Change post date without publish_posts

Is it possible to change the post date without the publish_posts capability?

We don’t want our authors to be able to publish content (limited wordpress know-how and an in-house content approval process – their posts must first be approved by an editor). However, this means when they create a post, they cannot specify a date (as we have removed the publish_posts capability). Ideally we would like them to somehow be able to define a post date as this date would also be displayed in our editoral calendar (Edit Flow Plugin).

Is there a way to allow the definition of a post date without the publish_posts capability?

Thanks.
