Auto-Refresh page at Specific Intervals

This will do a refresh once an hour:

<script language="JavaScript">

<!--

if (document.images)

    setTimeout('location.reload(true)',1000*3600); // forces a reload from the server

else

    setTimeout('location.href = location.href',1000*3600);  // just reloads the page

//-->

</script>

Alternative

Use

<meta http-equiv="refresh" content="3600;URL=name-of-this-page.html"> 

Some browsers might not understand the abbreviated form.
To refresh at 5 minutes past the hour according to the user's system clock:

<script type="text/javascript">

  var timer = setInterval("checkTime()", 1000 * 60 * 60);

   function checkTime()

  {

    if(new Date().getMinutes() == 5)

      self.location.reload(true);

  }

</script> 

This will not work if the user's browser doesn't support JavaScript; the meta-refresh will.
better of placing both since some browsers disable meta refresh:

<meta http-equiv="refresh" content="3600;URL=thesamepage.html"> 

<script type="text/javascript">

theHour="1"; //Input the hour

setTimeout("location.reload()",theHour*1000*60*60)

</script>

and for the 5 minutes:

<meta http-equiv="refresh" content="300;URL=thesamepage.html"> 

<script type="text/javascript">

theMinutes="5"; //Input the minutes

setTimeout("location.reload()",theMinutes*1000*60)
</script>
