Hi all!
I don’t think this is possible to set a certain time for a topic post to be pinned in the future (i.e. to choose a future date when the topic should be pinned) so I thought I would create this post for you to share your opinion. If this is already possible then please forgive me! 
Thanks!
Believe this may already be possible with: Discourse-automation
Just take a look at the screenshots in the OP …
Thanks a lot @merefield!
The idea is great and plugin can help in many ways but it seems the available scripts are very limited and so I’d need to install the plugin for just one script. (:
