Jquery :: Plugin Display From Unix Timestamp To Client's Local Datetime?

I did some search from the internet and check for jquery plugin that I can use so that I can display datetime base on clients local time. But not much seems to be what I'm looking for.Example like the facebook wall's post that posted datetime. It will display like 12 mins but as u stay on the page more than a min it will display 13 mins. Then for older post it will dispaly in more details like month, day, year, time, etc.
