@karinjiri You can usually hover and it will show you the actual datetime. Works for GitHub, mastodon, reddit, etc.
@karinjiri Reddit had it in 2005, years before GitHub was even a thing.
@karinjiri I think Ruby on Rails did it first, or at least widely popularised it as a default, and GitHub always was (still is?) built with Rails.
@sanityinc @karinjiri Ruby on Rails is from 2004. That’s really recent when it comes to discussion forums and systems deriving from those forums.
The Swedish discussion forum type KOM, in use from 1978 (older than Usenet) and still in use today, uses relative time in most of its implementations. It’s however somewhat unclear if it did this from the beginning or not. All archives are dumped much later than the posts, so they would show full date anyway.
@ahltorp @karinjiri Interesting - thanks for sharing! I wonder if the Scandinavian heritage influenced DHH's choice in that regard. I don't remember seeing support for that style baked into any earlier framework.
