Answer 1

这个比较简单的哦，我给你讲步骤吧，
第一步，创建一个dateTimeEdit，第二步，将其connect到一个函数上，第三部，提取它的QDateTime,然后利用下面的函数就可以了，它是基于shell命令的：
void moreidDialog::slot_save_time_key()
{
QDateTime time;
QString str = txt_time->text();
//判断格式是否正确
if (str.count(".") != 4)
{
txt_time->setText(tr("ge shi cuo wu"));
return;
}
int i = 0,j = 0;
i = str.indexOf(".");
QString year = str.mid(0,i);
j = str.indexOf(".",i + 1);
QString month = str.mid(i + 1,j - i - 1);
i = j;
j = str.indexOf(".",i + 1);
QString day = str.mid(i + 1,j - i - 1);
i = j;
j = str.indexOf(".",i + 1);
QString hour = str.mid(i + 1,j - i - 1);
i = j;
j = str.indexOf(".",i + 1);
QString min = str.mid(i + 1,j - i - 1);
bool ok = false;
year.toInt(&ok);
if (ok == false)
{
txt_time->setText(tr("ge shi cuo wu"));
return;
}
month.toInt(&ok);
if (ok == false)
{
txt_time->setText(tr("ge shi cuo wu"));
return;
}
day.toInt(&ok);
if (ok == false)
{
txt_time->setText(tr("ge shi cuo wu"));
return;
}
hour.toInt(&ok);
if (ok == false)
{
txt_time->setText(tr("ge shi cuo wu"));
return;
}
min.toInt(&ok);
if (ok == false)
{
txt_time->setText(tr("ge shi cuo wu"));
return;
}
str = "date -s " + month + "/" + day + "/" + year;
system(str.toLatin1().data());
str = "date -s " + hour + ":" + min + ":" + "00";
system(str.toLatin1().data());
//强制写入到CMOS
system("clock -w");
}

Answer 2

QDateTimeEdit *dateTimeEdit = new QDateTimeEdit( QDateTime::currentDateTime(), this );
在看看QDateTime类是怎么设置时间的就行了
