No time on Clock Free Throws

[yooperbballref]

Ok, I have seen this happen so many times and have asked multiple people on this and I can never get a straight answer. How is it possible for a player to shoot a free throw with the clock reading 0:00?Assuming the clock when an official blows the whistle, then logicly it should be impossible for there to be free throws with no time on the clock, but time and time again I see this happening.

To me, there is 2 options that an official can do it this situation.
1. Count the foul, and put time back on the clock (even if its just .2) before administering the free throws.
2 Say foul was after the horn and move on with the game, or post game handshakes.

Your thoughts....
