You're right, but still, readability of the XML file has always been important
for KPA. So I think we really should stick to the ISO 8601 dates.

Please notice that any compatibility problem only can arise if you open your
db with a new version of KPA so that it's updated and then downgrade KPA
again.

And in this case, if we dot it like I would propose it, the only inconvenience
would be that the times may be displayed in UTC. I'm not sure about this
though, I didn't look at the displaying code yet. Even older versions of KPA
should correctly parse the newly added timezone.
