When viewing these hours under "Hour of Day", are they displayed in server time (UTC)? If the workspace has a Time Zone applied to it, do the hours update to display in the converted time?

Hello Ian, GoodData displays your data in your organization in the time zone of the server. This means, that if you filter your data to This day, GoodData displays the same data for all workspaces and users, even if they are located in a different time zone. To enable users to display the data in their local time zones, you can configure a specific time zone for your organization, workspace, or even for individual users. GoodData then converts the data to the time zone that the user has configured.
