About Coordinated Universal Time
Coordinated Universal Time is used in aviation, the internet, weather services and science as the world's reference clock. UTC never changes for daylight saving, and every other time zone is written as an offset from it.
Daylight saving time
Coordinated Universal Time is UTC+0 all year. It does not change for daylight saving time, so its gap to places that do switch, like New York or London, changes by an hour twice a year.
