Milliseconds from QDateTime

[scamE]

Hi, all
I have code:

#include <QtGui/QApplication>
#include <QHBoxLayout>
#include <QLabel>
#include <QDateTime>
#include <QString>
#include <time.h>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QWidget* w =new QWidget;
    QHBoxLayout* lyaout = new QHBoxLayout;
    QLabel* label;
    time_t seconds;
 
    QDateTime* date_f = new QDateTime;
    QString milisec;
    QString format="mmssz";
    QString & need_f=format;
    seconds=time(NULL);
    date_f->setTime_t(seconds);
    milisec=date_f->toString(need_f);
 
    label = new QLabel(milisec);
    lyaout->addWidget(label);
 
    w->setWindowTitle("Try again");
    w->setLayout(lyaout);
    w->show();
 
    return a.exec();
}

#include <QtGui/QApplication>
#include <QHBoxLayout>
#include <QLabel>
#include <QDateTime>
#include <QString>
#include <time.h>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QWidget* w =new QWidget;
    QHBoxLayout* lyaout = new QHBoxLayout;
    QLabel* label;
    time_t seconds;

    QDateTime* date_f = new QDateTime;
    QString milisec;
    QString format="mmssz";
    QString & need_f=format;
    seconds=time(NULL);
    date_f->setTime_t(seconds);
    milisec=date_f->toString(need_f);
 
    label = new QLabel(milisec);
    lyaout->addWidget(label);

    w->setWindowTitle("Try again");
    w->setLayout(lyaout);
    w->show();

    return a.exec();
}

date_f->setTime_t(seconds) don't return time in milliseconds.
Why is? What method can return time in milliseconds?

Thanks.

Miliseconds will always be zero here because time() has a resolution of one second.

I thought about it. Ok, what function can return time with milliseconds?
My OS is Linux.

Try QDateTime::currentDateTime().
