man 2 gettimeofday

That at least gives you microseconds, which you can convert to ms.

Or perhaps (not compile-tested):

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

Or some other equivalent.
