Time, Part Two (1940s)

The film discusses the concept of time zones and how they are essential for navigation. It explains that the Earth is divided into 24 time zones, each based on 15° of longitude, to maintain a standardized time system across different regions. The film illustrates how local times can differ significantly due to the Earth’s rotation, leading to different dates occurring simultaneously in various locations. It also covers the importance of the International Date Line and how crossing it affects the date without changing the time. Finally, it touches on the relationship between civil time, apparent time, and the equation of time, which are crucial for celestial navigation.
