| Feature | Description |
| --- | --- |
| [Time zone](/v1/docs/time-zones) | View the time zone where the contact center is located. This can be different than the time zone of the [User](/v1/docs/users-users) (agent, supervisor, admin, and so on). Contact Voiso Support Team to adjust this setting. |
