[udig-devel] Re: [Geoserver-devel] We're generating invalid dates in GML....

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.
