If you enter multiple city names, select a continental preset. UT and world time zones. It' easy to know what time it is in your classroom right now - just look at the clock. The entries can be sorted by city or country.

## time zones

It' simple to know what time it is in your room right now - just look at the time. Do you know what time it is in another school room all over the world? An option is to use world time zone to calculate how many consecutive hour a place is from you.

24 time belts represent the Meridians of longitudes. In particular, the temperature difference between the different timezones is 15° and each timezone varies by one additional hour between them. In this way, the time in each area is determined by the time of the day at dawn and dusk.

However, the use of time zone can be bewildering for several different purposes. Firstly, some coutries have several different time zone, and these different areas do not always fit together perfect with certain meridian curves. Also keep in mind that with 24 time zone, the time in a different place between 0 and 24 hrs can be different from yours, and it can even be a different date!

If you could somehow use a unified time domain around the world, what would make it simpler to know what time is in another place? This is exactly what Universal Time or "UT" was developed for - to give a unique time taking technique, a unique time domain that everyone would comprehend, and that would prevent the confusing of locale time domains.

The UT is also referred to as Greenwich Mean Time ('GMT'). On what is UT used? The UT is calculated on the basis of Greenwich time. This means that the UT timekeeping is the same as in Greenwich England. As the UT is built on this unique time domain, it is a unified default timing.

So if you use UT to determine a certain time, your own time does not matter anymore. For what is UT used? As the UT is an internationally recognised timekeeping system, it is used in important areas such as formal world affairs, railways, other public transport, defence timekeeping and even science such as satellite, meteorology and space.
