Answer to Question 1

Organizations store data in separate databases for several reasons. Given a choice, organizational departments prefer to control the data they use; they are, after all, the experts about the data. For example, accountants know more than anyone about how the accounting database should be used, so it is natural for them to want to control how it is set up, what the data will look like, and how the database will be updated. Also, a department may have very different objectives than other departments in the firm. These objectives might be to minimize inventory or serve customers. A department system that supports a key objective, even if it is an information silo, might be a better solution for the department than an enterprise system that doesn't support that objective as well.

Answer to Question 2

FALSE

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
