What's usually the timeline and when could we expect the docking?

Edit: Go it...

  Post-Launch Booster Recovery

  Okay, that's the routine stuff dealt with. I know we're all here 
  to see what happens to the first stage! Following stage separation 
  approximately 3 minutes into the launch, the first stage 
  will manoeuvre and orient itself to conduct a post-mission 
  landing test attempt on an autonomous drone ship named 
  "Of Course I Still Love You".

Since you edited with the first stage landing info, the expected landing is roughly T+9 min.

That name... it has Very Little Gravitas Indeed.
