Sqlite driver does not support milliseconds

Since QDate, QDateTime and QTime are converted to string, by using QVariant's toString(), in order to bind it to the sqlite3 context, milliseconds are ignored. I guess, QVariant::toString() uses the Qt::ISODate format.
QTime and QDateTime should be treated separatly and should be converted using yyyy-MM-ddThh:mm:ss.zzz or hh:mm:ss.zzz as format to cover the milliseconds.
