Vlad The submission date from posts on the likes of Reddit, Hackernews, Tildes, Twitter, Mastodon, etc., is what I would consider relevant. It would surprise me if a lot of people disagree with this.
I feel pretty sure I've seen these issues with other sites than Reddit as well, and that I've then compared it with Google to see it do it correctly. I'll be sure to post screenshots and details as I come across them again.
