Kamenogorsk time. Ust-Kamenogorsk - exact time with seconds! The need for accurate time in modern life

Let me help you figure out what kind of animal this is. ;) Jet lag (otherwise known as jet lag) occurs when traveling long distances, during which you manage to change several time zones. Symptoms similar to fatigue:

  • insomnia or drowsiness;
  • headache;
  • migraine;
  • irritability;
  • possible problems with the gastrointestinal tract.

To tell the truth, waking up 3 hours earlier than usual is quite difficult, so for the first half of the day I was frankly nodding off and quite absent-minded. I don’t know whether I’m unwell, or whether the doctors haven’t tested their theories in practice... :)

However, you have a chance to smooth out such a sharp jump in time a little:

  • take a morning shower - it is wonderfully invigorating;
  • be sure to have a hearty breakfast;
  • drink less coffee (why do you need artificial stimulants?);
  • open the curtains in the morning because it's bright sunlight is a natural way to wake up the entire body;
  • spend maximum time in motion;
  • Don't get hung up on time. As practice has shown, it is better to look at the clock less often. ;)

In ancient times, knowing the exact time was not a daily need for humans. It was enough to determine the outcome of the day, and the main criterion for this was the position of the sun in the sky. The solar day begins exactly at noon, and this time is determined by the location of the shadows on the sundial. For many years and centuries, this method was the main one and was used to count days. But the development of society and technological progress inexorably began to require accurate knowledge of not only days, but also hours and minutes. After the sunny ones appeared hourglass, and now used to measure precise minutes during medical procedures and laboratory research, as well as tower, tabletop, wall-mounted, and wrist-mounted.

The need for accurate time in modern life.

Why do you need to know the exact time? IN modern world without this, the entire way of life would be disrupted, giving way to chaos and disorder. The transport system and industry would freeze, people would be late educational establishments and to work. Buses, trains and planes fly according to a schedule tied to an exact time. Modern financial relationships, which include such a word as “overdue,” cannot exist separately from exact hours, minutes and seconds.

Time Zones

The territory of the earth is so vast that in one part of the globe the sun sets, and at the same time in another place people wake up under the rays of the rising star. To organize geographic distances relative to precise time, scientists came up with time zones. The earth's surface is theoretically divided into 24 such zones: according to the number of hours in a day. The conventional band is approximately 15°, and within this interval the time differs by an hour from the time of the neighboring ones, +/-. The countdown is based on the Greenwich meridian and this time is called “Greenwich Time” (GMT). IN Lately began to use a more advanced reference system - Coordinated Universal Time (UTC).

Exact time online

IN Soviet times In Russia, the clock on the Spasskaya Tower of the Moscow Kremlin was the standard of time. They were the ones that were verified for accuracy, and all other clocks in the country, young and old, were measured against them. Today, the exact time with seconds can be found on specialized websites on the Internet, for which you just need to go to their pages. In this case, the exact time will change online, and you can easily navigate by time zones to find out what time it is this moment in Los Angeles, Moscow or Yekaterinburg.

Time and time zones

The length of an earthly day is determined by the time it takes the Earth to rotate around its axis, and is 24 hours. Local solar time corresponds to the apparent position of the Sun and is constantly changing due to the rotation of the Earth. When moving from west to east by 15° longitude, local solar time increases by 1 hour.

IN Everyday life official local time is used, which is different from solar time. The entire surface of the Earth is divided into time zones (in other terminology - time zones). Within the same time zone, the same time is used. The boundaries of time zones, as a rule, coincide with interstate or administrative boundaries. The time difference between adjacent time zones is usually one hour, although in some cases the time in adjacent time zones differs by two hours, 30 or 45 minutes.

For most countries in the world, the entire territory of the country is within the same time zone. The territory of countries that extend from west to east over a considerable distance, such as Russia, USA, Canada, Brazil and a number of others, is usually divided into several time zones. The exception is China, throughout which Beijing time is used.

The reference point for determining the time zone offset is Coordinated Universal Time or UTC. UTC corresponds to the mean solar time at the prime or Greenwich meridian. Time zone offsets relative to UTC range from UTC-12:00 to UTC+14:00.

Almost all countries in Europe and North America, as well as a number of other countries, move their clocks forward an hour in the spring, by summer time, and in the fall - an hour ago, to winter time. The offset of the respective time zones relative to UTC changes twice a year. In most countries of the world, the transition to summer and winter time is not practiced.
