1. The exact date and time at which the level known as Final Destination seen in all Super Smash Brothers' series took its first form within the "World of Light".

2. A timestamp that will only be confirmed to exist through chatboxes of given Public Access Network livestreams in 2069.

3. A timestamp that induces great existential anxiety about humanity's current prospects of survival to the 24th century.
Boss, if we don't make it to 4-20-2069, what happens to the Enterprise?

Well, you know, 4-20-2069 4:20 AM is really just a number and you can still keep it close to your heart.

The Enterprise will always continue to exist with the right captain at hand.
