The UI container does not have the tzdata package.

• image: registry.opensource.zalan.do/acid/postgres-operator-ui:v1.10.1
• run in: Bare Metal K8s
• No. We haven't launched it into production yet, but we want to do it.
• The tzdata package is not installed in the image and the TZ env does not work.

The time in the interface is displayed in UTC and the time cannot be changed because the container does not have the tzdata package.

The report identifies the postgres-operator-ui:v1.10.1 image and provides a kubectl exec reproduction, but no repository file or image-build entry point. Start by locating the build definition for that UI image and reproduce the TZ/date behavior; done means the image includes timezone data and TZ=Europe/Moscow is reflected by the container's date output.
