[Request] List chapter date published on story index

In v1.1, I had modified the story index to list when each chapter was published, so users who might not have been back for a while have some idea of when the story was updated, chapter by chapter.

I tried modifying the storyindexblock myself, but i noticed that just putting the {published} code in doesn't actually pull the date from the table when generating the story index, so I'm assuming at this point some PHP code needs to be altered somewhere. 

Could someone possibly provide me with what code hacks/changes need to be made to allow the publish date for each chapter to be included?

Thanks,
