End of game situation

[rfp]

Theoretical situation. Team A up by 1 point in the closing seconds of the game. Team B with the ball. Team B shoots and scores. Team A requests time out. Official blows whistle granting the time out. Immediately after the whistle sounds, the horn goes off signaling end of game. As the official, since you know your whistle beat the horn, can you put time back on the clock? If so, how much? To make it interesting, clock can only be set in 1-second intervals, no tenths. Discuss among yourselves, then I'll let you know what our interpreter said.
