For some people it is a natural feature, others understand it as the human brain activity. For mechanical engineering it is this movement; biologists say, that it is life; historians say, that it is death. Psychologists declare that time is consciousness. It is some kind of a natural phenomenon, generating all the changes in the world and it is not constant. Time is tangible and real. Time can be understood as a ratio of the material objects interaction. Yet we can (or can not) imagine that all things exist in the world forever, but our consciousness radius is narrow: that's what we capture and understand as "now". We do not have a conscious body all the time. The fact that we have a measure of time, does not mean that we understand the phenomenon. This is just an attempt to understand the nature of time, counting events.

Time traveler:Concept of time is obvious. Hours consist of a certain amount of minutes, days contains a certain amount of hours and a year consist of days. But people think about the fundamental nature of time rarely.
Time runs non-stop, and we follow the flow of clocks and calendars. However, it can not be examined under a microscope, it can not be researched directly. Everybody knows, that it exist. But nobody can see time, touch time an so on. And it still exists. We can not say what happens over time exactly. We can try to predict. Changes reflect time, for example, the rotation of the Moon around the Earth. Indeed, understanding of time is closely related to the concept of space. According to the general theory of relativity, space, or the universe, has begun about 13.7 billion years ago. It is called the Big Bang. Until then, all matter was packed onto very small point. That point was also the initial matter, which later changed to Sun, Earth and Moon. According them we calculate the time. Before the Big Bang there was neither time nor space.
So what is time now in the moon?

Guest:Why are time and clocks sio important for people?
There is no doubt time and clocks play a significant role in each person's life. I think no one has ever counted how many times approximately in 24 hours a man needs to know the time and looks at the clock. Working people since very morning have a look at the clock to find out if it is time to go to work. At work they also watch the time and look at the clock from time to time to know dinner time. The end of working day is so closely related to clocks as well. Speaking about leisure time it is impossible to ignore time and clocks. If we want not to be late to the cinema, theater or even shopping, time should be taken into consideration. Could we imagine our life without time and clocks in this fast moving world. It would be a huge chaos. On the whole, time and clocks are an inseparable part of our lives. Thus,let's cherish our time and use it sensibly, then we won't be sorry for wasting it in vain.

Difference between UTC and GMT is less than 1 second UTC = GMT = UT1 with precision 1 second
So in daily life they are EQUAL.
Coordinated Universal Time (UTC) is the time standard by which the world regulates clocks and time. Computer servers, online services and other entities that rely on having a universally accepted time use UTC for that purpose. UTC is a time standard based on International Atomic Time (TAI) with leap seconds added at irregular intervals to compensate for the Earth's slowing rotation. Leap seconds are used to allow UTC to closely track UT1, which is mean solar time at the Royal Observatory, Greenwich.
Greenwich Mean Time (GMT) is a term originally referring to mean solar time at the Royal Observatory in Greenwich, London. It is arguably the same as Coordinated Universal Time (UTC)
Universal Time (UT) is a timescale based on the rotation of the Earth. It is a modern continuation of Greenwich Mean Time (GMT), i.e., the mean solar time on the Prime Meridian at Greenwich, and GMT is sometimes used loosely as a synonym for UTC.
UT1 is the principal form of Universal Time. While conceptually it is mean solar time at 0° longitude, precise measurements of the Sun are difficult. Hence, it is computed from observations of distant quasars using long baseline interferometry, laser ranging of the Moon and artificial satellites, as well as the determination of GPS satellite orbits.
UTC replaced GMT as the basis for the main reference time scale or civil time in various regions on 1 January 1972. In casual use, when fractions of a second are not important, Greenwich Mean Time (GMT) can be considered equivalent to UTC or UT1. Saying "GMT" often implies either UTC or UT1 when used within informal or casual contexts. In technical contexts, usage of "GMT" is avoided; the unambiguous terminology "UTC" or "UT1" is preferred.
