Copyright shortcodes

I’m trying to add a footer with a copyright year shortcode, but it’s not working properly.

In my layouts/shortcodes/year.html template I have:
{{ now.Format “2006” }}

And in the config.json template I changed the .Site.Params.Description to:
© Copyright {{< year >}}, Pete Moore

But in my footer it shows the year code instead of the numeric result. Any idea what I’m doing wrong?
