5-10-1: The referee may correct an obvious mistake by the timer to start or stop the clock properly only when he/she has definite information relative to the time involved. The exact time observed by the official may be placed on the clock.

Situation 6: Team A is trailing by three points when A2 attempts a three-point try at the end of the game. A2 releases the try and is fouled in the act of shooting. The whistle for the foul is followed immediately by the horn sounding and the clock at 0:00. The try is unsuccessful. Ruling: The officials are permitted to put time back on the game clock if there is definite knowledge of the correct time or information relative to the time that elapsed after the whistle blew and before the final horn sounded. If time is put back on the game clock, A2 will attempt three free throws with the lane spaces occupied. If the officials cannot determine the amount of time remaining or determine that there is no time remaining, A2 will attempt three free throws with the lane spaces cleared. (5-10-1; 8-1-3)
