C++如何获取当前时间并转换成相应的格式字符串

wchar_t* pNewFolder = new wchar_t[30];  
__time64_t long_time;        
struct tm newtime;

_time64( &long_time ); 
errno_t err;
err = _localtime64_s( &newtime, &long_time ); 
if (err)
{
    WSLogEx(L"Invalid Arguments for _wctime_s. Error Code: %d/n", err);
}
wcsftime(pNewFolder,30,L"%Y%m%d%H%M%S",&newtime);
