I imagine this depends on the platform to some degree, but I have an #ActivityPub question: Is the home timeline chronological on post publish or when your instance becomes aware of the post?
For context, @posts sometimes publishes a post with a publish time well in the past (like right now, for instance, the most recent post delivered to followers (just now) has a publish time which was 18 hours ago. Does this show up in your feed now, or never get seen because the feed files it away chronologically with all the other 18 hour ago posts?
