Bug in QIBASE (always returns 00:00:00.000 as time part of TIMESTAMP)

Ibase driver returns wrong value as time part of TIMESTAMP.

Issue reported in:
https://bugreports.qt-project.org/browse/QTBUG-29261

This patch (from https://bugreports.qt-project.org/browse/QTBUG-29261):
--------------------
static QDateTime fromTimeStamp(char *buffer)
{
static const QDate bd(1858, 11, 17);
QTime t(0, 0, 0);//########## should be fixed like this to pass on isValid()
QDate d;

// have to demangle the structure ourselves because isc_decode_time
// strips the msecs
t = t.addMSecs(int(((ISC_TIMESTAMP*)buffer)->timestamp_time / 10));
d = bd.addDays(int(((ISC_TIMESTAMP*)buffer)->timestamp_date));

return QDateTime(d, t);
}
--------------------

is fully correct.
