Fix JDBC type of TIMESTAMP WITH TIME ZONE

Currently the JDBC type of TIMESTAMP WITH TIME ZONE is Types.OTHER.
JDBC 4.2 has a dedicated type for this Types.TIMESTAMP_WITH_TIMEZONE.

Unfortunately this type is only available in JDBC 4.2/Java 1.8 so I
hard code the constant value instead of the constant reference.
