This question has been answered by lkfranklin. See the first response.
The Published On date (the publishedon field in the database) is actually just a record of when the resource last changed from unpublished to published. The Published On field is set automatically when the resource changes from unpublished to published. This happens when either someone checks the "Published" checkbox and saves it, or the Publish On date is reached and the resource is published automatically.

As of 1.1 you can change the importx.processor system setting from "create" to "update" to update resources based on the ID you pass along with the query. If the resource can't be find it will be created.https://docs.modx.com/extras/revo/importx
