time.h function clock() only returning 0

[Brian Bober]

I was testing whether clock skew between gettimeofday and between clock() still
occurred, and I noticed now that clock() returns 0 only.

Sample code output:

[boberb at netdragon1 gettimeofday]$ ./clock
0
0

Sample code:

/* clocktest.cpp */
#include <time.h>
#include <iostream>

int main(void)
{
    std::cout<<clock()<<std::endl;
    sleep(1);
    std::cout<<clock()<<std::endl;
    return 0;
}
