Description

Replace hardcoded TZ=Europe/Amsterdam values with TZ=${TZ} in the Paperless, Picard, and Posterizarr Compose configurations. This makes each stack honor the timezone configured in its .env file and aligns these services with the repository template.

Paperless-specific PAPERLESS_TIME_ZONE configuration is unchanged.

Related Issues

  • None.

Verification

  • docker compose config --quiet in services/paperless
  • docker compose config --quiet in services/picard
  • docker compose config --quiet in services/posterizarr
  • git diff --check origin/main...HEAD

Checklist

  • I have performed a self-review of my code and followed the templates structure.
  • I have added verification that the stack works as expected.
  • I have reviewed documentation requirements; no documentation changes are needed for this configuration fix.
  • A maintainer needs to select the appropriate label because external contributors cannot apply upstream labels.

Additional Context

  • None.

* All services: align the TZ setting with the service template

The service template defines TZ=Europe/Amsterdam in .env with a link to
the list of time zones, and passes it on as TZ=${TZ}. A few services
did not follow it.

- Dockge, NewWallpaperWhoDis, Radicale: add the TZ block to .env.
- Open WebUI, Tandoor, RustDesk Server: use the template comment on the
  TZ line.
- Gramps Web, Mealie: read TZ from .env instead of a fixed
  Europe/Amsterdam in compose.yaml.

Paperless, Picard, and Posterizarr have the same fixed value. #329
already fixes those.

* All services: pass TZ to a container only when its image uses it

Every .env defines TZ, but 31 app containers never received it, and a
few received it without using it. Each image was started with
TZ=Asia/Tokyo to see whether a process inside reports Japan time.

Add TZ=${TZ} to the app container of 28 services whose image uses it:
Arcane, Booklore, Coder, ConvertX, copyparty, Dockge, Dockhand, Docmost,
Dozzle, EspoCRM, FossFLOW, Glance, Gotify, Homepage, Memos, Miniflux,
NewWallpaperWhoDis, NextExplorer, Portracker, Radicale, Speedtest
Tracker, Stirling PDF, Sure, Technitium, Tracktor, Uptime Kuma,
Vaultwarden, XWiki.

Remove it from 5 services whose image has no time zone data and logs in
UTC regardless: Beszel Hub, Homebox, Navidrome, Portainer, RustDesk
Server.

TZ stays in every .env file.
