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. Sunny day originate exactly at noon, and this time is determined by the location of the shadows on sundial. For many years and for centuries this method was the main one and was used to count days. But the development of society and technical progress inexorably began to demand exact knowledge not only of days, but also of hours and minutes. After the sunny ones appeared hourglass, and are now used to measure precise minutes during medical procedures and laboratory research, as well as tower, table, wall, wrist.
The need for accurate time in modern life.
Why you need to know exact time? IN modern world without this, the entire way of life would be disrupted, giving way to chaos and disorder. They would freeze transport system and industry, people would be late in educational institutions 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 “delay”, cannot exist separately from accurate clock, minutes and seconds.
Time zones
The territory of the earth is so vast that in one part globe the sun sets, and at the same time in another place people wake up under the rays of the rising star. To organize geographical distances Regarding the exact 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 standard of time was the clock on the Spasskaya Tower of the Moscow Kremlin. 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 at the moment in Los Angeles, Moscow or Yekaterinburg.

Ekaterinburg, Russia - general information
The length of an earthly day is determined by the time it takes the Earth to rotate around its axis, and is 24 hours. A consequence of the rotation of the Earth is both the change of day and night, and the fact that when moving from west to east by 15° longitude, the local solar time, determined by the apparent position of the Sun, increases by 1 hour.
IN everyday life official is used local time, which differs to a greater or lesser extent from the solar one. 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 are determined by considerations of convenience and, 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 or more hours. There is also a time shift of 30 or 45 minutes.
For most countries, the entire territory of the country is within the same time zone. The territory of countries extending from west to east over a considerable distance, such as Russia , USA , Canada , Brazil and a number of others, 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 in time 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 Europe And North America, as well as a number of other countries, move their clocks forward an hour in the spring, to summer time, and in the fall - an hour back, to winter time. The offset of the respective time zones relative to UTC changes twice a year. However, most countries in the world do not practice this clock change.
