WorldClock Integration does not allow viewing or changing time_zone

The problem

As of Core 2024.8.0 we are being told the WorldClock yaml configuration is being deprecated and settings have been migrated to the Worldclock Integration.

However, the Worldclock integration is severely lacking in its functionality. While setting a New Worldclock entry, you are able to Name it, set the timezone, and set the time format:

However, once created, you cannot change, or even view, the timezone. (So what is it? timezone, or time_zone? It's displayed two different ways in HA)

Apparently, the only way to change it is to delete and re-create, or edit it in ./storage/core.config.entries Which IMO is really a bad idea (and dangerous) and totally negates the purpose of a UI for this Integration.

I'm hoping this gets address before configuration.yaml / worldclock: integration is totally disabled in Core 2025.2.0, but IMO this should have been taken care of before a Deprecation Statement was issued.

Thank you.

Hey there @fabaff, mind taking a look at this issue as it has been labeled with an integration (worldclock) you are listed as a code owner for? Thanks!
