Qstring 转换char*问题!

方法一:
QString qstr("hello,word");
const char * p = qstr.toLocal8Bit().data();
方法二:
const char *p = qstr.toStdString().data();
转换过来的是常量

把当前时间转化为QString...

public QDateTime qdate = QDateTime.currentDateTime();
datetime = qdate.toString("yyyy年MM月dd日ddddhh:mm:ss");
如果不是QTime和QDate类比如说：通过TCP/IP接收到的char    unsigned char 类等如何转换为QString类
QString Time2String( DWORD dwTime)
{
char cTime[50] = {0};
memset(cTime,0,50);
strftime(cTime,32,"%Y-%m-%d %H:%M:%S",localtime(&time_t(dwTime)));
return QString(cTime);
}
