(myDate);


    })
    </script>
    </body>
