How to get the current TimeStamp?

Question

I'm trying to get the current time as TimeStamp without success.

I have this code:

QDateTime setTime = QDateTime::fromString (QString("1970-07-18T14:15:09"), Qt::ISODate); QDateTime current = QDateTime::currentDateTime(); uint msecs = setTime.time().msecsTo(current.time());  return  QString::number(msecs); 

The output is

Sunday, January 25th 1970, 03:17:35 (GMT) 

Answer 1

In Qt 4.7, there is the QDateTime::currentMSecsSinceEpoch() static function, which does exactly what you need, without any intermediary steps. Hence I'd recommend that for projects using Qt 4.7 or newer.

Answer 2

I think you are looking for this function:

http://doc.qt.io/qt-5/qdatetime.html#toTime_t

uint QDateTime::toTime_t () const

Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).

On systems that do not support time zones, this function will behave as if local time were Qt::UTC.

See also setTime_t().
