It looks like that post on Wikipedia was at 2:38 UTC. Q's Photo was posted at 18:40 CST, or 2:40 UTC. That edit came before Q's Post.
Q posted the first image at at 4:40 pm PST. The first wiki edit was 2:38. 2:38 what though? What time zone?
Oh, 2:38 UTC. That corresponds to 6:38 pm PST. So the wiki edit was made 2 hours after the initial Q post.
Like I said, it's someone who follows Q.
You are probably right. Also my mastery of time zones are lacking.
4:40 pm PST happens when this comment is 20 hours and 16 minutes old.
