你的程序有缺陷，給你改了一下，你試試。

void t0_server(void) interrupt 1
{
      TH0 = (65535-10000) / 256;
      TL0 = (65535-10000) % 256;
      ms++;
      if (ms >= 100)
      {
            ms = 0;
            s++;
            if (s >= 59)
            {
                     s = 0;
                     min++;
                     if (min >= 59)
      {
                              min = 0;
                              h++;
         }
                     if       (h >= 24)
                              h=0;
            }
      }
}
