Nevertheless, the line in Online Spiele Kinder old Englische Spiele Auf Deutsch Umstellen Pc courtyard today differs no more than a few metres from that imaginary line which is now the prime meridian of the world. Wessel, W. Source: Greenwich Mean Time.
It was gradually adopted for other purposes, but a legal case in held " local mean time " to be the official time. For example, our polling booths were opened, say, at 8 13 and closed at 4 13 p.
On 1 January , GMT was superseded as the international civil time standard by Coordinated Universal Time, maintained by an ensemble of atomic clocks around the world.
Universal Time UT , a term introduced in , initially represented mean time at Greenwich determined in the traditional way to accord with the originally defined universal day ; from 1 January as decided by the International Astronomical Union in Dublin in , at the initiative of William Markowitz this "raw" form of UT was re-labelled UT0 and effectively superseded by refined forms UT1 UT0 equalised for the effects of polar wandering  and UT2 UT1 further equalised for annual seasonal variations in Earth rotation rate.
Indeed, even the Greenwich meridian itself is not quite what it used to be—defined by "the centre of the transit instrument at the Observatory at Greenwich".
Although that instrument still survives in working order, it is no longer in use and now the meridian of origin of the world's longitude and time is not strictly defined in material form but from a statistical solution resulting from observations of all time-determination stations which the BIPM takes into account when co-ordinating the world's time signals.
Nevertheless, the line in the old observatory's courtyard today differs no more than a few metres from that imaginary line which is now the prime meridian of the world.
Historically, GMT has been used with two different conventions for numbering hours. The long-standing astronomical convention, dating from the work of Ptolemy , was to refer to noon as zero hours see Julian day.
This contrasted with the civil convention of referring to midnight as zero hours dating from the Roman Empire. The latter convention was adopted on and after 1 January for astronomical purposes, resulting in a discontinuity of 12 hours, or half a day.
The instant that was designated "December Legally, the civil time used in the UK is called "Greenwich mean time" without capitalisation , according to the Interpretation Act , with an exception made for those periods when the Summer Time Act orders an hour's shift for daylight saving.
The Interpretation Act , section 9, provides that whenever an expression of time occurs in an Act, the time referred to shall unless otherwise specifically stated be held to be Greenwich mean time.
Under subsection 23 3 , the same rule applies to deeds and other instruments. Several countries define their local time by reference to Greenwich Mean Time.
Greenwich Mean Time is used as standard time all year round in the following countries and areas:. Since legal, political, social and economic criteria, in addition to physical or geographical criteria, are used in the drawing of time zones, actual time zones do not precisely adhere to meridian lines.
Following is a list of the incongruencies:. From Wikipedia, the free encyclopedia. The prime meridian, determined by the conference, runs through Greenwich, in the UK, giving us Greenwich Mean Time.
Other time zones are counted to the east and west of this line, either plus or minus hours from GMT. Each country sets its own time zone within this framework, so some zones extend beyond the meridian for convenience, while others, like India, take on half hours.
Kiribati even extended its time zone miles east in , to include Caroline Island in the same zone and, as it straddled the Date Line opposite the GMT meridian, the same date as the country's other islands.
The development of the world wide web in the s led to calls for a standardised internet time, as people in cyberspace were no longer bound by geography.
Swatch even invented a concept called beat time that split each day into 1, beats on a decimal system, eradicating time zones entirely.
