bws92082 on "How to remove " X days ago" from selected blog posts"

I have a WP blog using a theme and need to have a general blog post (top ten list) always at the top of the page. I'm positioning this one-post blog at the top of the page with a another different multi-post blog below it. This is working fine but the top blog shows "28 days ago" etc which I don't want here because it implies the entry is old and stale (even though I update it weekly). How can I remove this "days ago" field from the top blog while leaving it for the blogs below? (Perhaps it can be changed here only to "Last Updated" or something else?)
Thx.
