Recently developing a tool and I found this happed very common.

You can see https://news.ycombinator.com/item?id=21268584 is "5 hours ago", but from my tool(https://hn.okphp.com/?k=digital,postgres ) it is "3 days ago"(my tool is using official api timestamp)

I guess it is caused by re-posting. But the api returns the "time" the link first posted.
