UTC used to avoid confusion across what?

• A. Because it makes flights faster
• B. Because it avoids confusion over local time zones
• C. Because it aligns with local daylight saving
• D. Because it's a local standard

Answer: (B)

UTC provides a single, universal time reference worldwide. This keeps schedules, air traffic control, and records consistent when operations span many time zones, so everyone is literally on the same time regardless of location. It also avoids daylight saving complications, since UTC doesn’t change with seasons while local times may. So UTC is used to prevent confusion across local time zones. The idea that it makes flights faster isn’t related to time standards, and the notion of aligning with daylight saving isn’t accurate because UTC stays constant while local times may shift. UTC isn’t a local standard either—it’s a global reference.
