On a straight forward inbounds play (full shot clock), are the officials trained to call the violation at 20 on the clock or 19?

I ask because the clock showing 20 can mean anything from 9.1 or 10 seconds have elapsed. 19 assures a full 10 seconds.

It was called near the end of the Maryland/Hawaii game with, I believe, 20 showing on the shot clock.
