What to know about UTC

UTC never changes for daylight saving. That makes it the safest way to record an exact moment, but people still experience meetings in their local city time.

Pilots and the military often call it Zulu time and write a trailing Z, as in 14:00Z. ISO 8601 timestamps use the same Z suffix.

UTC is kept within a second of astronomical time by occasional leap seconds. For everyday conversion, UTC and GMT give the same clock reading.
