Real Time Clock

well the only way i have managed this time is in C but i am having trouble displaying it to the label

this is my code again

Code:

---

void __fastcall TForm1::lbTimeClick(TObject *Sender)
{
  lblTime->Caption = text;

  time_t now, last = time(&now), end = now + 10;
  while ( now < end )
  {
      if ( last < time(&now) )
      {
        char *text = ctime(&now), *newline = strchr(text, '\n');
        *newline = '\0';
        printf("\r&#37;s", text);
        fflush(stdout);
        last = now;
      }
  }
}

---

can you help understand why it is not displaying?
