I think you can use js for this.We could set in a specific interval of time after which the page is to be refreshed.I will provide an example :
<html>
<head>
<script type="text/JavaScript">
function timeRefresh(timeoutPeriod)
{
setTimeout("location.reload(true);",timeoutPeriod);
}
</script>
</head>
<body onload="JavaScript:timeRefresh(10000);">
<p>This page will auto referesh in 10 Sec..... please wait </p>
</body>
</html>

I found good interactive idea here .
In brief, it does the following:
We define two functions: startTimer() for body onload event, it starts every 1000ms the second one - timeUp(). It increments global var timer and checks if it's equal to pre-defined timeout (180). If yes, reloads the page. If no, it puts the difference to "timer" div - so, the page looks like reverse timer.
<html>
<head>
<script type="text/javascript">
var timer=0;
function startTimer()
{
setInterval("timerUp()",1000);
}
function timerUp()
{
timer++;
var resetat=180; //change this number to adjust the length of time in seconds
if(timer==resetat)
{
window.location.reload();
}
var tleft=resetat-timer;
document.getElementById('timer').innerHTML=tleft;
}
</script>
</head>
<body onload="startTimer()">
Seconds until page reloads:
<div id="timer">
</div>
</body>
</html>
