What is GMT and why is it important?
Greenwich Mean Time (GMT) is the time at the Royal Observatory in Greenwich, London, and serves as the world's time standard. It's important because:
- Global Reference: Provides a universal time reference for international coordination
- No Daylight Saving: Remains consistent year-round, unlike local times
- API Standards: Used in web apis, database and scheduling systems like DaySchedule to generate appointment time slots
What is the difference between GMT and UTC?
While both are often used interchangeably, there are subtle differences:
- GMT (Greenwich Mean Time): Based on Earth's rotation, historically used as the world standard
- UTC (Coordinated Universal Time): Based on atomic clocks, more precise than GMT
Our tool displays both formats to ensure compatibility with different systems.
