clock and timing.

[Tom Davids]

I've just coded up this small program

#include <stdio.h>
#include <time.h>

main(){
clock_t start, stop, total;
int count;

start = clock();
printf("%d\n", CLOCKS_PER_SEC);
for(count=0; count < 200000; count++);
stop = clock();
total=stop-start;
printf("total = %lu\n", total);

}                    

The CLOCKS_PER_SEC is 1000000,
When I run the program I get the either
total = 10000
total = 20000
or
total = 0.

Could someone explain what the numbers range so much when the CLOCKS_PER_SEC is so high.
Any help is highly apprieciated.
Thanks
