For over 150 years the United States Nautical Almanac Office has published The Nautical Almanac, first as part of the American Ephemeris and Nautical Almanac, and then on its own, to provide the US Navy with a convenient form of the astronomical data used for celestial navigation. This book is still the standard resource for marine celestial navigation for the U.S. Navy. The book is produced in collaboration with Her Majesty's Nautical Almanac Office, part of the U.K. Hydrographic Office. That Office maintains the copyright on the material it produces. The Nautical Almanac contains the following data tabulated at hourly intervals to a precision of 0.1 arcminute: the Greenwich hour angle and declination of the Sun, Moon, and navigational planets; the Greenwich hour angle of Aries; positions of the navigational stars; rise and set times of the Sun and Moon for a range of latitudes; and other data. Each edition also contains a sight reduction table; sight reduction formulas; and various correction tables for sight reduction. There is a useful concise sight reduction form at the back of the book. The Nautical Almanac is available several months in advance of its edition date.

The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.
