Last tweet with JS

JavaScript
1

Hi everyone,

to display my last tweet on my page I use :

$.getJSON("http://twitter.com/statuses/user_timeline/username.json?callback=?", function(data) { 
     $("#twitter").html(data[0].text); 
});

However I wish to display the date of the tweet (‘45 minutes ago’…) as well.
How to do that ?
