I’m not sure if I understand your question correctly, but the clock in Docker containers is set to UTC. If you want them to use a different time you have to change their timezone settings.
This is from one of my images that I switch to time zone Zurich (modules not related to time zone deleted from the list):
Show us how you create your images and how you start your containers. It is not possible to give a general answer if we don’t know what you are doing.
