There's a time marker you missed and that Dalli_x missed because he still refuses to try more than one path.
The day Lana and Rox died, him and Buddy were talking about the Departed by Scorsese released in late 2006. Which means that the scene couldn't have happened before late 2006 at the earliest. We also know that Quinn was seven years old that night.
Considering she's one or two years older than than the main character in the current time, the events of the very episode first take place 13 or 14 years after the night when Lana and Rox died. So it's impossible than the first episodes take place in 2017-2019.
Unless the Departed was released sooner in DPC universe of course
