Using QTime in QML should produce a warning

Is there a reason QTime::currentTime() does not convert when handed to QML... like QDate and QDateTime do?

engine.rootContext()->setContextProperty("currentDate", QDate::currentDate()); // Can be accessed in QML as "currentDate"

engine.rootContext()->setContextProperty("currentDateTime", QDateTime::currentDateTime()); // Can be accessed in QML as "currentDateTime"

engine.rootContext()->setContextProperty("currentTime", QTime::currentTime()); // "currentTime" in QML is empty, needs to be QTime::currentTime().toString()
