Set Europe/London timezone in pipeline-visualiser container

[AP-Hunt]

What problem does this pull request solve?

Trello card: https://trello.com/c/gg3J5mMT/434-visualiser-fix-timezone

The timezone needs to be set explicitly to Europe/London in order to show the correct time in tool. Ruby respects the timezone information when it's present, and automatically converts timestamps with a timezone attached into the local time.

How to review

1. Go to CodePipeline in an AWS account and find the date a pipeline last ran. Make a note of the time and timezone.
2. Run the tool locally in a container

cd support/pipeline-visualiser/
docker build . -t forms-pipeline-visualizer:latest

CREDS_JSON="$$(aws sts assume-role --role-arn "arn:aws:iam::711966560482:role/deploy-pipeline-visualiser-ecs-task" --role-session-name "run-pipeline-visualiser")"; \
AWS_ACCESS_KEY_ID="$$(echo "$${CREDS_JSON}" | jq -r '.Credentials.AccessKeyId')" \
AWS_SECRET_ACCESS_KEY="$$(echo "$${CREDS_JSON}" | jq -r '.Credentials.SecretAccessKey')" \
AWS_SESSION_TOKEN="$$(echo "$${CREDS_JSON}" | jq -r '.Credentials.SessionToken')" \
\
docker run -p "4567:4567" -e "TZ=Europe/London" -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN -e AWS_REGION -v "$$(pwd):/app" forms-pipeline-visualizer:latest

3. Open it up, find the pipeline you were looking at in the AWS console
4. Check the time noted there matches what it should be in Europe/London

Reminders

If you've made changes to the deployer role (files in modules/deployer-access):

• Remember to run make <environment> forms/account apply on the relevant environments (dev, staging, user-research, and/or prod)
• Check the #govuk-forms-deployment-notifications Slack channel to ensure the apply-forms-terraform-<environment> pipelines have run successfully

Is there a way we could get it to show the timezone based on the browser locale?

[AP-Hunt]

I dunno, I'll have a look into it!

I've addressed it with a little bit of JS to reformat the dates into local time. I couldn't see that HTTP requests send client timezone information with them, so it wasn't possible to do server side.
