constants inconsistency

[jmt]

From the manual (www.gnu.org/manual/blibc-2.2.5/html_node/CPU-Time.html) :

int CLK_TCK
        This is an obsolete name for CLOCKS_PER_SEC

But the following program :

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

int main(void)
{
        long int i=sysconf(_SC_CLK_TCK);
        printf("_SC_CLK_TCK    : %16d\n",i);
        printf("CLOCKS_PER_SEC : %16d\n",CLOCKS_PER_SEC);
        printf("CLK_TCK        : %16d\n",CLK_TCK);
        return 0;
}

running onn a Debian GNU/Linux reports :

_SC_CLK   _TCK :              100
CLOCKS_PER_SEC :          1000000
CLK_TCK        :              100

Using CLK_TCK gives correct results. Consequently, all examples in the manual 
using CLOCKS_PER_SEC return inconsistent results, while my programs using 
CLK_TCK give consistent results with the time function applied to them.

Is it a bug, or do I miss something ?
