QDateTimeEdit and QTimeEdit wrong time specification when setting max time

Whenever the minimum time is set the time specification is assumed to coincide with the one set in the control (i.e. ignored), which is what is described for QDateTimeEdit::setDateTime. On the contrary when setting the max time, local time is assumed in all cases.

The relevant code is as follows for setMinimumTime:

void QDateTimeEdit::setMinimumTime(const QTime &min)
{
    Q_D(QDateTimeEdit);
    if (min.isValid()) {
        const QDateTime m(d->minimum.toDate(), min, d->spec);
        setMinimumDateTime(m);
    }
}

while for setMaximumTime:

void QDateTimeEdit::setMaximumTime(const QTime &max)
{
    Q_D(QDateTimeEdit);
    if (max.isValid()) {
        const QDateTime m(d->maximum.toDate(), max);
        setMaximumDateTime(m);
    }
}

Incidentally this makes QDateTimeEdit and QTimeEdit pretty finicky and quite frankly next to unusable in most real-world scenarios.
