AWS Workspace Timezone resetting after disable timezone redirection

Question

I've followed the documentation and disabled Timezone redirection (https://docs.aws.amazon.com/workspaces/latest/adminguide/group_policy.html#gp_time_zone).

We can now change the timezone on our Workspace instances, but the timezone change doesn't seem to persist (although it did on 2 instances).

I've changed the timezone on an instance to CST, then logging off and back on again the timezone is again at UTC.

Does anyone have any ideas on how to fix this?

Accepted Answer

Hi,

Just curious which WorkSpaces OS do you see this issues?
Do you know if this issue appears after a reboot of the WorkSpace as well or does it happen only on log on/off?
There's a couple of things you can check/try:

1. Check to see if the WorkSpace computer object in Active Directory located in an OU where the group policy is applied? If it's not, there's a possibility that the settings got reset after the reboot.

2. The work around described in the [documentation](https://docs.aws.amazon.com/workspaces/latest/adminguide/group_policy.html#gp_time_zone) suggests GPO configuration, however you can manually **try to delete the registry key** 
*HKEYLOCALMACHINE\SOFTWARE\Teradici\PCoIPAgent\ConsoleTimeZone*

Note: *I would recommend doing this on one specific workspace to test and doing so in a test environment if possible.*

3. Set the time zone using the UI or run **"[tzutil /s "Central Standard Time](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/tzutil)"** in the CMD

Note: *If you could also try to set the timezone during user logon using a logon script.*

4. Then reconnect to the Workspace to test.

Last, you should opens an **AWS Premium Support **case to continue troubleshooting of the issue.
