Looking at the HN front page, some human-readable age labels ("10 hours ago") correspond with timestamp in title attribute<p><pre><code> <span class="age" title="2023-10-02T03:10:59">10 hours ago</span>
(provided now = 2023-10-02T13:11:33)
</code></pre>
but others are off, sometimes even by days.<p>For example current front page, archived "2023-10-02T09:36:17" [1] features post<p><pre><code> Astronomers discover thousands of red galaxy hearts with powerful radio signals
4 hours ago (title="2023-09-29T15:07:25")
</code></pre>
"4 hours" ago would be something in "2023-10-02", but title timestamp goes two days farther.

Sometime the mods cherry pick some posts a give them a "second chance", and they are send to the front page for a short time with a fake time. More details in <a href="https://news.ycombinator.com/item?id=26998308">https://news.ycombinator.com/item?id=26998308</a>
