i’ve removed the two custom commands from my app.yml for now

```plaintext
## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"

  - exec: ln -fs /usr/share/zoneinfo/Europe/London /etc/localtime
  - exec: dpkg-reconfigure --frontend noninteractive tzdata

  - exec: echo "End of custom commands"

```

i never rebuilt with these custom commands present

i think it’s best not to specify a custom time for the container, it can just run on UTC while the host system runs on BST?

However, the removal removes the possibility of solving the below problem, with all-day events in @angus ‘s plugin

I don’t know what is the issue here, but for me just same works just fine.

```plaintext
  - exec: ln -fs /usr/share/zoneinfo/Europe/Helsinki /etc/localtime   
  - exec: dpkg-reconfigure --frontend noninteractive tzdata

```
