Transfer Speed calc

When I am uploading from my localhost it display wrong amount transfer data per sec.

Below is the script I have found on this site, but.

Code:

---

// Declarations
var totalBytes:Number = 0;
var uploadedBytes:Number = 0;
var uploadedBytes2:Array;
var startTime:Number;
var sec:Number;



// On that function/event
fileRefListener.onOpen = function (fileRef:FileReference):Void {

// timer is starting here
startTime = getTimer();

}

// Note this is fileRefListener.onProgress event, when the file is uploading
fileRefListener.onProgress = function (fileRef:FileReference, bytesLoaded:Number, bytesTotal:Number):Void {

// Calculate time in 1000 when the file is starting to upload, just a simple
// timer
var millisecsPassed:Number = getTimer() - startTime;

// Here is the core of the rate calc, uploaded data devided with
// the time that has passed from start.
var rate:Number = Math.round(uploadedBytes/millisecsPassed);
 
//Time to finish, total data
// divided with amount of data loaded.
ElepsedTime = Math.round((totalBytes/rate));

// Output to the stage
Time.text = "Time remaining: " + time_to_string(ElepsedTime-millisecsPassed);
Speed.text = "Transfer rate: " + GetSizeType(rate) + "/sec";
UpTime.text = "Elepsed Time: " + time_to_string(millisecsPassed);

}




//Converters Below, finished functions I found on internet.

// Converts data
function GetSizeType(size:Number)
{
        if(size < 1024)
                return int(size*100)/100 + " bytes";
        if(size < 1048576)
                return int((size / 1024)*100)/100 + "KB";
        if(size < 1073741824)
          return int((size / 1048576)*100)/100 + "MB";
        return int((size / 1073741824)*100)/100 + "GB";
}

// Converts raw time (timer()) 1000 to hundredths, seconds
// minutes and ahours

function time_to_string(time_to_convert) {
        elapsed_hours = Math.floor(time_to_convert/3600000);
        remaining = time_to_convert-(elapsed_hours*3600000);
        elapsed_minutes = Math.floor(remaining/60000);
        remaining = remaining-(elapsed_minutes*60000);
        elapsed_seconds = Math.floor(remaining/1000);
        remaining = remaining-(elapsed_seconds*1000);
        elapsed_fs = Math.floor(remaining/10);
        if (elapsed_hours<10) {
                hours = "0"+elapsed_hours.toString();
        } else {
                hours = elapsed_hours.toString();
        }
        if (elapsed_minutes<10) {
                minutes = "0"+elapsed_minutes.toString();
        } else {
                minutes = elapsed_minutes.toString();
        }
        if (elapsed_seconds<10) {
                seconds = "0"+elapsed_seconds.toString();
        } else {
                seconds = elapsed_seconds.toString();
        }
        if (elapsed_fs<10) {
                hundredths = "0"+elapsed_fs.toString();
        } else {
                hundredths = elapsed_fs.toString();
        }
//        return hours+":"+minutes+":"+seconds+":"+hundredths;       
        return +minutes+":"+seconds;
}

I can upload the file so its seasier for you to understand. If you like the originals code and my modifications just take it ;). But please try help me with this problem :S.

Becouse of the attachment limit I have uploaded in a free hosting site. Link for download is below.
