If date is valid and time is not, the time will

Returns a QDateTime object containing a datetime nmonths months later than the datetime of this object (or earlier if nmonths is negative). See also daysTo (), addDays (), addYears (), and addSecs ().

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.

Qt offers convenient classes for dealing with date/time values, but Qwt uses coordinate systems that are based on doubles. QwtDate offers methods to translate from QDateTime to double and v.v. A double is interpreted as the number of milliseconds since 1970-01-01T00:00:00 Universal Coordinated Time – also known as ”The Epoch”.
