Resetting Clock()???

Ok, i have my code:

Code:

int seconds;
	clock_t clock();
	seconds = clock()/CLOCKS_PER_SEC;
 
	if (seconds == 8){
			FIVE.SetPositionX(-1);
			}
//....
if ((AdventureGame.keypressed[DIK_F]) && (WOO.positionX == -10)){
 
		//reset clock() here
		FIVE.SetPositionX(-5);
}

the clock starts when the program is run and after 8 secs, FIVE moves position.
When i press F, i want FIVE to reset its position [which it does], and to reset the clock(), so that after 8 secs, FIVE will move again.
Anyway to do this?
Using Windows 7, visual studio

You can't reset the clock(), so you should use another variable to save the old value, then compare that to the latest.
