International Conference Held at Washington - Fixing a Prime Meridian and a Universal Day
In 'International Conference Held at Washington - Fixing a Prime Meridian and a Universal Day' by the International Meridian Conference (1884: Washington, D.C.), the reader is introduced to a comprehensive documentation of the discussions and decisions made at the conference that established the Greenwich Meridian as the Prime Meridian of the world. This book delves into the technical aspects of determining longitude, the history of meridian systems, and the implications of having a universal standard for timekeeping. Written in a highly formal and factual style, this text serves as a pivotal piece of historical documentation in the field of international cooperation and standardization. The...
Zero Degrees
Space and time on earth are regulated by the prime meridian, 0°, which is, by convention, based at the Royal Observatory, Greenwich. But the meridian’s location in southeast London is not a simple legacy of Britain’s imperial past. Before the nineteenth century, more than twenty-five different prime meridians were in use around the world, including Paris, Beijing, Greenwich, Washington, and the location traditional in Europe since Ptolemy, the Canary Islands. Charles Withers explains how the choice of Greenwich to mark 0° longitude solved complex problems of global measurement that had engaged geographers, astronomers, and mariners since ancient times. Withers guides readers through th...
One Time Fits All
One Time Fits All tells the story of the development, integration, and obstacles overcome in setting an the International Date Line, establishing the worldwide system of Standard Time zones, and adopting Daylight Saving Time—including their global impacts on how the general public keeps time today.

Greenwich Time and the Longitude: Official Millennium Edition
The history of the Royal Observatory, Greenwich has been revised to coincide with the Millenium. Color illustrations and updated text tell the story of Greenwich from its foundations in 1676 to its present status as Longitude 0°, the world's Prime Meridian for measuring longitude and time. The book covers the importance of longitude for navigation and traces the history of Greenwich Time, the basis of universal time-keeping. The book is co-published with the National Maritime Museum, where Derek Howse was the former Head of Navigation and Astronomy.
The Clocks Are Telling Lies
Until the nineteenth century all time was local time. On foot or on horseback, it was impossible to travel fast enough to care that noon was a few minutes earlier or later from one town to the next. The invention of railways and telegraphs, however, created a newly interconnected world where suddenly the time differences between cities mattered. The Clocks Are Telling Lies is an exploration of why we tell time the way we do, demonstrating that organizing a new global time system was no simple task. Standard time, envisioned by railway engineers such as Sandford Fleming, clashed with universal time, promoted by astronomers. When both sides met in 1884 at the International Meridian Conference ...
Sky and Ocean Joined
As one of the oldest scientific institutions in the United States, the US Naval Observatory has a rich and colourful history. This volume is, first and foremost, a story of the relations between space, time and navigation, from the rise of the chronometer in the United States to the Global Positioning System of satellites, for which the Naval Observatory provides the time to a billionth of a second per day. It is a story of the history of technology, in the form of telescopes, lenses, detectors, calculators, clocks and computers over 170 years. It describes how one scientific institution under government and military patronage has contributed, through all the vagaries of history, to almost two centuries of unparalleled progress in astronomy. Sky and Ocean Joined will appeal to historians of science, technology, scientific institutions and American science, as well as astronomers, meteorologists and physicists.
