Preventing students from viewing future assingments

John_P490Hiding the channel does not make it invisible to students. Students will see the channel under 'Hidden channels' and can view the channel at any time from their channel list even if you set it as hidden by default. There is no way to set a date to change a hidden channel to 'Show'.
