Drupal creates log entries for certain events, and sends messages on behalf of the site, such as notifications of new content to subscribed users, login instructions for users receiving new accounts, and so on. The server itself might be located in one time zone, and may host several sites. The date and time on the computer might not necessarily be the same as that of the organization to which the site belongs. The location and time zone entered here are used to ensure that the log entries and communiques use the correct time.
