Subject RE: using timestamp with time zone
Date Wed, 02 Jan 2008 21:34:53 GMT
Some quick research on this indicated that this seems
to be a problem with the JDBC Timestamp API which does
not allow for the TimeZone part of the SQL data.  My
guess is that JDBC drivers for SQL servers that support
this column type convert this into the correct GMT 
time representation or supply a JDBC specific object
to support this.

Of course, this problem is compounded by the fact that
there is a LOT of variations of how different DB engines
(and version of them) support this column.

That said, there may be a couple of ways to deal with 
your problem in a local manner.

First, do you REALLY need that type of column?  Timezone
is really a display issue and not a storage one.  A date 
inserted into a DB Timestamp column using a Java Date object 
that has been created using Timezone parsing will be the
correct time if it is displayed with any associated TimeZone
setting.

If you really need this, then you might look at using a 
VARCHAR setting in the XML with the underlying DB manually
set to TIMESTAMP WITH TIMEZONE.  This should return your
JDBC's <ColumnObject>.toString() representation.  You can 
then locally override/add your own methods for converting 
too and from a Java date object via the String representation.
