Other submission here https://news.ycombinator.com/item?id=28037039 . For some reason, algolia adds 10 hours to the submission time, this one that's 1 hour ago according to HN is marked as 11 hours ago, and the other that's 10 hours ago according to HN is marked as 20 hours ago.
>It's an artifact of the re-upping system. '1 day ago' was the original submission time and '1 hour ago' was the re-up time. Lots of explanation here: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que.... Sorry for the confusion!
