The Need for a Universal Time System
Before a standardized system existed, every region used local solar time, which caused confusion when railways and international travel developed.
To solve this problem, the world adopted a universal time reference.
Today, that system is Coordinated Universal Time.
Why UTC Is Used Worldwide
UTC allows global systems to operate smoothly.
It is used by:
airlines
military operations
satellite navigation
internet servers
global financial markets
By using UTC as a reference point, countries can coordinate schedules and communication across time zones.
