However, adding the time zones of 2 uninhabited US territories, Howland Island and Baker Island, brings the total count to 11 time zones. In addition, Alaska, Hawaii, and 5 US dependencies all have their own time zones.
Since Howland Island and Baker Island constitute the world's westernmost landmasses in relation to the International Date Line, making them the last places on Earth where any date exists, they are sometimes assigned a theoretical 12th timezone called Anywhere on Earth (AOE). They will become active again after the next clock change as Daylight Saving Time begins or ends.
Since 1967, the US Department of Transportation (DOT) has been responsible for governing time zones in the country. In addition, the uninhabited atolls of Baker Island (AOE) and Wake Island (WAIT) add to the timezone count, making 11 the total number of time zones in the US.
The world timezone map uses a repeating color scheme to designate the different standard time zones observed in each country. The world timezone map indicates the standard time zones actually observed.
This line runs through the United Kingdom, France, Spain, Algeria, Mali and Ghana in Africa. To see more detail view our larger format world timezone map.
The words “daylight” or “summer” are then usually included in the name, and the local time is usually set forward 1 hour. Theoretically, each 1-hour timezone is 15 degrees wide, indicating a 1-hour difference in mean solar time.
Some geographically large (wide) countries, like India and China, use only 1 timezone, while it would have been natural to expect several, like in the US or Australia. Every place on Earth is measured in terms of its distance east or west of the prime meridian (0° longitude) in Greenwich, London, United Kingdom.
This is also the reference point for Coordinated Universal Time (UTC) with 1 hour per 15 degrees longitude. But several time zones have only 30 and 45 minutes offsets, making the total number worldwide much higher.
The International Date Line is located halfway around the world from the prime meridian (0° longitude) or about 180° east (or west) of Greenwich, London, UK, the reference point of time zones. On timeanddate.com's Timezone Map, the IDL is shown as a black line (see image).
Depending on which timezone the country follows, the time difference on either side of the line is not always 24 hours. Every day between 10:00 and 11:59 UTC, three different dates on the calendar are in use at the same time on Earth.
For example, when the Republic of Kiribati gained independence from being a British colony in 1979 some islands were on one side of the dateline, and the rest were on the other. The 180° meridian was selected as the International Date Line because it mostly runs through the sparsely populated Central Pacific Ocean.
Word forms: plural time zones countable noun timezone is one of the areas into which the world is divided where the time is calculated as being a particular number of hours behind or ahead of GMT. US Webster’s New World College Dictionary, 4th Edition.

Some countries have adopted non-standard time zones, usually 30 minutes offset which have a * designation. While the world is divided into 24 time zones There has to be a place where there is a difference in days There should be a place where the day truly “starts” on the planet. Thus, the 180° line of longitude, exactly one-half way around the planet from Greenwich, England and 0° longitude is approximately where the International Date Line is located.
The International Conference in 1884 deemed that there would be a single Universal Day and that this would begin at mean midnight at Greenwich. Twenty five time zones were established to the east and west of Greenwich with the International Date Line lying along the 180° line of longitude. The line deviates in places to avoid crossing any land.
Along this line the calendar moves into a new day but only in local time, which is measured relative to Greenwich Mean Time. The earliest recommendations issued referring to the date line appear to date from 1899 and 1900 Two adjustments of the date line took place in 1910 near the island chain of Hawaii and between Samoa and the Chatham Islands 11. Philippines 1844 Alaska 18 October 1867 Samoan Islands and Tokelau 4 July 1892 12.
over the years, the position of the International Date Line has changed several times. When the United States bought Alaska in 1867 the line was moved to the west of it.the most recent change in the line was in 1995 when Kiribati moved a large segment of it to the east, so that the entire nation would be on the same side of the International Date Line.
Let's suppose you leave the United States on Tuesday morning. Since you're traveling west the time advances slowly thanks to time zones and the speed at which your airplane flies, but once you cross the International Date Line, its suddenly Wednesday. On the reverse trip home you fly from Japan to the United States.
You leave Japan on Monday morning but as you cross the Pacific Ocean, the day gets later quickly as you cross time zones moving eastward in an replace. However, once you cross the International Date Line, the day changes to Sunday.
The solution is to use the command line program tzutil.exe or PowerShell. Normally, even standard users can change the timezone settings in Windows.
However, in Server 2019, not even administrative privileges are sufficient for this action. If you try to change the timezone in the control panel, the action will fail.
You will receive a notification that you do not have the permissions to perform this task and that you should contact the administrator. As expected, the settings' app is also unable to configure the timezone.
Here, you do not even get an error message; the dialog simply resets itself to the original timezone after exiting. The latest cumulative updates do not eliminate this bug.
Changes to the timezone via the settings app simply remain ineffective But if you still want to use a GUI for this task, you can circumvent the problem by starting the control panel's time date. Cpl applet directly, with administrative rights.
The direct execution of the time date applet with administrative rights fixes the problem If you prefer PowerShell for this task, the Get-TimeZone and Set-TimeZone cadets serve this purpose.
The following command shows all time zones for Australia: This page describes how to check your time and timezone in any Mozilla application.
Note: The web page is in the United States, but you can use it no matter where you are, because UTC is always the same everywhere in the world. To change your time and timezone settings, use your operating system.
On Mac OS X, please go to System Preferences > Date & Time. If you wanted to change the year as well, you could type “date 073123161998.
In the headers at the top of the source, look for the line that begins: Date: When your e-mail program displays the e-mail's date and time, it normally converts them to your timezone.
