DateTimePicker Confused about Epoch?

Something quite unusual is happening, it looks like the DateTimePicker in my app suddenly decided that epoch was three days later than it should be:

 

schedTimePicker = new DateTimePicker();

schedTimePicker->setMode(DateTimePickerMode::Timer);

connect(schedTimePicker, SIGNAL(valueChanged(QDateTime)), this, SLOT(onSchedTimeValueChanged(QDateTime)));

 

In the slot I have:

void MainClass:: onSchedTimeValueChanged(QDateTime time)

{

    fprintf(stderr, "%s:%d time=%s\n", __FUNCTION__, __LINE__, time.toString().toUtf8().constData());

}

 

When I set the time picker to 00:00:00 the output on the console is:

onSchedTimeValueChanged:5448 time=Sat Jan 3 00:00:00 1970

 

A full three days after actual epoch. Am I losing it? What's going on?

Re: DateTimePicker Confused about Epoch?

Apparently the parameter provided for the valueChanged slot is not what the documentation says it is.

 

The most reliable way of determining what the value changed _to_ when the slot is called is to look at the picker->value() value instead. I'm suspecting the parameter had the value that was previously set, or something along those lines.
