Personal Profile - Include Time Zone in the User Details section for sub users

Currently, the account time zone is only visible when logged into the primary account holder's user. Because there are a variety of features which are tied to the account timezone, it would be beneficial for all/certain users to have the ability to confirm/reference what this is set to. Allowing this to be displayed under the User Details section of the Personal Profile, as a read-only field, would be great!
