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. Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time". Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight.

Until the advent of the railways, the United Kingdom used local mean time. Greenwich Mean Time was adopted first by the Great Western Railway in and a few others followed suit in the following years. In it was adopted by the Railway Clearing House , and by almost all railway companies by the following year. It was from this initiative that the term " railway time " was derived. It was gradually adopted for other purposes, but the legal case of Curtis v March in held " local mean time " to be the official time.

But what is GMT and why is it so important? Solar time varies throughout the year, as the time interval between the Sun crossing a set meridian line changes. But each day measured by a clock has the same length, equal to the average mean length of a solar day. Find out about the Prime Meridian. From until , GMT was the international standard of civil time. Greenwich Mean Time is also the name of the time zone used by some countries in Africa and Western Europe, including in Iceland all year round. John Flamsteed came up with the formula for converting solar time to mean time, and published a set of conversion tables in the early s. Soon after, he was appointed as the first Astronomer Royal and moved into the new Royal Observatory in Greenwich. Here he had the best pendulum clocks installed and set them to the local time. At first though, Greenwich time was only really important to astronomers.
