0 seconds on the clock, Stop the game?

For NCAA the period ends with the red LED lights, if they are present and working, or the horn sounding if no lights.
However, when judging whether a try for goal shall count or not using the monitor, the game clock showing zero has #1 priority, then the LED lights, and finally the horn.
Now I also believe that the same would apply to deciding whether or not a foul took place prior to end of a period. Is that true?

First of all, if there is no replay equipment none of what we're discussing applies. These rules only apply when an official is reviewing the play on official replay equipment.

That said, 2-5-2 tells all. To your question:

2-5-2.f. Ascertain whether a foul, at or near the expiration of time that will determine the outcome of the game (win, lose, tie), occurred before the reading of 0.00 on the game clock.

1. When it is determined that the foul occurred before the reading of 0.00 on the game clock, the official is permitted to put the exact time back on the clock as to when that foul was committed.

Note: An on-screen graphic display on the monitor may be used only when the display is synchronized with the official game clock.

A.R. 11. At or near the expiration of time, A1 is fouled in the act of shooting and then after the foul releases the ball for a try for goal. A1’s try is (a) successful (b) unsuccessful.

RULING: When a foul and a try for goal sequentially occur at or near the expiration of time, the official shall use the monitor to determine whether the foul and the try occurred before the reading of 0.00 on the game clock. In (a), when it is determined that the foul occurred before the reading of 0.00 on the game clock but the try was not released before the reading of 0.00, the foul shall be penalized and the goal shall not count. When it can be determined with the use of the monitor, the official shall be permitted to put the exact time on the game clock as to when the foul occurred. When it is determined with the use of the monitor, that both the foul and the try occurred before the reading of 0.00 on the game clock, the foul shall be penalized and the goal shall count. When it can be determined, with the use of the monitor, the official shall be permitted to put the exact time on the game clock as to when the foul occurred. When this determination cannot be made, the official shall be permitted to put the exact time back on the game clock when it can be determined as to when the ball passed through the net. In (b), since the try was unsuccessful, the official shall use the monitor to determine whether the foul occurred before the reading of 0.00 on the game clock. When it is determined that the foul occurred before the reading of 0.00, the foul shall be penalized. When it can be determined, the officials shall be permitted to put back on the game clock the exact time as to when the foul occurred.
