Timeago is a jQuery plugin which enables you to display fuzzy timestamps. And, the timestamps are auto-updated.

Some example timestamps are "5 minutes ago, about 2 days ago".

JavaScript Timestamps

Using Timeago is very functional for displaying more friendly timestamps and auto-update feature makes it more accurate when a page is opened for a while.

P.S. John Resig also has a similar solution named JavaScript Pretty Date.
