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.
