About UTC (Coordinated Universal Time)
UTC is the primary time standard by which the world regulates clocks and time. It is the basis for civil time around the world and is not adjusted for daylight saving time.
Time Format Explanations
Understanding Time Zones
Time zones are expressed as offsets from UTC. Your local time is automatically detected as UTC with an offset of +00:00 from UTC.
Why UTC Matters
- • Global Standard: Ensures consistent timekeeping worldwide
- • No DST: UTC never changes for daylight saving time
- • Aviation & Military: Uses UTC (Zulu time) for coordination
- • Computing: Standard for timestamps in databases and logs
- • Science: Required for astronomical and scientific measurements
UTC vs GMT
While often used interchangeably, GMT (Greenwich Mean Time) is an older standard based on solar time, while UTC is the modern standard based on atomic clocks. For most purposes, they are effectively the same.
