How to save XML timeformat to oracle without loosing "timezone-compensati"

Question

I hope i post this in the correct forum and I provide enough info for you to understand what I'm looking for...
Some time ago I got some help here about how to read a incoming XML-file and insert data into a table, where the Element-tag describes the tablename and the Attributes describes the column-names. See post : [ https://forums.oracle.com/forums/message.jspa?messageID=10284116#10284116]
During testing we discovered that on some incoming messages there where Date-fields, the date/time-values has the format '2012-04-19T14:00:05+02:00' which causing us problems when saving the value to our oracle table.
This is (simplifyed) how the message look like:
<?xml version="1.0" encoding="UTF-8"?>
<PickResult>
<Metadata>
<TransactionIdentity>"00000011"</TransactionIdentity>
<MessageTypeIdentity>"MyMessageType"</MessageTypeIdentity>
<MessagePartyIdentity>"02"</MessagePartyIdentity>
</Metadata>
<Data>
<PickResult PickingTime="2012-04-19T14:00:05+02:00" ProductDate="2012-04-20" Picker="MyEmployee" />
</Data>
</PickResult
I've tried different types on the PICKINGTIME-column like "DATE", "TIMESTAMP" and "TIMESTAMP(6) WITH LOCAL TIME ZONE" but I still get oracle errors like
"ORA-01858: a non-numeric character was found where a numeric was expected"
"ORA-01861: literal does not match format string"
when I run the statement.
If I declare the PICKINGTIME-column as "DATE" it works without errors but it doesn't add the two extra hours(+02:00) to the time which is very importent since the Picking time must be accurate.
This is the how the "final" Insert-statement look like which I need to modify somehow to make it accept the timeformat from the message:
INSERT INTO PickResult( PICKER, PICKINGTIME, PRODUCTDATE)
SELECT PICKER, PICKINGTIME, PRODUCTDATE
FROM XMLTable('/PickResult/Data/descendant::PickResult'
PASSING :1 COLUMNS
PICKER varchar2(35) path '@PICKER'
, PICKINGTIME date path '@PICKINGTIME'
, PRODUCTDATE date path '@PRODUCTDATE')
Can anyone provide me with some input how to solve this problem because I'm totally stucked...
ps. please forgive me for my poor "technical" english.

Hi,
PickingTime="2012-04-19T14:00:05+02:00"xs:dateTime format is mapped to TIMESTAMP (WITH TIME ZONE) in SQL.
This works for me :
SQL> select * from v$version;
