I assume the reason to be able to set/modify the published date is so
that you can enter content to be publsihed at a later date. Currently
this does not work and all content is published immediately.
The following will fix this for both entries and pages:
PageService.cfc findPublishedPages method, line 107 add:
arrayAppend(criteria, restrictions.lt("publishedDate", Now()) );
EntryService.cfc findPublishedEntries method, line 108 add:
arrayAppend(criteria, restrictions.lt("publishedDate", Now()) );
