The clock starts when the Ball is ready for play.
That is usually called a 'spike'.

The center delivers the ball to the quarterback. center
Yes, because the play starts as soon as the ball is snapped.
In the huddle, the quarterback calls the play and at what count the play will be started. This information is not known by the opposing team. Therefore when he breaks the huddle, he calls the play and says on three. The center then knows to snap the ball on hut-3 and the other players know when to start moving. If they move before the ball is snapped, they are penalized yardage for movement before the snap.
Intentional grounding in football is when the quarterback throws the ball away to avoid a sack without a receiver nearby, resulting in a penalty. Spiking the ball is when the quarterback intentionally throws the ball into the ground to stop the clock, which is allowed in certain situations.

If this question is what I think it is, the quarterback kicks his knee to signal a receiver or another backfield player that he wants them to start in motion, before the ball is snapped.
yes, the quarter back spikes the ball so it can stop the clock so the team will have more time to run another play.
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.
Contrary to popular belief, the clock does not start when the ball is kicked-off. Rather, it starts when any player on the field touches it (after it was kicked). If the ball is kicked out of bounds (either across the sidelines or beyond the end zone), no time comes off the clock, because the clock does not start. In such a case, the clock would start when the first play is snapped fromscrimmage.
Encroachment is when a defensive player makes contact with an offensive player at the line of scrimmage prior to the ball being snapped. Unabated to the quarterback is when a defensive player charges across the line and is on his way to the quarterback before the ball is snapped.
