To find the time zone in hours of a particular location, you can take the longitude — in degrees — and divide it by 15. So, for example, 75° E would be 75/15 which equals 5. That translates to the time zone being 5 hours ahead of UTC or GMT time, which can also be labeled as UTC+5.
Moreover, how do timezones work?
There are 24 hours in a day, and 360 degrees of longitude encompassing the globe – dividing 360 by 24 gives you the 15 degrees of longitude that equates to a one-hour difference in each time zone. Based on this, you can then deduce that there are 24 time zones around the world.
To convert 18:00 UTC (6:00 p.m.) into your local time, subtract 6 hours, to get 12 noon CST. During daylight saving (summer) time, you would only subtract 5 hours, so 18:00 UTC would convert to 1:00 p.m CDT. Note that the U.S. uses a 12-hour format with a.m. and p.m.
Secondly, how was time established?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
