There really isn't any excuse for adding static date in your footer any more, it's just so easy to add one via PHP.

We try to make it additionally easy for our theme users to add the current year. You just need to edit a textbox in theme options to customize the copyright message/footer links, and simply add in the [year] shortcode anywhere you want it to appear.

This shortcode can also be used across all posts/pages/widgets if needed too, without the user having to enter PHP directly.
