I suspect that what's happening is that some days after being submitted, some posts are pushed to the front page by the admins of this site.

  Usually via the second chance pool. The timestamp of the post and earlier comments are reset to a current time (probably to game HN’s own ranking system) and new comments will have correct timestamps. After a while all the times go back to their correct ones. https://news.ycombinator.com/pool https://news.ycombinator.com/pool Selecting “past” at the top of this submission can confirm this. It shows this submission with the same submitter, score, and number of comments but dated 4 days ago.

    What's the second chance pool and how does it work?
