Thanks for explaining this, Jim. I was watching that game, and my family was asking what was happening, and I couldn't tell them. The clocks on the TV (shot and game) were clearly not exactly right. One question: The announcer kept saying that the shot left the player's hand before the shot clock hit 0. I thought the rule was it had to hit the rim before 0. Is this another stupid announcer thing, or is it another not-very-experienced-me thing? Also, isn't it true that the clock has another second to go AFTER the 0 shows on the shot clock -- because it doesn't show the tenths? And so, the horn or buzzer will be a full second after the 0 shows on the shot clock?

If the horn goes off while the shot's in the air then the
ball has to hit the rim or it's a violation, even if
the defense grabs the airball. If it hits the rim then we
reset the shot clock.

The buzzer should go off as the clock hits zero but it is
possible for the clock to be stopped with zero seconds
showing and no buzzer. I've never seen this happen
but it is in the case book. The buzzer signals the end
of time. But there is no 1 second lag between 0 on a clock
and the buzzer/horn going off, I guess it could be any
amount of time less than a second but there's no way
to easily tell.
