Add TIMER for stream post (and other content) / shedule post [MOVED]

Hello. It would be great to allow user (or administrator) setup Timer to makes post (activity) publish later (not at the moment).

Screenshot with example like at vk.com. People also say it likes Facebook fans page post.

It can help adinistrator to spend 1 hour (per day) by creating posts, but makes it autopublished during the day.

Also it can be awailable and usefull for group's admins.

Thanks.
