c++中time.h函数报错：应输入声明，缺少函数标题(是否老式的形式表?)

Question

问题遇到的现象和发生背景

调试代码发现time.h文件竟然报了25个错误，这个不是系统文件吗，为什么有错，而且错误都集中在AppCRT Time Function片段中

问题相关代码，请勿粘贴截图

运行结果及报错内容

错误(活动) E0169 应输入声明 CalPennPartCS C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\ucrt\time.h 131
警告 C4003 类函数宏的调用“throw”参数不足 CalPennPartCS C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\ucrt\time.h 135
错误 C2447 “{”: 缺少函数标题(是否是老式的形式表?) CalPennPartCS C:\Program Files (x86)\Windows Kits\10\Include\10.0.18362.0\ucrt\time.h 135

我的解答思路和尝试过的方法

按照网上提供的方法，把time.h的编码格式调成UTF-8，或者UTF-8-BOM都不行

我想要达到的结果

请求各位指点

错误跟time本身无关，就像你说的，库函数本身是没问题的。有问题的是你使用库函数的代码，所以还是把你的代码贴出来看看吧
