That doesn't make any sense, this video was published days ago. I watched it then.
If you're on a desktop browser instead of a smartphone, you can use F12 Dev Tools to inspect the parent post[1] elements to see that the original timestamp is still there as "2024-12-26T05:23:25 1735190605" ... which is actually about 4 days ago.
Some search engines (bing) still has a cache of this thread we're in from 4 days ago.

If one were to click on that 4 day old thread, you come here where all the comments are "x hours ago". It's confusing.
