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.
