Pods with TZ variable have wrong date after DST change in OpenShift 4

Issue

• Some Pods are not showing the right DST drift even if TZ variable is set to an appropriate timezone (it should be EEST in this example):

  $ oc describe deploymentconfig [dc_name] -n [namespace_name] | grep TZ
        TZ:               Africa/Cairo
  
  $ oc exec -n [namespace_name] [pod_name] -- date
  Wed May 17 10:44:06 EET 2023    <-- DOES NOT WORK, Africa/Cairo should have East European Summer Time (EEST) by May 17 2023
  

• Solutions How to set timezone for pods in OpenShift Container Platform? and Configuration of a Custom Time Zone for RHCOS Nodes did not resolve the issue.
