Issue Summary

RSS feed Published Date, Updated Date and "dc:date" changes with each update

Steps to Reproduce

1. Create a blog post and publish it.
2. Create an RSS feed with Feed Builder to only use this space, sort by created, limit to 5 items from the last 500 days (advanced options).
3. Generate RSS feed url: note "published" and "updated" and "dc:date" are the same recent timestamp, as they should.
4. Edit the newly created blogpost and click "Update".
5. Refresh the RSS feed url after a few seconds.

Expected Results

"Updated" timestamp is updated to a few seconds ago.
"Published" and "dc:date" remains the same as the time when the Blogpost was created first time.

Actual Results

"Updated", "Published" and "dc:date" are updated to the same timestamp from a few seconds ago.
