CalendarSerializer dateTime bug?

[Pa...@swisscom.com]

Hi all

I tried to serialize a dateTime where I have a Calendar with date
"0001-01-01"
When Axis serializes it would use UTC. All ok. 
As im located central europe my date is CET and it creates the UTC -1
Hour.

Now I get the value:   "0001-12-31T23:00:00.000Z" 
Should it not add additionally the sign "-" in front of, so that I would
receive "-0001-12-31T23:00:00.000Z"?

The problem is in deserialisation where I get the date "0002-01-01".

XSD-Type in WSDL
<complexType name="DateRange">
	<attribute name="start" type="dateTime" use="required"/>
	<attribute name="end" type="dateTime" use="required"/>
</complexType>


Using Axis 1.2.1 (but same behavior in higher versions, see
CalendarSerializer in CVS).
The DateSerializer checks with an internal calendar for BC or AD, but I
do not understand how
there the calendar should go BC..., perhaps when the computer time is
BC?

Should the CalendarSerializer not check the value (should be a
java.util.Calendar) if it is
BC or AD and add a "-"?

Thanks
Patrick
