Time zone world map4/10/2024 ![]() ![]() Astronauts aboard the ISS log events against GMT/UTC just to simply procedures. It is therefore passing through multiple time zones a day. The International Space Station is travelling at 17,500 mph (28,000 km/h) and can do 16 revolutions of the earth in a day. ![]() So instead of being +9 UTC, for all intense and purposes Adelaide is +9.5 UTC. There are places around the world like Adelaide in Australia that should technically be 1 hour behind the large and influential cities of Sydney and Melbourne but have agreed to adjust the time zone purely for commercial reasons. Realistically this would actually just make things more difficult for individuals even if business would probably applaud the innovation. Pundits feel this would simplify things as it would reduce the number of time zones and countries like the USA would only have 1 time zone and just use daylight saving to adjust for daylight hours. ![]() There have been arguments to increase the length of each time zone to 2 or 3 hours. Finally we have Russia, Belarus and Turkey grouped together in +3 UTC, although it is still debatable if Turkey is considered part of Europe. Finland, Estonia, Latvia, Lithuania, Ukraine, Moldova, Roumania, Bulgaria and Greece are grouped together in +2 UTC. Norway, Sweden, Denmark, The Netherlands, Belgium, Spain, Italy Germany, Luxembourg, Czech Republic, Slovakia, Austria, Switzerland Poland, Hungary, Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Kosovo, Albania and Macedonia are all grouped together in +1 UTC. The UK, Portugal, Ireland and Iceland are grouped together in the 0 UTC. Islands are generally included with the large landmasses that are nearby although in cases like Indonesia that is one big archipelago there are multiple time zones spread across the country. This is because time zones only apply to landmasses above the oceans and will generally try to take sovereign territories into account. You can see that the each timezone on the world map above is not straight. Interestingly it is these tiny little countries that are the first to celebrate new years every year.Įach timezone is one hour in length so there are 24 separate time zones as there are twenty four hours in a day. The countries in this furthest timezone are territories like American Samoa and the Jarvis Islands. The World Map we have above is centred in Greenwich and to the left and right are the farthest points away from this line and are -11 hours away from Coordinated Universal Time. The map is based around what was formerly known as Greenwich mean time but is now known as Coordinated Universal Time. The world timezone map begins and ends at Greenwich a suburb of London in the UK. In this era of transcontinental corporations and business enterprises, time zones are more important than ever. Humans need to sleep and we generally do this activity at night time. They basically follow the cycle of the sun as the earth spins and different parts of the world face the sun. Because some countries, islands and states do not want to be divided into several zones, the zones' boundaries tend to wander considerably from straight north-south lines.The planet earth is broken up into regions we call time zones. The international dateline was drawn to generally follow the 180 meridian in the Pacific Ocean. The 24 standard meridians, every 15 east and west of 0 at Greenwich, England, were designated the centers of the zones. C., applied the same procedure to zones all around the world. On November 1, 1884, the International Meridian Conference in Washington, D. At noon, on November 18, 1883, telegraph lines transmitted GMT time to major cities where authorities adjusted their clocks to their zone's proper time. That year, the United States was divided into four time zones roughly centered on the 75th, 90th, 105th, and 120th meridians. The time convention begins with Universal Coordinated Time (UTC) which is also commonly referred to as Greenwich Mean Time (GMT) being located at the. In theory time zones are based on the division of the world into twenty four time zones of 15 degrees longitude each. Until 1883 most railway companies relied on some 100 different, but consistent, time zones. The world time zone map indicates the standard time zones actually observed. The problem of keeping track of over 300 local times was overcome by establishing railroad time zones. Until the 1860s most cities relied upon their own local “sun” time, but this time changed by approximately one minute for every 12 miles traveled east or west. Time zones did not become necessary in the United States until trains made it possible to travel hundreds of miles in a day.
