Feed publishing scheduled posts that are not yet live

[elanorpam]

I often create pages in advance and schedule them to be published in the future, but I've noticed that they tend to show up on my feed upon creation, rather than at their established publish dates. Even when they're not available in the website itself, they can be seen within the feed.

I can only assume it's taking the date created/edited into account, instead of the date published.
