So there are numerous ways to do this. You could have an onscreen time stamp with each scene (Young Justice, born out of the creators previous work, Gargoyles, having a series bible time stamp). You could start with the second scene, and play up until the scream is heard and then show a caption saying "24 hours early" and get the story up to the POV of the Screamer... I consider this lazy as most of these are easily converted to linear.
The TV show Archer frequently overlays dialog between scenes that fits both character's dialog perfectly, but may not be discussing the same events. Normally the first character in the second scene drops the appropriate final line of the last scene off screen, then the scene switches to that character, who continues the line of thought. Austin Powers used a similar joke where a rocket with a phallic shape is launched and is observed by various people on the ground, only to be cut off before the use a Euphamism for the male genitals, and the scene switches, starting with off with the euphamism used in an approriate context given the scene:
Husband: Honey, look up there points skyward What's that?
Wife: Why, it looks like a J-
Scene Switches to a man in high rise office
Boss: (yelling) Johnson! Get in here!
Johnson: Yes, sir, right away.
Boss: Do you have those reports I wanted.
Johnson: Yes, sir, they're all right... looks out the window What's that?
Boss: Quickly spins around and in shock My god. It's a giant W-
Scene switches to a boy stading on a Jetti waving out to sea
Boy: Willy! You're Free to live with the other whales! Teach them about Michael Jackson's songs for me, Willy! (and the gag repeats for many more times over the course of two films)
On "How I Met Your Mother", the story is framed as one of the characters, Ted, telling his teenage children the titular story (for eight years) as sort of a narrator. Frequently, the five characters of the core cast would be split up to do A-B story scenes and Ted would explain away the scenes he wasn't in as things that were told to him after the fact (Meanwhile, your Uncle Marshal was... insert summation of the situation) These were often parts of the show that allowed for a bit more the outrageous and probably exaggerated. In one instance, where Marshall was coaching a kindergarden Basketball team that was the worst in the league, Ted admits that "Marshal Swears that during the second quarter", and included the claim that the opposing team grew several feat (cue both teams running to one side of the court, Marshall making an anguished gesture, and his team running by a group of four grown men who would not look out of place in an NBA line up, all wearing appropriately sized uniforms of the former team) and one was Teen Wolf (Cue a guy in werewolf costume... also wearing the team uniform) following behind the group. It's not like this actually happened, but Ted wasn't there and Marshall will not back down from the exaggeration.
