off topic - why do you have different usernames?

Sorry but I don't understand what you're asking

I'm dumb, it was the "5 minutes ago" and then "4 minutes ago"

Eh, maybe I was primed, but it got me too for a second. I scanned for the usernames wondering what might be the issue, and then I noticed there was two users with similar names, k_12 and k_8 - that must be the confusion!

.. nope, I'm just dumb too. Hah :)

Because your username ends in an underscore, my brain wants to associate the number from the timestamp with your username. So I really want to read "k_ 3 hours ago" as "k_3" for your username.
