Why is it necessary to study time zones?
As Earth rotates, different parts of Earth receive sunlight or darkness, giving us day and night. As your location on Earth rotates into sunlight, you see the sun rise. Since different parts of Earth enter and exit daylight at different times, we need different time zones.
What is the most accurate time zone?
Time.is is synchronized with an atomic clock – the most accurate time source in the world. The displayed time will normally have a precision of 0.02-0.10 seconds. The precision depends on your internet connection and how busy your computer is.

Why do cities have different time zones for noon?
Each city and town defined its local noon – and effectively its local “time zone” – which is why so many older towns and cities have Clock towers in their “downtown” areas. The clock tower’s clock defined the “official” time in the town.
Why do time zones follow the boundaries of countries?
It is convenient for areas in close commercial or other communication to keep the same time, so time zones tend to follow the boundaries of countries and their subdivisions. Most of the time zones on land are offset from Coordinated Universal Time (UTC) by a whole number of hours (UTC−12 to UTC+14), but a few are offset by 30 or 45 minutes.
What is a ‘time zone?
A ‘Time Zone’ refers to any of 24 regions loosely divided by longitude, where the same standard time is kept. The Greenwich Meridian, also known as The Prime Meridian or International Meridian, or 0º longitude is the ‘ starting point ’ for dividing the Earth’s surface into time zones.
Should we get rid of time zones?
If we were smart, we’d get rid of time zones entirely. Most computers use UCT, and then they display it in whatever your local idea of the time szone happens to be, when you ask them to convert the number into a human readable form. To heck with time zones, to heck with “Daylight Savings Time”, etc..
