Qt获取当前时间

QDateTime current_date_time = QDateTime::currentDateTime();
QString current_date = current_date_time.toString("yyyy-MM-dd hh:mm::ss.zzz");

QTime current_time = QTime::currentTime();
int hour = current_time.hour();        //当前的小时
int minute = current_time.minute();    //当前的分
int second = current_time.second();    //当前的秒
int msec = current_time.msec();        //当前的毫秒

SYSTEMTIME sys;
GetLocalTime(&sys);
printf("%4d/%2d/%2d %2d:%2d:%2d.%3d\n",sys.wYear, sys.wMonth, sys.wDay, sys.wHour, sys.wMinute, sys.wSecond, sys.wMilliseconds);
