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().

Since Qt 5 8  we now have QDateTime  currentSecsSinceEpoch   to deliver the seconds directly  a k a  as real Unix timestamp  So  no need to divide the result by 1000 to get seconds anymore   Credits  also posted as comment to this answer  However  I think it is easier to find if it is a separate answer

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
