Why can't I change my Site's time zone?
A Site's time zone affects all Jobs in the Site. Changing it could result in unexpected behavior for configured Jobs.
A Site’s time zone affects all of the Jobs in the Site, and there may be complex expectations encoded in the Job schedules. Copia does not allow changing a Site’s time zone to prevent confusing issues caused by shifting around the start time of all the Jobs in a Site.
