what is a leap second and why is it used
On 23 June 2015, when 23 clock 59 minutes and 59 seconds will be added to the World Clock, then a new second will be added to the world time and after that the total seconds of 2015 will be 31,536,001 crores. But why? What was the need like that and added only one second? After all, what if it is not added in a second and what does it have to do with the technological world. Let's know -
By the way, we are talking about the technical world, but before that we also know a little geography, you will be surprised to know that when there was a dinosaur period on Earth, the Earth used to take only 23 hours to take a round about on its circle. But now the speed of putting a circle on its circle of earth is slowing down. Its direct effect falls on time, the rotation speed of the earth is slowing down to equal to 2000th of a second.
Which makes a difference of about 15 seconds every 100 years. If leap seconds are not added this year, then in the coming 2000 years there will be a difference of one hour in Universal Time (UTC) and one rotation of the Earth on its axis.
To keep the atomic clocks in line with the Earth's orbit, additional seconds need to be added, or the clocks will go beyond the time of the solar system. This one extra second is called the leap second. The process of adding leap seconds has been going on since 1972. This will be the 26th time in 2015 when leap seconds will be added.
This leap second will be added on the night of June 30, although the total number of seconds in a day is 86,400, but after adding leap seconds, their number will be 86,401. With this, on the night of June 30, the clock will play 11:59:60, not directly 12 but 11:59:60.
There is no effect of leap seconds on your home computer, but many computers and website servers may crash. Google has already arranged this through leap smear technology. This technique works by merging this leap second in time. So that Google will not have to increase any second.
Leap Year
It takes 365 days 5 hours 48 minutes 45.51 seconds (about 365 days and 6 hours) for the Earth to complete one revolution of the Sun. This rotation of the Earth around the Sun is called the annual movement or rotation of the Earth.
The time it takes the Earth to complete one revolution of the Sun is called the Solar Year. Each solar year increases about 6 hours from the calendar year. Which is adjusted by making leap year every fourth year. The leap year is 366 days. Due to which there are 29 days in February instead of 28 days
Automatic Time
Atomic clocks are based on the vibrations of various radioactive materials and are said to calculate the purest time and make a difference of 1 second after about 30 million years, depending on different substances such as strontium. , Cesium etc. The Atomic Watch based in Switzerland is cesium based with a difference of 1 second in 30 million years.
