How to change the time zone of webmail clients
By default, webmail applications use the host server's time zone. Mochahost servers are based in Chicago, Illinois, under the UTC time zone.
If you are in a different time zone, you can change the settings of your webmail client. The exact steps to do this depend on the webmail application you are using. After you change the time zone setting, the interface displays timestamps in the new time zone the next time you log in to webmail.
Follow the appropriate procedure below to change the time zone setting for your preferred webmail application.
