Timing Error - NCAA-W - Clock stops during play

[jdw3018]

Question I should, but obviously don't, know the answer to. Last night in the Kansas State vs. Wyoming Women's NIT Semi game at the end of regulation WY was trying to score to tie. During a loose ball scrum, the clock stopped at 7.3 seconds for a couple seconds, then started again and WY made a shot close to the buzzer for the tie.

Officials conferred but nothing was changed and on to OT. My question - how to handle a stoppage of the clock like that if the officials become aware of it after time has expired. Could the officials use a stopwatch and monitor to determine how much time should have come off, compare that to when the shot went up and call the game if the shot wouldn't have counted?
