上述代码可正常运行,无需调设置。
运行环境:VS2017的Windows控制台应用程序。
最后附上CTime类在头文件中的定义(非自定义)。
class CTime
{
public:

#ifdef _AFX
CArchive& Serialize64(_In_ CArchive& ar);
#endif
private:
__time64_t m_time;
};
注意:GetDayOfWeek()这个函数是从周日开始算起,即周一为2。
将读取到的时间转化成CString类型。
#include

#include
using namespace::std;
int main()
{
CTime today = CTime::GetCurrentTime();
CString tt ;
cout << today.GetYear() << "-" << today.GetMonth() << "-" << today.GetDay() << endl;
tt.Format( "%d-%d-%d",today.GetYear(),today.GetMonth(),today.GetDay());
cout << tt << endl;
return 0;
}
注意:需要将项目属性中的字符集设置为多字节字符集或者不设置字符集,不能使用Unicode字符集,否则Format函数不能正常调用。
