Use of clone function in actionscript 3.0

Question

I am learning MVC Design pattern. and i got confused in clone function .can any one help me why this clone function is used and how it works.
the code is below
package mvc{
public class Time {
private var _hour:uint;
private var _minute:uint;
private var _seconds:uint;
public function get hour(){
return _hour;
public function set hour(value:unit):void{
_hour = value;
public function get minute(){
return _minute;
public function set minute(value:uint):void{
_minute = value;
public function get seconds(){
return _seconds;
public function set seconds(value:uint):void{
_seconds = value;
public function Time(hour:uint, minute:uint, seconds:uint){
_hour =hour;
_minute=minute;
_seconds=seconds;
public function clone():Time{
return new Time(_hour,_minute,_seconds);

Answer 1

If you created an instance of your time class that you called myTime
var myTime:Time = new Time(15,15,0);
and later you wanted another instance with the same time you could write
var myTime2:Time = myTime.clone()
It is just there for convienience and doesn't have anything much to do with MVC
