#102 timezone not supported for datatype "date"

[jmaroto]

As defined in http://www.w3.org/TR/xmlschema-2/#date, the date datatype can contain a timezone.

This is currently not supported by pyxb (from binding/datatypes.py):

class date (_PyXBDateOnly_base):

"""U{http://www.w3.org/TR/xmlschema-2/index.html#date}

This class uses the Python C{datetime.date} class as its
underlying representation.
"""

_ExpandedName = pyxb.namespace.XMLSchema.createExpandedName('date')
_Lexical_re = re.compile(_PyXBDateTime_base._DateTimePattern('%Y-%m-%d$'))
_Fields = ( 'year', 'month', 'day' )

Since datetime.date does not support timezones, fixing this will require changing the base Python representation for xsd:date to datetime.datetime.

On the topic of using datetime.datetime as the base Python representation, that's pretty much what JAXB does by default - it represents xsd:date as java.util.Calendar's (actually the XMLGregorianCalendar subclass), which is a datetime type with timezone support really.

Ok, I have an interoperability workaround for those trying to communicate with a JAXB implementation.

http://docs.oracle.com/javase/1.5.0/docs/api/javax/xml/datatype/DatatypeFactory.html#newXMLGregorianCalendarDate(int, int, int, int)

In converting to a XmlGregorianCalendar for an xsd:date, the fourth parameter can be set to DatatypeConstants.FIELD_UNDEFINED, which will stop JAXB from generating timezone data. Here's an example:

Calendar c = Calendar.getInstance();
test.setTestDate(DatatypeFactory.newInstance().newXMLGregorianCalendarDate(

c.get(Calendar.YEAR),
c.get(Calendar.MONTH) + 1,
c.get(Calendar.DAY_OF_MONTH),
DatatypeConstants.FIELD_UNDEFINED));
