There is no consistency between regions as to when DST takes affect, or reverts back to standard real time. DST was never practical and will eventually be phased out obsolete. Standard Date Format Virtually the entire world formats time as Hours:Minutes:Seconds hours listed before minutes, minutes listed before seconds.
The date format Year-Month-Day has become widely accepted as a standard in many countries. For example:. Sign in. Sorted by time Sorted by type. New Zealand with exceptions and 5 more. Fiji, small region of Russia and 7 more. Japan, South Korea and 5 more. Although different regions in India had kept different time zones before, their time zones were unified during the colonial era to better manage the railway system. For better or worse, the unified time zone stuck, and Indians now observe the same time whether they live in Kmombai or Kolkata.
However, some countries that observe DST will switch to a different time zone for this purpose. On the other hand, plenty of countries around the world do not bother to switch back and forth to the DST. Converting Coordinated Universal Time to other time zones and adjusting it to your local time is nothing difficult. For this, you just need to understand the basic principles of time conversion. First of all, you should understand that the world is divided into 24 time zones. Still, Standard time is generally a whole number of hours from the UTC.
The worldwide standard time is based on the work of atomic clocks that are kept at various laboratories around the world to maintain the time. This means that they are in the GMT time zone.
Here are the countries that use standard time all year round:. Although there are no official figures, the number of people who live in the GMT time zone is in the hundreds of millions. However, keep in mind that many of these cities are not observing UTC time all year round because of Daylight Saving Time and other time zone adjustments. Here are the major cities that observe UTC at one time or another during the year:. In fact, Coordinated Universal Time is accompanied by some problems such as leap seconds or other issues.
Therefore, it offers useful information which can be rather limited sometimes. Leap seconds are important for UTC to get ahead of observable solar time. It is also known as "Z time" or "Zulu Time". To obtain your local time here in the United States, you need to subtract a certain number of hours from UTC depending on how many time zones you are away from Greenwich England.
The table below shows the standard difference from UTC time to local time.
