[EKS] [Feature Request]: Enable to change EKS cluster timezone

**Tell us about your request**
Enable to change EKS cluster timezone

**Which service(s) is this request for?**
EKS

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
I manage a product deployed on-premise k8s cluster contains some cronjobs, and all servers run on JST. Now I try to run it on AWS with EKS and would like to use the same k8s manifest YAML.
AFAIK EKS cluster timezone cannot be changed from UTC, so it wouldn't be done.

**Are you currently working around this issue?**
Have two k8s manifests per a cronjob.

Review the EKS request alongside the existing Kubernetes CronJob manifests, focusing on how timezone-dependent schedules currently differ between on-premise and EKS deployments. Done would mean EKS supports the requested timezone behavior and the same CronJob manifest can be used without maintaining a second timezone-specific manifest.
