Setting timezone in kong pods

Hello,

is it possible to set the timezone in the kong pod (containers: proxy, ingress-controller) via values.yaml? (I want all pods in my namespace to use the same time zone as my local time zone).

I already tried setting customEnvs and volume mounts (see example below) but both versions failed.

customEnv:
  TZ: 'Europe/Berlin'
deployment:
  userDefinedVolumeMounts:
    - name: tz-config
      mountPath: /etc/localtime
  userDefinedVolumes:
    - name: tz-config
      hostPath:
        path: /usr/share/zoneinfo/Europe/Berlin

Any ideas and help is appreciated!
