[trunk] report_sxw localcontext does not contain a parameter 'tz' required for the conversion time

class rml_parse(object):

# Convert datetime values to the expected client/context timezone
date = datetime_field.context_timestamp(self.cr, self.uid,
                                                        timestamp=date,
                                                        context=self.localcontext)

but self.localcontext['tz'] not exist
Namely, it influences the further conversion of time
