The Time Now is a reliable tool when traveling, calling or researching. The Time Now provides accurate US network of cesium clocks synchronized time and accurate time services around the world. The universe we inhabit is filled with cycles. Night becomes day, planets rotate around the Sun, seasons change, and so much more. We use these cycles to measure the passage of time, but like the universe's cycles, that was only the beginning. We've also created time zones, calculations down to the millisecond, and various ways to measure them all. Our lives revolve around time which is why we've created a rich and varied database of tools and information that we like to call The Time Now. The Time Now is an accurate tool providing multiple time-related services, various in-depth articles, and more. This database is updated with each new decision of governments or astronomical institutions. The Time Now is currently available in 29 languages. It is used by millions of people worldwide each month as a valuable resource for information, knowledge, and a means of planning and understanding time around the world. Before one can understand time zones, daylight savings, and other methods of measuring time, it would be best to have a grasp of how science defines this concept. Beyond science, this concept is also highly researched and discussed in the realms of religion and philosophy. We cannot reach out and grasp it, nor can we watch it pass, and yet time exists anyway.

At different times in the past, it has been calculated in different ways, including being calculated from noon ; [1] as a consequence, it cannot be used to specify a particular time unless a context is given. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt , noon GMT is rarely the exact moment the Sun crosses the Greenwich Meridian [b] and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time.

Our tools are always up-to-date and our database of information is constantly expanding and growing. C that the Roman Empire would use a solar calendar and it became known as the Julian calendar. The first was that the USA had already chosen Greenwich as the basis for its own national time zone system. The Time Now is an accurate tool providing multiple time-related services, various in-depth articles, and more. Horology is the study of devices used to measure time. Weather observations around the world including surface, radar, and other observations are always taken with respect to a standard time. This meant there was no standard timings for when the day would begin and end, or what length an hour might be. From that time until , the Shepherd master clock was the heart of Britain's time system.

Night becomes day, planets rotate around the Sun, seasons change, and so much more. The concept of these time zones was first suggested in a book written by Quirico Filopanti called Miranda! The actual origin of these devices is not known, but along with sundials these were the first tools used to measure time. For example, China and India both utilize a single time zone despite the fact that their countries are wider than the fifteen degrees of longitude that usually dictates a time zone.
