Should have something to do with Cloudfare/Cloudflare, when the page cant be loaded it'll show u a snapshot of an older version of that page? I'm not exactly sure why you're getting the "generated 79 mins ago". Edit: I was wrong^ It's just because you're browsing through pages which were generated 79 mins ago
If you actually type the URL into the bar and then enter it will refresh it. It's always done it, same with todays posts and posts by user.
