std::tm* localtime( const std::time_t* time ); 转换作为 std::time_t 值的从纪元起时间到以本地时间表达的日历时。 参数 time - 指向要转换的 time_t 对象的指针 返回值 成功时为指向内部静态 std::tm 对象的指针,否则为 NULL。该结构体可能在 std::gmtime、std::localtime 和std::ctime ...
您提到的"std"确实是C++标准库的命名空间,用于包含C++标准库中的大部分组件,如容器、算法、输入输出流等。 2. 解释"std::localtime"不存在的原因 在C++标准库中,localtime 函数实际上并不是定义在 std 命名空间下的。它来源于C语言的标准库,通常通过包含 <ctime> 头文件来使用,且位于全局命名空间中(...

The line in question isstd::tm* t_ = std::localtime(&t);. I think this is probably a longstanding warning that got turned into an error in VS2017. I tried to fix it but haven't gotten too far yet: Changing it intostd::localtime_sdoesn't work as that function doesn't exist ...
