GMT/UTC -5 hrs - time now
Greenwich Mean Time (GMT/UTC) minus 5 hrs. offsets apply to Eastern Time only, during Daylight Saving Time the offsets are -4. Type your position or any place of your choosing to make further comparison. Following country or region use the -5 offsets in either Daylight Saving Time or Daylight Saving Time as specified.
Greenwich Mean Time (GMT) - GMT
There are only a few sites currently on GMT, as most sites in this time area are currently set to DST and IST or BST time. To find the right time for your area, please use the box on the right. The Greenwich Mean Time (GMT) has no offsets to the Coordinated Universal Time (UTC).
It is used during the default time in : Greenwich Mean Time is often referred to as this time area. However, some places monitor DST and DST in DST and therefore use IST (Irish Standards Time) or BST (British Summers Time) in DST. A message sent by someone in the Greenwich Mean Time (GMT) time region has the time region "+000000" in the message header.
However, "+000000" does not have to be in Greenwich Mean Time as other time zone may have the same setpoint. Continents/areas using GMT in winters and IST or FST in summers: Antarctic sites with GMT in sommer and CEST in winter: There are some time zone that have the same offsets as GMT, but can be found under a different name: Did you mean IS or SST?

It is the area indicated at the centre of the card by the inscription "0", colored green: bright colors indicate where normal time is maintained throughout the year, bright colors indicate where DST is monitored. Bright colors indicate where default time is maintained throughout the year; deep colors indicate where default time is maintained.
GMT is the mean time of the sun at the Royal Observatory in Greenwich, London, starting at noon. It has been computed in different ways at different periods in the past, inclusive of noon; therefore, it cannot be used to give an exact time unless a specific time is given.
Due to the Earth's irregular velocity in its elliptic trajectory and inclination, midday (12:00:00:00) GMT is seldom the precise time when the Earth passes the Greenwich meridian and attains its highest point in the heavens. You can have this incident up to 16 min before or after midday GMT, a deviation computed by the Equation of Time.
Lunch GMT is the mean instant of this occurrence that makes up the phrase "mean" in Greenwich Mean Time. Greenwich Mean Time is the statutory time in some jurisdictions (e.g. the UK) in winters and the public uses the name. When the United Kingdom became an Advanced Seafaring Nations, seafarers held at least one GMT data logger to determine their latitude from the Greenwich Meridian, which was usually regarded as the zero degree of latitude and adopted by the 1884 International Conference of Meridians.
The synchronization of the data logger to GMT had no influence on the ship time, which was still sun time. However, this practise, in combination with seafarers from other countries who drew from Nevil Maskelynes' Moon Distance methodology on the basis of Greenwich observation, resulted in GMT being used throughout the world as the default time regardless of place.
The majority of time zone were GMT time, off-set by a number of hour (and possibly half or quarters of an hour) "before GMT" or "after GMT". In 1847 Greenwich Mean Time was taken over by the Clearing House on the whole of Great Britain and in the following year by almost all railways, from which the concept "Railway Time" is deduced.
Slowly it was adopted for other uses, but in a 1858 case the "local interim" was considered the state time. On 14 May 1880, a note was published in The Times, signing Clerk to Justices, saying that "Greenwich Day is now respected almost everywhere in England, but it seems that Greenwich Day is not a time for law.
Our voting cubicles, for example, were opened at 8.13 a.m. and shut at 4.13 p.m. " This was altered later in 1880 when Greenwich Mean Time was introduced lawfully throughout the UK. In 1916 Ireland introduced the GMT, thus replacing the Dublin interim period. 9 ] The Greenwich Observatory's one-hour time signal was first transmitted on February 5, 1924, making the time bounce at the station superfluous.
GMT was replaced on 1 January 1972 as the civilian global time code by Coordinated Global Time, which is operated by an array of nuclear clocks around the United States. UT (Universal Time), a concept invented in 1928, first depicted the mean time in Greenwich traditionally established to correspond to the original definition of UT; from 1 January 1956 (as adopted by the IAU in Dublin in 1955 at the instigation of William Markowitz), this "raw" version of UT was re-marked as PT0 and effective through sophisticated UT1 (UT0 compensated for the impact of Arctic wandering) and UT2 (UT1 compensated for the impact of Arctic wandering) and UT2 (UT1 compensated for annually seasonal), respectively, from 1 January 1956 onwards (as adopted by the IAU in Dublin in 1955 at the instigation of William Markowitz).
In fact, even the Greenwich meridian itself is not quite what it used to be - delineated by "the center of the transiting tool at the Greenwich Observatory". Though still functional, this tool is no longer in use, and now the original longitude and time of the world is no longer rigorously materially delineated as a source of meridians, but rather as a result of a statistic approach derived from observation of all the time determining sites which the BIPM considers in coordinating the time signal of the globe.
It'?s got the Greenwich time and latitude. GMAT (Greenwich Mean astronomical time) was created to clearly reference the prior noon-based GMT conventions. In the 1968-1971 experiments, when the UK did not return to Mean Time in winters, the year-round BST was referred to as BST (British Standard Time).
The BBC radios transmit the "six dots" of the Greenwich time signal. Known after its initial creation at the Royal Greenwich Observatory, it is geared to coordinated world time and is either Greenwich Mean Time or British Summer Time, depending on the season. A number of different nations use Greenwich Mean Time to determine their time.
Standards Time (Amendment) Act, 1971, Section 1, and Interpretation Act 2005, Part 4, Section 18(i). Note that this relates to the "standard time" for the different counties defined in terms of "Greenwich Mean Time", but does not use the term "Greenwich Mean Time". A number of jurisdictions, such as Nova Scotia (Time Definition Act. R.S., c. 469, s. 1), have their own laws which explicitly mention either "Greenwich Mean Time" or "Greenwich Mean Solars Time".
The Greenwich Mean Time is used as the default time in the following nations, which also drive their watches by one additional hour GMT+1 in daylight savings. The Republic of Ireland, where it is referred to as Ireland Standards Time (IST) - official conversion to GMT in late May. The Greenwich Mean Time is used as the default time throughout the year in the following nations and territories:
Given that the subscription of time zoning uses juridical, policy, social as well as economical as well as geographic factors, the real time zoning does not correspond exactly to the median line. If the time region "GMT" were geographically mapped, it would be the area between the 7°30'W and 7°30'E channels.
Consequently, there are places in Europe that use a different time zones despite their location in an area with a "physical" time ( "UTC") (especially UTC+1); vice versa, there are places in Europe that use a different time zones ("UTC") although their "physical" time zones are UTC-1 (e.g. most Portuguese) or UTC-2 (most western part of Iceland).
Lowestoft in the United Kingdom is the most eastern European colony where ATC is used, with only 1°45'E, because the European timezone is "shifted" to the western part of Europe. More likely, in the mid-1970s, when Portugal was in Central European Time all year round, it was only at 08:30 a.m. in Lisbon that it received lights in winters.
Spain's time is the immediate outcome of Franco's order to the president (published in Boletín Oficial del Estado of 8 March 1940), which abandoned Greenwich Mean Time and brought forward the watches by one extra hour with effect from 23:00 on 16 March 1940. It is an outstanding example of policy criterion used when subscribing to time zones: the time shift was adopted "taking into account the ease of the time march at home in the country after other EU countries".
As a result of this policy choice, Spain is two hrs ahead of its average time in the summers and one hrs ahead of its average time in the winters, which may explain the infamous lateness for which the nation is known.
