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.
Small one shows time for me, with m or d next to the number
The big one are the upvotes, yes. I saw some posts somewhere why they don’t always align but currently can’t find one to link to. The small one is time.
Right after posting it also show only “1” for me, just like in your picture. And the small dot right next to it.
