Answer to Question 1

Answer to Question 2

The semimajor axis, a, is half of the longest diameter. The eccentricity, e, of an ellipse is half the distance between the foci divided by the semimajor axis. The eccentricity of an ellipse tells you its shape; if e is nearly equal to one, the ellipse is very elongated. If e is closer to zero, the ellipse is more circular.

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.
