setTimestamp Time Zone Ignored in ServerPreparedStatement (no replies)

As mentioned in http://bugs.mysql.com/bug.php?id=15604 there have been several bugs concerning time zones which should be fixed using the new code by setting useLegacyDatetimeCode=false.

One of the issues that has been fixed for the PreparedStatement is that now the time zone of the Calendar specified by the setTimestamp(int parameterIndex, java.sql.Timestamp x, Calendar cal) call is used to format the given Timestamp.

Why is this not the case for the ServerPreparedStatement?
The corresponding method setTimestampInternal(int parameterIndex, java.sql.Timestamp x, Calendar targetCalendar, TimeZone tz, boolean rollForward) simply ignores the given time zone tz if the legacy code is switched off.

Is this a bug?
