Coordinated Universal Time, or UTC for short, is not a time zone. Instead, it’s a time standard. It’s based on the solar time at 0° longitude. Since the 0th longitudinal meridian is defined to be at the location of the Royal Observatory in Greenwich, England, UTC is sometimes also incorrectly referred to as GMT (Greenwich Mean Time).

UTC is the global standard for time and it is used extensively in the IT world. So just like it’s a global convention that the Prime Meridian is located in Greenwich, it’s a global convention to use the solar time of that same place as an international reference point.
