Time Server Application▲
The Time Server Application instantiates a MinuteTimer object and shares it with all connected Time Client Applications.
I. Defining Remote Objects using a REP-file▲
The REP-file "timemodel.rep" in the parent directory of the example is used to generate the header-files used by both applications. For this application, the generated "rep_timemodel_source.h" file defines MinuteTimerSource, the the class to subclass for the implementation of MinuteTimer, and other related classes.
II. The TimeModel Class▲
The TimeModel class in timemodel.h and timemodel.cpp implements the time object to share. It uses a QBasicTimer to ensure that the time is updated by calling the timerEvent member function.

void MinuteTimer::timerEvent(QTimerEvent *)
{
QTime now = QTime::currentTime();
if (now.second() == 59 && now.minute() == time.minute() && now.hour() == time.hour()) {
// just missed time tick over, force it, wait extra 0.5 seconds
time = time.addSecs(60);
timer.start(60500, this);
} else {
time = now;
timer.start(60000-time.second()*1000, this);
}
qDebug()<<"Time"<<time;
setHour(time.hour());
setMinute(time.minute());
emit timeChanged();
