1、用CTime类 先用time_t类型构造一个CTime对象，再定义一个SYSTEMTIME结构，最后用CTime类的成员函数GetAsSystemTime将时间转换到SYSTEMTIME结构中即可。2、用gmtime函数 gmtime函数将time_t时间转换到tm结构中并返回一个tm指针，再将tm结构的相对应的项赋给SYSTEMTIME相对应的项即可，不过用这种方法要注意...
@文心快码BaiduComatetime_t转systemtime 文心快码BaiduComate 在C++中,将time_t类型转换为SYSTEMTIME类型通常涉及几个步骤。time_t类型通常表示自1970年1月1日(称为UNIX纪元或Epoch)以来的秒数,而SYSTEMTIME是Windows API中定义的一个结构体,用于表示日期和时间。以下是一个详细的步骤和代码示例,展示如何将time_t...
