Found the NCAA ruling for you, Tony.

2008-09 NCAA Men's & Women's Basketball Casebook, page 16.

A.R. 33. There are 37 seconds (men) or 32 seconds (women) on the
game clock and 35 seconds (men) or 30 seconds (women) on
the shot clock. Team A uses time before A1 releases the ball for
a try for goal. After A1 releases the ball, the shot-clock horn
sounds. The ball does not strike the ring or flange. The officials
call a shot-clock violation. At the same time as the official’s
whistle, the game clock sounds, signaling that the period has
ended. Shall the official put two seconds back on the game
clock?
RULING: No. The shot-clock horn sounded at the expiration of the
shot-clock period; however, this does not stop play unless recognized by the official’s whistle. The official’s whistle for the shot-clock violation stopped play. The expiration of playing time was indicated by the timer’s signal. This signal shall terminate player activity (Rule 2-10.14). The period ended with the violation. However, in games
with a 10th-of-a-second game clock display and an official courtside
television monitor, when in the judgment of the official time has
elapsed from when he or she signaled for the clock to be stopped to
when the game clock stopped, the monitor may be used to determine
the correct time to be put back on the game clock. In games without
an official courtside television monitor, the official is required to have
definite information relative to the time involved to correct the time
elapsed.
