[support] Node created date vs latest revision date

Hi all, hoping for some help. I have a content type that is set by default to create a new revision each time a node is edited. This is because we have pretty liberal content editing permissions for many people, so we want to be sure changes can be reverted easily.

However, I just realized that in the node page and in Views, the "posted" date always uses the date of the last revision, instead of the date the node was created. So older articles that get a grammar fix are showing as newly created.

Is there a way to fix this? I've searched the forums, but haven't found an answer yet.

Thanks! Michelle
