popstat=5946422755;
poprate=2.4452;

offset = today.getTimezoneOffset()*60*1000
diffpop = (( today.getTime() + offset ) - statsdate.getTime() ) / 1000
var newpop = Math.ceil(popstat + (diffpop * poprate));
newpop = "" + newpop;
p1 = newpop.substring(0,1)
p2 = newpop.substring(1,4)
p3 = newpop.substring(4,7)
p4 = newpop.substring(7,10)
var pops= p1 + "," + p2 + "," + p3 + "," + p4;
var popul = document.getElementById("poo");
popul.innerHTML = pops;
setTimeout('counter()',200); } </script>
