human_time_diff for 'years ago'?

I’m setting up a blog where I’m archiving all my posts from different blogs from the the past years. It’s basically an archive blog. Now, I’m looking for a way to make the timestamp show something like ‘5 years ago’. I found out about human_time_diff but all the searches only lead me to hours, days, months ago. Is there a way to make it show years ago as well?
