When we upgraded to 1.9 the trust level 4 users seem to have lost their ability to set timers for topics. So they cannot auto-close topics or close them temporarily. They can close them in a regular manner, though.
This must be a bug or a regression. It cannot be intentional, right?
(We are on 1.9.1)
Possibly, what do you think @tgxworld?

Trust level 4 had the feature in 1.8. No doubt about it.
Did it work though? When I tested this back in August the timer didn’t actually do anything when it was triggered:

We never experienced any problems. Here is a topic that was scheduled to close in 60 minutes by a TL4 user:
那我算是彻底糊涂了。把这个议题移回 #contribute:bug。我先保持安静，等真正的工程师（@tgxworld）来了再让他看看这个

@jomaxro Yea topic timers are supposed to be available to admins and users with trust level 4 or higher. Do you recall why we restricted it to staff only?

It came from this topic: Scheduling topics for future publication. Topic timers were not working for TL4 users when I tested it (timers could be set but nothing would happen when they triggered), so Jeff said to disable it unless it was an easy fix.
Ah icic. I’ll have a look then 
Can you try reproducing this again? I tried locally but the timers were working fine for me. Thank you!
In the mean time, I’ve reverted
https://github.com/discourse/discourse/commit/5a57a454fe713080814736442a6feb4863ec8c70
I can confirm that auto-close, close temporarily, auto-open, open temporarily, schedule publishing, and remind me all work for a TL4 user on try.
However, Auto-Delete does not appear to work.
TL4 users cannot delete topics anyway, couldn’t you just remove auto delete for TL4 since that is the only problem.
This is now fixed by @zogstrip
