Understanding Time Zones and Longitude

This video tutorial explores the concept of time differences based on Earth's rotation and longitude. It explains how the Earth rotates 360 degrees in 24 hours, equating to 15 degrees per hour or 1 degree every 4 minutes. The video discusses the theoretical calculation of time differences between locations based on longitude, using examples from Auckland, Wollongong, San Francisco, and New York. It highlights the difference between theoretical calculations and real-world time zones, providing practical examples to illustrate these concepts.
