Fiftieth meet scientists from different countries today and tomorrow in closed session in North West London Academy of Sciences under the auspices of the British "Royal Society", to discuss a new definition of timing, so that the GMT forgotten.
This raises the British press, According to The Sunday Times Britain will lose Greenwich Mean Time, which form "for more than 120 years a symbol of Britain's role in the reign of Queen Victoria as a great power."
The Greenwich Mean Time, which is named after a line length which passes city of Greenwich in London has been adopted global reference in a conference held in Washington in 1884.
Under the new definition of time to give up entirely on the timing, "Solar", which is based on the rotation of the Earth and measured by astronomers for more than 200 years based on the Greenwich line.
Has stopped the world for forty years since the adoption of Greenwich Mean Time, it remains with the Standard Time in Britain, and still is a reference in determining the time.
And adopted an international conference held in 1972, "Coordinated Universal Time," which is calculated for seventy laboratories in the world by 400 hours of "atomic" based on the resonant frequency of the cesium atom to set the time.
The timing is different atomic fractions of a second at the time specified by the earth's rotation, given that more accurate.
Thus, added, "one second" almost every year to maintain the relationship between time and the Earth's rotation. This is the second that scientists propose, delete, and thus totally abandon Greenwich Mean Time.
And this proposal is gaining importance due to the work of communication networks and navigation systems via satellite, such as a GPS U.S. "GPS" and a "GLONASS" and soon two Russian "Galileo" and European "Beidou" Chinese. Some of these devices over the second-in contrast to others, which poses a problem in determining the time.
In January, the proposal will be subject to abandonment of the second additional vote to the International Telecommunication Union in Geneva.
In the case of adoption of this proposal, will be gradually moving away from the atomic time solar time at minutes after a period ranging between 60 and 90 years and the average of one hour after 600 years.
Since this proposal raised objections from several bodies such as China, it was decided to "Royal Society" open the way for future amendments.
And thus may be assigned the task of the conference to think another way to determine the time, as the earth's rotation, ie, add one hour for example, after hundreds of years.
