I'm looking for a way to create a second-accurate countdown timer within an embed. I tried editing it every second, which didn't work at all (good at first, then edits would pile up and go all at once). I heard from a friend who knows a major bot developer that it was possible, but never got a reply on how to do it. If anybody has any solutions, that would be greatly appreciated!
Just posting this answer so I can close the question, there's no way to make what I wanted work.
