When creating Discussions, it is possible to set the date and time availability of a forum. Unfortunately, it does not appear to be possible to make discussions available to different sections at different dates/times either from within the Discussions area or in Sections.
For workarounds, see the Module is Complete When section within the instructions outlining Modules: Controlling Content Availability via Modules noted below this section.
To Set Discussion Availability:

- Click Discussions in the course menu.
- Click on the Discussion you wish to edit.
Note: If you have not yet created a Discussion, click [+ Discussion] then jump to step 4 below. - Click [Edit] located at the top right.
- At the bottom of the page, set the Available From date.
- If applicable, set the Available Until date.
- Click [Save].
