Subject: [castor-dev] How to suppress TimeZone offset when Marshalling java.util.date







Hi All,



Does anyone know of a way to suppress timeZone offsets when marshalling a java.util.Date.



We unmarshall the following field



<dlx:FlightSegment DepartureDateTime="2005-06-04T11:45:00.000 "

ArrivalDateTime="2005-06-03T22:30:00.000+01:00" ResBookDesigCode="Y"

RPH="0" FlightNumber="9566" NumberInParty="1">



Then marshall back and the castor marshaller adds the daylight saving timezone offset of +01:00 to the

DepartureDateTime field.



<dlx:FlightSegment DepartureDateTime="2005-06-04T11:45:00.000+01:00 "

ArrivalDateTime="2005-06-03T22:30:00.000+01:00" ResBookDesigCode="Y"

RPH="0" FlightNumber="9566" NumberInParty="1">



This causes problems when we pass messages between machines in different timezones , as the marshaller

Adjusts the timezone accordingly and changes the time



Example below

> Request from time zone A:

> <dlx:FlightSegment DepartureDateTime="2005-06-04T11:45:00.000+01:00 "

> ArrivalDateTime="2005-06-03T22:30:00.000+01:00" ResBookDesigCode="Y"

> RPH="0" FlightNumber="9566" NumberInParty="1">



> Server Response from time zone B:

> <ns2:FlightSegment DepartureDateTime="2005-06-04T20:45:00.000+10:00 "

> ArrivalDateTime="2005-06-04T07:30:00.000+10:00" ResBookDesigCode="Y"

> RPH="0" FlightNumber="9566" NumberInParty="1">



DepartureDateTime ha s changed L



Any suggestions.?
