body: <pre><code>int main()
  {
      time_t ltime;
      time( &amp;ltime );
      tm *    pTm = localtime(&amp;ltime);
      while(true)
      {
          for(int i=0;i&lt;1000;i++)
          {
              if(i==999)
              {
                  printf("Program time is: %02d:%02d:%02d \r", pTm-&gt;tm_hour, pTm-&gt;tm_min, pTm-&gt;tm_sec);
                  i=0;
              }
          }
