Last week I noticed that the pod in Argo would give a UTC timezone even though the Argo configuration has set a AEDT timezone.

apiVersion: argoproj.io/v1alpha1
kind: CronWorkflow
metadata:
  name: my-cron-workflow
  namespace: MYNAMESPACE
spec:
  schedule: "0 10 * * *"
  timezone: "Australia/Sydney"

Actually, this timezone in configuration is only used to give the time this scheduled job would run at, not the timezone in every pod.

To set up a unified timezone for all the pods, we need to use volume.

apiVersion: v1
kind: Pod
metadata:
  name: busybox-sleep
spec:
  containers:
  - name: busybox
    image: busybox
    args:
    - sleep
    - "1000000"
    volumeMounts:
    - name: tz-config
      mountPath: /etc/localtime
  volumes:
    - name: tz-config
      hostPath:
        path: /usr/share/zoneinfo/Australia/Sydney
        type: File
