format time as "______ ago"

a lot of bloggy sites display time as this post was made X hours / X
days / X months ago. this is so popular I'm sure RoR has a built in
lib to do it, but I can't figure it out, searching google and the
docs. there's an ago function, but it returns a Time. I need like
the reverse. Is there one?
