There is now a convenient interface (in the "Edit a Saved Post" page) for rescheduling posts which have been scheduled to be published. It uses AJAX, so it requires Firefox 1.0.7, Internet Explorer 6, Safari 2.0.2, Opera 8.5 or other ECMA-262 compatible browsers.
There are still a few shortcomings in the interface, mostly as a result of some highly technical (and subtle) javascript execution-context details, and I hope to work them out soon. It shouldn't be a significant issue, though. Mostly it just means that the rescheduling won't get saved on the server if you close the rescheduling window too quickly. I'll eventually figured out a way around this, but it shouldn't be a problem for many people anyway.
