Why does docker spin up containers with a timezone different than what I've set in Unraid, and how to I change the timezone in a container?

I set my Unraid to be PDT time.  I run the date command from the unraid console and it shows PDT time.  Great

But when I start a new docker app and open the docker container, its always on UTC time.  How do I change the time to PDT?  I tried adding a custom variable TZ with a value of America/Vancouver in the unraid application templates but it doesnt work.  The docker container remains UTC when I run the date command.

That will depend on the specific container.
