From the screenshot sent, you'd like the AP to broadcast everyday only from 1:00 PM to 2:00 PM. When you configured this from GUI did you click on OK >> Exit >> OK again >> Commit and Save?
SSH into the AP and run the following commands:
>en
#conf t
#wlan wlan1
#show context | include time
What do you see in regards to time based access?
You should see this:
time-based-access days all start 13:00 end 14:00
What is the model of the AP?
Which firmware version is it on?
