[Feature]: EPG timezone offset

[admlko]

Is your feature request related to a problem?

My IPTV Service providers EPG is always one hour behind.
Some players supports setting offset for this and it fixes the issue (e.g. -60 minutes).

Describe the solution you'd like

Would it be possible to implement similar feature to Dispatcharr?
EPG offset can be positive or negative, and it would add or subtract x minutes from the EPG data.

Additional context

Compose:

  dispatcharr:
    image: ghcr.io/dispatcharr/dispatcharr:latest
    container_name: dispatcharr
    volumes:
      - ./dispatcharr/data:/data
    environment:
      TZ: Europe/Kyiv
      DISPATCHARR_ENV: aio
      REDIS_HOST: localhost
      CELERY_BROKER_URL: redis://localhost:6379/0
      DISPATCHARR_LOG_LEVEL: info
    group_add:
      - video
      - render # Uncomment if your GPU requires it
    devices:
      - /dev/dri:/dev/dri  # For Intel/AMD GPU acceleration (VA-API)
    restart: unless-stopped

I would like this feature to be on a per-channel basis. I have only one channel that seems to be 2 hours offset in the guide data, but all the other channels are fine.

I have several channels on one EPG that are 3 hours off. A per-channel offset via the UI would be amazing.

same here. i use open-epg for a few local channels but for some reason the offset i make on the web interface never reflects in dispatcharr and in turn a manual offset for a single channel epg would be great.
