My experience runs contrary to what you seem to have been told.

I've had my KTN entered into my PNRs at 45 minutes to 23 hours ahead of scheduled departure and gotten PreCheck LLL nearly always in such circumstances when flying a PreCheck-enabled carrier from a PreCheck-enabled US terminal/airport on trips originating from the US. Often enough I've had this (add KTN within less than 24 hours to departure) work even after I've already been checked in for the flight.
