Hi,

first you should go to api.kde.org instead of developer.kde.org. The 
documentation you were looking at was "Generated on Fri Oct 6 00:29:29 2006"

Regarding your question: the current API is not meant for any exact timings 
(which is also impossible with xine at least). But if close to 3000ms/8000ms 
is good enough for you you can do the following:

m_media = new MediaObject;
AudioOutput *out = new AudioOutput(Phonon::MusicCategory, m_media);
Phonon::createPath(m_media, out);
m_media->setCurrentSource(...);
m_media->pause();
m_media->seek(3000);
m_media->play();
m_media->setTickInterval(100);
connect(m_media, SIGNAL(tick(qint64)), SLOT(tick(qint64)));

.
.
.

void tick(qint64 position)
{
  if (position > 7900) {
    m_media->stop();
  }
}
