2022 Time Zones - UTC
The graph above shows that there is no clock change in UTC during 2022.
What Is UTC?
UTC—Coordinated Universal Time—is the 24-hour time standard used as a basis for civil time today. All time zones are defined by their offset from UTC. The offset is expressed as either UTC- or UTC+ and the number of hours and minutes.
Primarily, UTC is based on mean solar time at the prime meridian running through Greenwich, UK. For every 15 degrees of longitude east or west, mean solar time changes by 1 hour. Two time components are added together to translate mean solar time to Coordinated Universal Time (UTC): International Atomic Time (TAI) measured by atomic clocks and Universal Time (UT1), the actual length of a day on Earth.
In theory, the UTC offsets countries use should reflect the local mean solar time. However, many time zone boundaries are distorted by geographical and political factors.
No Daylight Saving Time in UTC
Daylight Saving Time (DST) is not used for UTC as it is a time standard for all time zones.
