Since I very often publish in the future, I have this problem a lot.

The date that gets given to the RSS feeders, is the date a post actualy gets created.
But if it is published in the future, I don't want that dae, but indeed the date that the post gets published.

Creating a post and directly put in the correct date gives me what I want.
But sometimes I create a post in 'draft' and I'm not shure yet what date the post has to go public, than the date is irrecoverble (besides when going to phpmyadmin)

This is not a bug but a tedious unplesant side-effect.
