                A UNIX timestamp of the topic's creation date (i.e. when it will be posted).
                Specifically, this value can only be set to a value in the future if the calling user has the `topics:schedule` privilege for the passed-in category.
                Otherwise, the current date and time are always assumed.
                In some scenarios (e.g. forum migrations), you may want to backdate topics and posts.
