Jestli jsou zajimave desetiny sekundy, pak nevim, jestli je shellovy
skript to prave. Nicmene potrebujete nasledujici program:

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

int
main()
{
  struct timeval tv;
  if (gettimeofday(&tv, NULL) < 0) { perror("gettimeofday"); return 1; }
  printf("%ld.%06ld\n", tv.tv_sec, tv.tv_usec);
  return 0;
}
