[未解决] 只接通电源,SD卡无法存储时间模块DS1307里的时机

       大佬们又是我,一直以来都麻烦大家啦!非常感谢大家无私的帮助。       我这里又遇到了一个问题,我这里的程序是想用SD卡记录两个传感器的数据和上传数据的时间,在电脑串口监视器里没有问题,此时SD卡的时间是现实的时间。但是,一旦编程用9V的电源供电的话,SD卡的时间就不正常了。附上我的程序,我把我用到的时间那部分标红,麻烦各位了

啥情况啊这是,真是要命了,希望大家不要嫌弃。
我一开始有拿书上的程序试过,但是上面那个tm.的函数告诉我不能用,我后来找库的时候看示例做了这个程序,虽然有点蠢,但是我之前在小屏幕上做了一个小时钟做测试,那个断电时间是不掉的
