@Gambit_1 Time zones follow lines of longitude because the Earth rotates on its axis, which creates a natural progression of time from east to west. The lines of longitude represent the divisions of the globe into 24 hours, with each hour corresponding to 15 degrees of longitude. This allows for a consistent and standardized way to divide time across the world. In contrast, using the lines created by sunrise and sunset would lead to constantly changing time zones that would be difficult to predict and manage. Additionally, the lines of longitude ensure that neighboring locations have similar time differences, which helps to facilitate communication, travel, and commerce between different regions.
