times function tested under GNU/Hurd, it always returns all zero in tms struct. PS: it's OK under GNU/Linux

time_test.c

#include <sys/times.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
  struct tms buf;
  if (times(&buf) < 0)
    exit(115);

  printf("utime: %u\n"
         "stime: %u\n"
         "cutime: %u\n"
         "cstime: %u\n",
         buf.tms_utime, buf.tms_stime, buf.tms_cutime, buf.tms_cstime);
  return 0;
}
