Daylight Savings Time01 On Sunday, November 5, 2017, at 2 a.m., most of the United States will reset their clocks one hour to officially end Daylight Savings Time.
We have an hour’s sleep!
Residents of Arizona, Hawaii, the American territories of Puerto Rico and the Virgin Islands will not take part in the festivities.
According to, the third largest company in the world, about 75 countries participate in the summer time program.

Bad news?
We lose this hour on the 11th. March 2018. It’s only a matter of time
Mr. Early to bed, early to get up, Benjamin Franklin attributed the idea to summertime, but in 1784 nobody really thought of it. More than a century later, in 1895, George Vernon Hudson reintroduced the concept to give him more time for his hobby, collecting insects after work.
You’ve got to be kidding me!

During the First World War, both parties took advantage of the idea to reduce electricity consumption in Europe, in particular the consumption of incandescent light bulbs. In 1966, the Uniform Time Act of the United States of America decided that the clock should be set at a later date on the last Sunday in April and at a later date on the last Sunday in October. Over the years, the rules of the DST have changed… This law was amended in 1986 so that summer time begins on the first Sunday in April, although the new system was not introduced until 1987. However, the expiry date of the TNG was not changed and remained the last Sunday from October to 2006.

Today summer time begins on the second Sunday in March and ends on the first Sunday in November. While some people (spring clocks*) change their clocks exactly 2 hours at night, the simplest spring clock goes one hour forward just before bedtime. Take your time and do it right!
*I just made that up.

Bad news?
We lose this hour on the 12th. March 2017.

Brief History of Time
(which has almost nothing to do with Stephen Hawking’s book of the same name),
Chronometry is the science of measuring time or time registration. By the time you have finished reading this document, you will be an expert in this field. Well, not right away, but you will.
Just in time.

The Egyptians were the first to create a day and a night; ten o’clock during the day, ten o’clock at night, and two periods of twilight in between. Shadow clocks were used to track time throughout the day; and they used large obelisks to follow the movement of the sun.
The Egyptians are often credited with making shadow clocks, but the Chinese, Babylonians, Greeks and Romans used such instruments to determine time. Because a large shadow is no more accurate than a small one, sundials have become the norm for most civilizations. Does anyone really know what time it is?
Was the sundial very accurate? Of course, about once a year, for a few short minutes. The inclination of the earth’s axis, the seasonal variations in the sun’s rotation, and even the day the sundial was brought into use, all had an influence on the time displayed (and still displayed). For best results, in the northern hemisphere, the edge of the shadow is generally aligned so that it runs north and is parallel to the earth’s axis of rotation.
A gnomon is the part of a sundial that casts a shadow over the numerals or time stamps on the ground. The most famous is probably the gnomon of Saint-Sulpice in the church of Saint-Sulpice in Paris, which was used by the Da Vinci Code as a rose line in the novel.
Does anyone really care? Is this a good time?

It just got better and better.
The oldest known water clock was built in the 3rd century. Century v. Chr. in ancient Greece. Why water? This is mainly due to the fact that some people had to know when it was time to go to sleep and that the sundials did not work at night (they still did not work in many parts of the world).

How do I set up a water meter?
Take a large bucket and fill it with water up to a certain line. Then cut a small hole in the bottom of the bucket and mark the lines on the bucket after every hour of the day using the obelisk or the sundial as a guide.

The Chinese started using mercury more accurately about a thousand years ago, around the same time the Arabs started using equipment and weights. Sand in a sealed hourglass can also be accurate, at least enough to measure the time it takes to draw an alligator in a batch of Pictionary.

Late 14th century. At the end of the 19th century, mechanical watches in Europe made use of the so-called boundary-crossing mechanism. Basically, measured by weight and acceleration, they were very large and were the first bells to ring.

Spring watches and pocket watches appeared in the 19th century, and Galileo’s invention of the pendulum in 1602 gave the movement an unprecedented sequence and became the measure of timekeeping until electricity further perfected the clock’s accuracy. The pendulum clock can be accurate up to one second per year.

Quartz electric generators were developed in the 20th century. Centuries and atomic clocks invented in the 1940s. In the UK, the NPL-CSF2 is now accurate to the second every 138 million years.

The smallness of time
– 15 degrees of longitude describes the time of day.
– Although Russia is geographically spread over 12 time zones, it officially covers only 9 time zones.
– Greenwich Mean Time is the starting point for world clocks. GMT is also known as UTC – Coordinated Universal Time. Greenwich is at 0° longitude and was officially recognized at the International Meridian Conference in 1884.
– Time has been described as the fourth dimension. The other three are length, width and depth (or height).
– The land and weather were exhibited on the evening of Saturday the 22nd. October 4004 v. Chr. Chr., according to James Asher, archbishop of Arma in the 17th century. It originated at the end of the 18th century, in the footsteps of the Bible.
– The Earth slows down, about 55 billion seconds a year.
– Time is the most commonly used name in English.
– Do you recycle a lot? In 2012 these calendars can be used exactly -1804 1832 1860 1888 1928 1958 1956 1984.
– The nanosecond is the time it takes to move with a light foot.
– The nanosecond is a billionth of a second.
– The picosecond is a billionth of a second.
– A femtosecond is a quadrillion second.
– An attosecond is a five billionth of a second.
– In a typical year of 365 days, you have five hundred and twenty-five thousand six hundred minutes.
– This means we have 31,536,000 seconds a year.
– Time passes quickly and heals all wounds, they say.
– Einstein’s special theory of relativity claims that because of the speed of light, two witnesses of the event will not necessarily see the event at the same time. Time is usually relative to the observer. So we can see a star in the sky that shone millions of years ago, that might have been (or was) dark – light needs time to move.
Is it possible to travel faster than the speed of light? NO. Why is that? Because Albert Einstein said so.
– Joe’s theory of relative time is the effect of slowly waiting for something special, or when you’re working while you know your friends are having fun. True, on the contrary, you are laboriously longer than the fleeting time that your friends enjoy or that will be your special event.

Early warning :
Monday and Tuesday, after the clock had gone up an hour in March, is associated with a 10% increase in the risk of heart attack, said UAB Assistant Professor Martin Young, PhD in Cardiovascular Diseases. The opposite happens when you fall in October. This risk is reduced by approximately 10%.

Yang’s making an offer:
On Saturday and Sunday you get up 30 minutes early to prepare for an early start on Monday. Eat a decent breakfast. Go into the sun early in the morning. Lessons in the morning at the weekend (provided that you have had no previous heart disease).
All this will be both the central or workshop clock in the brain, which responds to changes in light-dark cycles, and the peripheral clock – the one that can be found everywhere, including in the heart – which responds to food consumption and physical activity. In this way, your body can naturally synchronize with changes in the environment, which can reduce the risk of negative health problems on Monday.

From time to time it is our duty to remind you to replace the batteries in the fire alarm when you go back!
