You cannot set the dimmers to different levels based on time of day if all you were using is direct association. It doesn’t allow you to do anything beyond “hit the switch, turn on the socket“. No restrictions.
(“Direct association“ has a very specific meaning on the SmartThings platform, and refers to a feature in the Z wave specification which allows one zwave device to talk to another Z wave device without having the messages go through the hub first . If you just mean you want a smart switch to be able to turn on a smart socket without running wires between them, that would be a different conversation. 
)
If you are using SmartThings to handle the communication between the switch and the socket Buy rounding the messages through the hub , rather than relying on zwave direct association, then you can have the restrictions, but that would be offtopic for this particular thread.
In either case we would need to know the exact brand and model numbers of the switch and the socket, unless you haven’t bought them yet.

I see you already asked this question in a different thread. I have answered you there.
