I would have expected perhaps a global setting for how dates are displayed so that they are consistent across the site. But reading the referenced post, I see that is not the way. My use, right now, is for blog listings and blog posts.

I am running Version 7.1, but hope not to have to pay for a business account to get blog dates.
