You don't need PCC for PNP.
You need PCC for Express Entry ITA.
In India, you have to schedule PCC appointment and it takes around 10-15 days afterwards.
You will get 60 days after ITA to accept it and submit documents.
Mine changed to assessment around 58-59 days and not 28 days.
It depends on application to application and different officers. Each case is different.
Check with people near your timelines (near your AOR date).
Good luck :)
