Hmmm... I thought we had at least modified toString to at least give consistent output, but it looks like that is not the case.
There's this DateUtil class in the codebase: http://svn.geotools.org/geotools/branches/2.3.x/module/main/src/org/geotools/feature/type/DateUtil.java
That handles W3C dates and times, but it appears we're not using it in the code at all.
It sounds like we should fix either the encoder or the toString to do a bit better than it does now.

Hmmm, I am surprised the wfs 1.0 cite tests pass as they do a lot of

so that makes sense.

Hmm... that's suprising nonetheless... attributes encoding in Geotools
FeatureTranslator is handled in FeatureTranslator.handleAttribute:

if (Geometry.class.isAssignableFrom(value.getClass())) {
     geometryTranslator.encode((Geometry) value, srsName);
} else {
     String text = value.toString();
     contentHandler.characters(text.toCharArray(), 0,
         text.length());
}

Sooo.... it seems to me it was working only because of sheer luck? :-)

Looking at the FeatureTypeEncoder, every subclass of java.util.Date
will be turned into a xs:datetime, so I guess wfs 1.0 passed only
because we use Postgis as the backing store, which was configured
to use a date type, and returned as a result a java.sql.Date that
toStrings to something which is in the format CCYY-MM-dd, apparently
another format supported by xs:datetime.

Cheers
Andrea
