Understanding Time Zones and Longitude

This video tutorial, presented by Tássia Reis, explains the concept of time zones, their relation to the Earth's rotation, and how they are calculated using longitude. It covers the role of the Greenwich Meridian as a reference point and provides practical examples to help viewers understand how to calculate time differences across various longitudes. The tutorial also includes complex scenarios involving time zone calculations for travel and communication across different regions.
