Need Coding Expert Help For Minor Pop Under Script Adjustment

[PonderAbout]

Hi, I was wondering any coding expert is able to help me setup a timer code for the pop under provided by javascriptkit like the code below. It works fine, but I prefer for the pop under to kick in lets say in 2mins time after someone clicked on the link instead of immediately. Much appreciated for those who can help!

<script>

//Pop-under window- By JavaScript Kit
//Credit notice must stay intact for use
//Visit http://javascriptkit.com for this script

//specify page to pop-under
var popunder="http://yahoo.com"

//specify popunder window features
//set 1 to enable a particular feature, 0 to disable
var winfeatures="width=800,height=510,scrollbars=1,resizable=1,toolbar=1,location=1,menubar=1,status=1,directories=0"

//Pop-under only once per browser session? (0=no, 1=yes)
//Specifying 0 will cause popunder to load every time page is loaded
var once_per_session=0

///No editing beyond here required/////

function get_cookie(Name) {
  var search = Name + "="
  var returnvalue = "";
  if (document.cookie.length > 0) {
    offset = document.cookie.indexOf(search)
    if (offset != -1) { // if cookie exists
      offset += search.length
      // set index of beginning of value
      end = document.cookie.indexOf(";", offset);
      // set index of end of cookie value
      if (end == -1)
         end = document.cookie.length;
      returnvalue=unescape(document.cookie.substring(offset, end))
      }
   }
  return returnvalue;
}

function loadornot(){
if (get_cookie('popunder')==''){
loadpopunder()
document.cookie="popunder=yes"
}
}

function loadpopunder(){
win2=window.open(popunder,"",winfeatures)
win2.blur()
window.focus()
}

if (once_per_session==0)
loadpopunder()
else
loadornot()

</script>

You could try to replace

win2=window.open(popunder,"",winfeatures)

with something like

win2=setTimeout('window.open(popunder,"",winfeatures)',120000)
