How do I set up swarmpit agent timzone?

When I tried to easily install swarmpit with docker, the timezone-related argument did not exist, so I manually specified it in docker-compose, but the swarmpit agent did not set the timezone. How can I set the swarmpit agent timezone?

My docker-compose.yml
