Answer 2

Long ago in a country not too far away, the Royal Astronomer in Greenwich England was the astronomer to the King. At the time Great Britain was the greatest power in the world (remember at one time they said "the sun never sets on Great Britain because they had most of the world under the british flag). When they started making maps, they needed a starting point, so they pick the Observatory in Greenwich as the zero point of longitude, and all distances were measured east or west from that point. Since England ruled the world, english time was accepted, so this is where we get Greenwich Mean Time. The average time since time is relative as to how you measure it. Since there are 24 hours in a complete day, 360 degrees in a complete circle (earth) every 15 degrees was an hours difference.  So Eastern standard time is 75 degrees west of Greenwich, england so we are (those who live in EST) 5 hours behind GMT. So 1 pm is 6 pm GMT. HOWEVER - since modern timekeeping has come into play, they no longer use GMT. Since science is more precise with the time keeping they use Universal Coordinated time, cause the time is constantly updated by the measuring of the Cesium Atom molecules.

So if you are in the USA, there are 4 time zones, - 5 hours on the eastern coast, minus 8 hours on the western. Daylight savings time you are 4 and seven. You do now have first hand experience as to why the world's major factors use  GMT, or ZULU or Universal Coordinated time.
