Unable to set timezone about sickgear.docker HOT 5 CLOSED

What are valid time zone values for the TZ variable?

Short answer, these, but at the bottom of the comment I include a better solution:

/opt/SickGear/lib/pytz/zoneinfo # ls -R

Long answer:
I took a look at the Dockerfile to look for timezone hints, searching it for 'tz' pointed me to these lines:

	&& export TMP=/tmp/sgtemp/ \
	&& mkdir -p ${TMP} \
	&& find ./lib/pytz/zoneinfo/ -maxdepth 1 -type f -exec cp -p '{}' ${TMP} \; \
	&& cp -rp ./lib/pytz/zoneinfo/Etc ${TMP} \
	&& rm -rf ./lib/pytz/zoneinfo/* \
	&& cp -rp ${TMP}* ./lib/pytz/zoneinfo/ \

Here it's copying a small subset of the possible timezones to a temporary folder (excluding the America/New_York I tried in the OP), wiping out the original full list of time zones, and then copying the shortened list back to the running directory. So that's the origin of the short list of time zones above.

Time to experiment. I spun up a test SickGear container, and added a volume mapping. I still have SickGear locally installed, and that folder has the full suite of time zones in it there. So I mapped that folder on top of the container's folder, and tried my desired time zone:

version: "3"
services:
  sickgear:
    container_name: sickgeartest
    image: sickgear/sickgear:latest
    environment:
      - APP_UID=1000
      - APP_GID=1000
      - TZ=America/New_York
    ports:
      - 8082:8081/tcp
    volumes:
      - C:\path\to\zoneinfo:/opt/SickGear/lib/pytz/zoneinfo

Huzzah, it booted and accepted the new time zone. I then copied the zoneinfo folder to my host's working folder for my actual SickGear docker container, and made the changes to my main SickGear docker compose file. It's working so far. So the better solution is:

1. Download this folder to your host's base folder for your SickGear container.
2. Add a volume mapping in your compose file or run command that maps the downloaded zoneinfo folder to /opt/SickGear/lib/pytz/zoneinfo
3. Set your TZ variable to the TZ identifier you need.

make sure your system has UTC and use it TZ=UTC

I don’t understand. The only acceptable time zone for that variable is UTC? I don’t live in the UTC time zone.

from sickgear.docker.

So UTC is Universal Time Coordinated , that is universal to all, including you.

Please set up like the docs say, there is nothing more I can advise as I am not a docker user. Perhaps someone in the community can help (I doubt it though). This docker has been running YEARS and no one has raised this issue.

So, if you cannot get the docker to work the way you like, then i recommend you run the normal app, which is mature.

Warning, there are unexpected results from your suggestion. Though the bundled third party pytz library has other timezones, UTC is the only one supported in the application. For example, trigger times for certain operations may produce unexpected results. Good luck though.
