Sometimes it would be nice to be able to set a draft to be published when I'm not in front of the keyboard. Is this possible? If so, how?
See: Writing Posts (emphasis added):
To schedule a post for publication on a future time or date, click "Edit" in the Publish area next to the words "Publish immediately". You can also change the publish date to a date in the past to back-date posts. Change the settings to the desired time and date. You must also hit the "Publish" button when you have completed the post to publish at the desired time and date.
