One second.
Short answer: Yes, but a 2008 rule change allows the clock to restart on a referee's signal. This from the NCAA rules: Ball Out Of Bounds (Rule 3-2-5-a-12). When a ball is carried or fumbled out of bounds, the game clock will stop, as always. Beginning in 2008 the game clock will start on the referee's signal when the ball is ready for play, not on the snap. In the last two minutes of the half, however, the clock will start on the snap as before, preserving the ability of the offensive team to maximize strategic use of the clock.

"Three Hands of a Clock" (hour, minute and second hands).
Shot clock - the attacking team has 24 seconds to shoot on one attack. 3 second violation - when attacking players are in the key for more than 3 seconds 5 second rule - from the sideline or baseline, when the player with the ball does nothing for 5 seconds, e.g. pass. 8 second rule - when a player on the attacking team doesn't pass or shoot for 8 seconds.
The "clock" is a signal that turns on and off many, many times a second. For example, if your computer has a "speed" of 3 GHz, that means that the clock signal goes on and off that many times (i.e., 3,000,000,000) times a second. The clock signal is used to synchronize the different parts of the computer. As a general rule, a higher clock speed means a faster computer - however, the speed of the computer also depends on several other factors, including the number of processors, and whether it has enough RAM for the tasks it is supposed to do.
