Coordinated Universal Time (UTC) is the world’s time standard. All time zones are defined as an offset from UTC, for example UTC+1 or UTC-5. UTC never changes for daylight saving time.
UTC is used in aviation, shipping, weather services, science and computer systems, and is often called Zulu time. For everyday use it is the same as Greenwich Mean Time (GMT).
