Publication date?

[Joost Nelissen]

Hi,

Can anybody tell me if there's a good way to integrate a (future) publication date into a builder?
What i'd like to do is make it possible for a web-editor to specify a future date and time for publication without having to create a Time-object first and then make a relation to it.
Is there any documentation on this subject?

Thanks,
Joost Nelissen
