What is Coordinated Universal Time?
Coordinated Universal Time (UTC) is the primary globally recognized time standard that combines atomic time (TAI) and Earth rotation time (UT1) to ensure highly accurate time measurements. UTC ensures synchronization by introducing the leap second mechanism, which is periodically adjusted to bridge the gap between atomic time and Earth rotation time. This time standard is widely used in global communications, navigation systems, etc. to ensure time consistency between different systems and devices. In addition, UTC is also used as a benchmark for local time in various countries.
How many time zones are there in the world?
There are a total of 24 major time zones in the world, but the specific division of time zones is more complicated due to the actual needs and policies of each country. In fact, there are more than 38 different time zones in the world, as some countries and regions adopt time zones in half-hour or quarter-hour increments. In addition, there are places that adjust their time zones for daylight saving time.
