According to discussion in https://support.okta.com/help/s/question/0D51Y00005pKGZCSA4/how-do-i-assign-a-timezone-to-a-user?language=en_US topic, it was stated:
"You can use any of the values from the TZ Database Name column from the Wiki link: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones...", but when I'm trying to create a user with `Europe/Kyiv` timezone (which is listed in TZ Database Name column) - I'm getting an error: "HTTP 400, Okta E0000001 (Api validation failed: timezone - timezone: For property 'timezone', string value of Europe/Kyiv is not a valid time zone), ErrorId oaep4Nv5zghQyCqzr-0uv6hag"
It fails to function through both Okta's UI new user creation and API integration:
Was the supported by Okta Timezone list changed? Or there is some bug in API validation logic?

Hello @j4l2b (j4l2b) Thank you for reacting out to our Community!
The information placed there is not correct, as that is not the supported format for Time Zone. The correct information it should be EEST. One you change that to EEST it should work without a problem.

Thanks @paul.stiniguta1.508386743840768E12 (Okta, Inc.) for the answer!
I'm curious if there is a comprehensive list of Time Zones supported by Okta that we can consult when creating users. Given the necessity to establish user profiles globally, the Time Zone field holds significant importance for our operations. Could you provide guidance or direct us to a resource where we can find the supported Time Zones for seamless user management?
The Url that you shared is correct, however in that particular field you can not use the name of the Country/City it has to be in the format EST, WEST, EEST, etc.
