You're being gaslighted by the second-chance pool. When a submission doesn't gather many upvotes, but the mods think that it would have fared better if it had been posted at a different time, they arrange for it to be reposted. That's implemented by messing with the timestamps, which can be confusing when you've seen the submission before.

You can see the true timestamp for this submission here: https://news.ycombinator.com/from?site=interocitors.com and for 3131s's comment here https://news.ycombinator.com/threads?id=3131s

I wonder how well that second-chance pool works. The visit counter at the bottom of the page is currently at 05247.
