Big one is upvotes I guess? Or not… It correlates only sometimes. The small one I have absolutely no idea.
Edit: Thanks everyone for answering! The big one is upvote rating and the second one is time. Regarding no letters: My guess is - it doesn’t show “m” or “h” near the time because my system is not in english, and though most of the lemmy is in english, for some reason the time on a post renders only “sometimes” in my system language or doesn’t render at all.
Upvotes and time, 1 being one minute, if you find that post again I’d assume it’s about 8 hours later also, assuming that wasn’t an older pic.
