Ask HN: Why is the "Who is hiring?" post being re-aged?

I noticed that the August 2026 "Who is hiring?" post currently shows it's 1 hour old when opened from the front page. All the comments themselves are also under 1 hour old as well..

But if you check from the whoishiring account submissions it is properly tagged at 8 hours old https://news.ycombinator.com/submitted?id=whoishiring

Why would comments/posts get re-aged like this? Do any other posts/comments get re-aged?

thanks! was just wondering. maybe some issue with the implementation of manual movement of posts.
