In Norway the standard time is the Central European Time (CET). Norway observes Summer Time (sommertid, daylight saving time). The transition dates are the same as for other European countries.
Svalbard and Jan Mayen observe the same time as the mainland.
Norway stretches more to the west and east than it might look like on a common Mercator projection map. The westernmost point in Norway proper is on 4°30′E longitude, meaning 42 minutes difference between mean solar time and official time, while the easternmost point in Norway proper is on 31°10′E longitude, meaning 64 minutes difference between mean solar time and official time. The difference between those points is 26°41′ or 1 hour 46 minutes. The 15° E meridian passes Norway in the northern part of the country, from north over Vesterålen and Lofoten islands, then Vestfjorden and finally Salten and Saltfjellet, a total distance of about 320 km. The vast majority of the population in Norway lives to the west of the 15°E longitude.
The IANA time zone database contains one zone for the area with ISO 3166-1 alpha-2 code NO (Norway) in the file zone.tab, where it is named "Europe/Oslo". Svalbard is covered by the zone Arctic/Longyearbyen, while Jan Mayen is covered by Atlantic/Jan Mayen. Both are links to Europe/Oslo.

Norway follows the European Union in this matter.
Norway was comparably late to introduce an official standard time, mainly due to the lack of a railway network connecting the country in an east–west direction. Throughout Norway, the main means of transport were by cart onshore and ship at sea, both too slow and unpredictable to have an issue with the local time. With the introduction of the electrical telegraph in 1855 between Kristiania (Oslo) and Drammen, the local time of Copenhagen, Denmark was used for this purpose, until 1866 when it was replaced by Oslo local time. The railways from the Eastern terminus (Østbanen) in Oslo used Oslo local time, while the railways from the Western terminus (Vestbanen) used Drammen local time, a difference of 4 minutes. The unconnected (during 19th century with large gaps to the Oslo network) railways from Bergen and Stavanger used these cities local time, both 22 minutes after Oslo time.
It was not until 1885 the first suggestions came to introduce standard time in Norway, but this met great opposition by influencing groups and locally in the districts of Norway. The most complicated of four propositions was to divide Norway into 5 time zones 15 minutes apart. But none of them was accepted. In 1893 the time issue emerged again, and since the last time, the neighbouring countries Sweden and Denmark had adopted standard time, so also Germany (Central European time). In Norway, the railways in western and eastern Norway were planned to be connected in a few years (happened 1909), and now the proposition to adapt to Central European was widely accepted. Hence, one standard time was introduced January 1., 1895 and has since then remained Greenwich + 1 (Central European time). On this date church clocks was either moved backward (east of 15°E), or forward (west of 15°E), except for Hadsel and Steigen parishes that continued with their local time as their churches lie almost on the 15°E meridian. The local time continued to live on for quite some time, especially in rural communities, where both the local and standard time were in use (the latter being referred to as railway time).
In Norway, summer time was observed in 1916, 1943–45, and 1959–65. The arrangement 1959-65 was controversial, and was discontinued 1965. Their neighbour, Sweden, did not use it during this period. However, in 1980 summer time was reintroduced (together with Sweden and Denmark), and since 1996 Norway has followed the European Union regarding transition dates.
A time zone is an area that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
Norway is a country located in Northern Europe in the northern and western parts of the Scandinavian Peninsula. The majority of the country borders water, including the Skagerrak inlet to the south, the North Sea to the southwest, the North Atlantic Ocean to the west, and the Barents Sea to the north. It has a land border with Sweden to the east and a shorter border with Finland and an even shorter border with Russia to the northeast.
The International Meridian Conference was a conference held in October 1884 in Washington, D.C., in the United States, to determine a prime meridian for international use. The conference was held at the request of U.S. President Chester A. Arthur. The subject to discuss was the choice of "a meridian to be employed as a common zero of longitude and standard of time reckoning throughout the world". It resulted in the recommendation of the Greenwich Meridian as the international standard for zero degrees longitude.
Japan Standard Time, or Japan Central Standard Time, is the standard time zone in Japan, 9 hours ahead of UTC. Japan does not observe daylight saving time, though its introduction has been debated on several occasions. During World War II, the time zone was often referred to as Tokyo Standard Time.
Svalbard and Jan Mayen is a statistical designation defined by ISO 3166-1 for a collective grouping of two remote jurisdictions of Norway: Svalbard and Jan Mayen. While the two are combined for the purposes of the International Organization for Standardization (ISO) category, they are not administratively related. This has further resulted in the country code top-level domain .sj being issued for Svalbard and Jan Mayen, and ISO 3166-2:SJ. The United Nations Statistics Division also uses this code, but has named it the Svalbard and Jan Mayen Islands.
The historic prime meridian or Greenwich meridian is a geographical reference line that passes through the Royal Observatory, Greenwich, in London, England. The modern IERS Reference Meridian widely used today is based on the Greenwich meridian, but differs slightly from it. The prime meridian was first established by Sir George Airy in 1851, and by 1884, over two-thirds of all ships and tonnage used it as the reference meridian on their charts and maps. In October of that year, at the behest of US President Chester A. Arthur, 41 delegates from 25 nations met in Washington, D.C., United States, for the International Meridian Conference. This conference selected the meridian passing through Greenwich as the official prime meridian due to its popularity. However, France abstained from the vote, and French maps continued to use the Paris meridian for several decades. In the 18th century, London lexicographer Malachy Postlethwayt published his African maps showing the "Meridian of London" intersecting the Equator a few degrees west of the later meridian and Accra, Ghana.
Indian Standard Time (IST), sometimes also called India Standard Time, is the time zone observed throughout India, with a time offset of UTC+05:30. India does not observe daylight saving time or other seasonal adjustments. In military and aviation time IST is designated E* ("Echo-Star"). It is indicated as Asia/Kolkata in the IANA time zone database.
Central European Time (CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Madrid Time, Paris Time, Rome Time, Warsaw Time or even Romance Standard Time (RST).
The extreme points of Norway include the coordinates that are farther north, south, east or west than any other location in Norway; and the highest and the lowest altitudes in the country. The northernmost point is Rossøya on Svalbard, the southernmost is Pysen in Mandal, the easternmost is Kræmerpynten on Svalbard, and the westernmost is Hoybergodden on Jan Mayen. The highest peak is Galdhøpiggen, standing at 2,469 m (8,100 ft) above mean sea level, while the lowest elevation is sea level at the coast.
.sj is the Internet country code top-level domain (ccTLD) reserved for the designation Svalbard and Jan Mayen. The domain name registry is Norid, but .sj is not open for registration. The issuing of the domain was based on the ISO 3166 designation of Svalbard and Jan Mayen, which consists of two separately administrated integrated territories of Norway: the Arctic archipelago Svalbard and the nearly uninhabited volcanic island Jan Mayen. .sj was designated on 21 August 1997, at the same time as Bouvet Island was allocated .bv. Both were placed under the .no registry Norid, which is also the sponsor. Norwegian policy states that .no is sufficient for those institutions connected to both Svalbard and Jan Mayen, and therefore the domain is not open to registration. It is Norwegian policy not to commercialize domain resources, so there are no plans to sell .sj. Should the domain later come into use, it will be under regulation of the Norwegian Post and Telecommunications Authority and follow the same policy as .no. There are two second-level domains reserved for the two areas: svalbard.no and jan-mayen.no, but other web addresses are also used.
UTC+01:00 is an identifier for a time offset from UTC of +01:00. In ISO 8601, the associated time would be written as 2019-02-07T23:28:34+01:00. This time is used in:
Malaysian Standard Time or Malaysian Time (MYT) is the standard time used in Malaysia. It is 8 hours ahead of Coordinated Universal Time (UTC). The local mean time in Kuala Lumpur was originally GMT+06:46:46. Peninsular Malaysia used this local mean time until 1 January 1901, when they changed to Singapore mean time GMT+06:55:25. Between the end of the Second World War and the formation of Malaysia on 16 September 1963, it was known as British Malayan Standard Time, which was GMT+07:30. At 2330 hrs local time of 31 December 1981, people in Peninsular Malaysia adjusted their clocks and watches ahead by 30 minutes to become 00:00 hours local time of 1 January 1982, to match the time in use in East Malaysia, which is UTC+08:00. SGT (Singapore) followed on and uses the same until now.
Philippine Standard Time, also known as Philippine Time (PHT), is the official name for the time zone used in the Philippines. The country only uses one time zone, at an offset of UTC+08:00, but has used daylight saving time for brief periods in the 20th century.
The Republic of India uses only one time zone across the whole nation and all its territories, called Indian Standard Time (IST), which equates to UTC+05:30, i.e. five and a half hours ahead of Coordinated Universal Time (UTC). India does not currently observe daylight saving time.
Switzerland uses Central European Time (CET) during the winter as standard time, which is one hour ahead of Coordinated Universal Time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of Coordinated Universal Time (UTC+02:00).
Denmark, including the dependencies Faroe Islands and Greenland, uses six time zones.
Time in the Kingdom of the Netherlands is denoted by Central European Time (CET) during the winter as standard time in the Netherlands, which is one hour ahead of coordinated universal time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of coordinated universal time (UTC+02:00). The Caribbean Netherlands – which consist of the islands of Bonaire, Sint Eustatius and Saba – all observe Atlantic Standard Time (AST) year-round, which is four hours behind coordinated universal time (UTC−04:00).
Finland uses Eastern European Time (EET) during the winter as standard time and Eastern European Summer Time (EEST) during the summer as daylight saving time. EET is two hours ahead of coordinated universal time (UTC+02:00) and EEST is three hours ahead of coordinated universal time (UTC+03:00). Finland adopted EET on 30 April 1921, and has observed daylight saving time in its current alignment since 1981 by advancing the clock forward one hour at 03:00 EET on the last Sunday in March and back at 04:00 EET on the last Sunday in October, doing so an hour earlier for the first two years.
Svalbard, an archipelago in the Arctic Ocean belonging to the Kingdom of Norway, uses Central European Time (CET) during the winter as standard time, which is one hour ahead of Coordinated Universal Time (UTC+01:00), and Central European Summer Time (CEST) during the summer as daylight saving time, which is two hours ahead of Coordinated Universal Time (UTC+02:00). This is shared with the rest of Norway, as is Svalbard's use of daylight saving time, which the territory observes annually by advancing the clock forward on the last Sunday in March and back again on the last Sunday in October. However, as Svalbard experiences midnight sun during the summer due to being located north of the Arctic Circle, it gives daylight saving time no utility, and is only observed in order to make communicating with Norway Proper more convenient. At the 74th parallel north, the midnight sun lasts 99 days and polar night 84 days, while the respective figures at the 81st parallel north are 141 and 128 days.
Time in Liberia is given by a single time zone, denoted as Greenwich Mean Time. Liberia shares this time zone with several other countries, including fourteen in western Africa where it was formerly known as Western Sahara Standard Time (WSST). Liberia has never observed daylight saving time (DST).
