looks like the gcc 2.95 from SL7.3 has a bug with implicit type conversions.
But you can workaround this problem with an explicit cast. Either make the
second argument of ?: a QString as well (QString("&nbsp;") or cast the 3rd
argument to a const char*. ((const char*) time2user...).

The other errors are of the same type.
