I changed my iPhone language to German (Österreicher) recently because I want to learn as fast as possible and surround myself with the language. I noticed that in the Instagram DMs, under a person's name it says, e.g. "Gesehen PM40 Mittwoch". I understand that it means something like "seen Wednesday at [some time here]".
For the life of me, I cannot find what PM40 means and what it is. I suppose it's some way of AM/PM time tracking, or PM could stand for 'Private Message', but what does the 40 mean? Or any other number, as I have messages that say 38, 36 and so on.
I understand this might be a dumb/obvious question but I’m genuinely confused.
Thanks in advance :)
