How do I change the rancher-server timezone settings?

[portfield-slash]

What kind of request is this (question/bug/enhancement/feature request):
question

Steps to reproduce (least amount of steps as possible):
I want to use kubernetes cronjob. My timezone setting is UTC+9.
I believe that it is necessary to change the timezone setting of the rancher-server container.
Is there any other good way?

Change the timezone of the underlying host?

@cjellick
Thank you for your comment.

I want to do it.
I changed the OS settings of the rancher-server container.
It confirmed that the OS settings were changed with the date command.

I then scheduled a cronjob, but Rancher's time settings didn't change.

+1. I have a scheduled job on my production cluster that is programmed like so : "0 6,12,18 * * *". Timezone is correctly set in the host node and i confirmed that with date command. But i noticed from workload logs that the job is executing at 8am, 2pm and 8pm everyday. Is there a timezone setting somewhere to configure in rancher cluster settings ?

[wisepotato]

also having this problem, because rancher is using UTC, anda ll docker containers that execute from it are UTC, but my server host is CEST

I also see this problem, host has the correct timezone set but rancher is off by 2 hours.

Edit cluster.yaml (Edit cluster > Edit as YAML) and add this lines to services section:

services:
    kube-controller:
      extra_binds:
        - '/etc/localtime:/etc/localtime'

After that configure correct timezone on Control Plane role nodes.
