Listening to changes made to flex Date Object

I have a date object and I want to listen to any changes made to it. The changes can be made by either directly assigning another date object 

var newDate:Date = new Date(2009,10,9);
date = newDate;

and by using 

date.setTime(timeInMilliSeconds)

I tried using BindingUtils.bindsetter:

var myWatcher:ChangeWatcher = BindingUtils.bindSetter(updateDate,date,"time");

private function updateDate(value:Number):void
{
    trace(value);
}

but this doesn't seem to work. I wish to know what am I doing wrong or if there is someother way to do this.

Thanks!

You could use the PropertyChange / PropertyChangeEvent mechanism.

objectProxy = new ObjectProxy(newDate);
objectProxy.addEventListener(PropertyChangeEvent.PROPERTY_CHANGE, propertyChangeHandler);

private function propertyChangeHandler(evt:PropertyChangeEvent):void {
    // Do what you want
}

The code above is an excerpt from an example found at blog.flexexamples.com.

You have to make a variable bindable before you can watch it (or you need to dispatch the change events for it yourself).
