publishing future posts

A site I am building has a “schedule” section where the user can post the future events he will be attending to. For this I used post with a date set to the future.

The problem is that WP does not allow me to set those as “published” because it understands that I only want to publish those in the future (wich is not true).

How can I override this “future publishing” on my wp installation so it will always publish anything I set it to?

Thanks in advance.
ps. I am aware of plugins such as future calendar – that is not what I want to do.
