可以调节分和小时（只能加），不知道在硬件上可不可以实现上电复位，反正在仿真的时候不行，所以设置了一个清零端
在这里附上我的报告（里面有详细的设计原理及过程）和原文件，还望大家指点，交流：
-It can adjust the hours and hours (only plus), do not know the hardware can achieve the power-on reset and, at any time in the simulation will not work, so set up a zero-side in my report is attached here (there are detailed design Principle and process) and the original document, we hope that pointing, exchange:
