Facebook-style date/time display helper? (RESOLVED)

[eluser]IsaacS[/eluser]
Hi everyone,

Does anyone know of an extension to the Date helper in CodeIgniter that allows for Facebook style dates? eg:

Just now/a moment ago
1 hour ago
2 days ago
5 months ago

It would be even lovelier if it was customisable, and utterly cliché-producing if it could do things like fortnights

I've had a look on Google, but there's only lots of rubbish that comes up, which makes finding this helper a right pain.

I'm hoping that the Date helper has this built in, and I just haven't noticed?

Thanks!

Isaac
