[BUG] Time zone is not applied

[Blue20210921]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The time zone I set in docker-compose is not being applied.

I set the time zone in docker-compose as specified:

environment:
  - PUID=1000
  - PGID=1000
  - TZ=Europe/Berlin

But when I edit and save a page in DokuWiki, the time is always minus 2 hours.

docker exec -it dokuwiki date
Thu Sep 25 18:30:10 CEST 2025
docker exec -it dokuwiki php -r 'echo date("Y-m-d H:i:s T")."\n";'
2025-09-25 16:30:30 UTC

Expected Behavior

The time zone should be adopted and the time saved when editing the pages should correspond to my time zone.

Steps To Reproduce

Set up the container and set the time zone to Europe/Berlin.
Create or edit a page in Dokuwiki and save it.
Compare the time shown at the bottom right, when it was last edited, with the time in the Europe/Berlin time zone.

Environment

- OS: Debian 13

  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/debian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \

You can edit the php-local.ini in the config folder to set it. It only gets set the first time it's created. We don't modify it later. You likely created the container without the TZ var originally and it saved utc.
