i need to make this script ask users of confirmation when pushing submit button but when time is over i need the script to bypass submit confirmation and submit form automatically without confirmation. this is the script

Code:
<html>

<head>
 <script type="text/javascript">
<!--


function changeText2(){
var userInput = document.getElementById('userInput').value;
}
/* this is to show live time */

function show2(){
if (!document.all&&!document.getElementById)
return
thelement1=document.getElementById? document.getElementById("tick3"): document.all.tick2
var Digital=new Date()
var hours=Digital.getHours()
var minutes=Digital.getMinutes()
var seconds=Digital.getSeconds()
var dn=" pm"
if (hours<12)
dn=" am"
if (hours>12)
hours=hours-12
if (hours==0)
hours=12
if (minutes<=9)
minutes="0"+minutes
var ctime=hours+":"+minutes+dn
thelement1.innerHTML=ctime
setTimeout("show2()",1000)
}
window.onload=show2
function changeColour(elementId) {
    var interval = 1000;
    var colour1 = "#ff0000"
    var colour2 = "#ffffff";
