I want the values to not change even when user refreshes the page

I have written a code in javascript for a timer which submits the form when time is up. The problem is if the user refreshes the page the timer is reset how can i avoid this from happening?

    <script type="text/javascript">
    var total_seconds = 6*1;
    var c_minutes = parseInt(total_seconds/60);
    var c_seconds = parseInt(total_seconds%60);

    function CheckTime()
{
    document.getElementById("quiz-time-left").innerHTML
    = 'Time Left: ' + c_minutes + ' minutes ' + c_seconds + ' seconds ' ;

    if(total_seconds <=0)
{
        document.forms['quiz'].submit();
    } 
else
 {
    total_seconds = total_seconds -1;
    c_minutes = parseInt(total_seconds/60);
    c_seconds = parseInt(total_seconds%60);
    setTimeout("CheckTime()",1000);
    }
}
    setTimeout("CheckTime()",0);
    </script>
