There are lots of plugins that will add a message to your posts when they're greater than a specific age (say, 2 years) but that isn't what I wanted - after switching themes and generally rebuilding this site a lot of images were broken, etc. I went through the posts, fixing them, until a specific age - I therefore wanted to highlight any post before a fixed date (i.e. where I'd got to). This, simple piece of code, does this.
Add to your theme's
functions.phpand, obviously, change the message and date to taste.
