QUESTION = What exactly is time?

GENERATION = Time is the fourth dimension. It is the dimension we perceive as being different from the three spatial dimensions we perceive. It is the fourth dimension we can move through, time, and also the fourth dimension we can move through, space. It is the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through, and also the fourth dimension we can move through.

RETRIEVAL #5 = Time in physics---parameter. The modern conception of time is based on Einstein's theory of relativity, in which rates of time run differently depending on relative motion, and space and time are merged into spacetime, where we live on a world line rather than a timeline. In this view time is a coordinate. According to the prevailing cosmological model of the Big Bang theory time itself began as part of the entire Universe about 13.8 billion years ago. Section::::Conceptions of time.:Regularities in nature. In order to measure time, one can record the number of occurrences (events) of some periodic phenomenon. The regular recurrences of the seasons, the motions of the sun, moon and stars were noted and tabulated for millennia, before the laws of physics were formulated. The sun was the arbiter of the flow of time, but time was known only to the hour for millennia, hence, the use of the gnomon was known across most of the world, especially Eurasia, and at least as far southward as the jungles of Southeast Asia. In particular, the astronomical observatories maintained for religious purposes became accurate enough to ascertain the regular motions of the stars, and even some of the planets. At first, timekeeping was done by hand by priests, and then for commerce, with watchmen to note time as part of their duties. The tabulation of the 

RETRIEVAL #6 = Time in physics---Time in physics Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. "" is a complex of technological and scientific issues, and part of the foundation of "recordkeeping". Section::::Markers of time. Before there were clocks, time was measured by those physical processes which were understandable to each epoch of civilization: BULLET::::- the first appearance (see: heliacal rising) of Sirius to mark the flooding of the Nile each year BULLET::::- the periodic succession of night and day, seemingly eternally BULLET::::- the position on the horizon of the first appearance of the sun at dawn BULLET::::- the position of the sun in the sky BULLET::::- the marking of the moment of noontime during the day BULLET::::- the length of the shadow cast by a gnomon Eventually, it became possible to characterize the passage of time with instrumentation, using operational definitions. Simultaneously, our conception of time has evolved, as shown below. Section:::
