Understanding Time Zones

The video tutorial explains how Earth's rotation affects time zones, using lines of longitude to mark each hour. It describes the day-night cycle and how time zones are politically influenced. A practical example is given to calculate time differences between New York and Denver, illustrating the concept of time zones and their impact on travel and jet lag.
