Japan standard time
Before the Meiji era —each local region had its own time zone in which noon was when the sun was exactly at its culmination. As modern transportation methods, such as trains, were adopted, japan standard time, this practice became a source of confusion. For example, there is a difference of about 5 degrees longitude between Tokyo and Osaka and because of this, a train that japan standard time from Tokyo would arrive at Osaka 20 minutes behind the time in Tokyo. InOrdinance 51 was issued in response to this problem, which stated:.
Standard Time in Japan is legally defined to represent the local time at the th eastern meridian, an arrangement that originated in the Meiji era and dates back as far as [1]. Considering that Earth rotates degrees in 24 hours, this means that time in Japan is exactly 9 hours ahead of the time in Greenwich, which used to provide the standard known as Greenwich Mean Time GMT , based on exact astronomical measurements. Today, the international time scale of Coordinated Universal Time UTC is based on precise atomic clocks, but the 9-hour time difference of Japan Standard Time has been maintained. The Japanese Ministry of Internal Affairs and Communications MIC is responsible for providing standard frequencies, transmitting standard radio waves, and reporting standard time [2]. These tasks have been assigned to us at the National Institute of Information and Communications Technology NICT , where we create, distribute and compare Japan Standard Time signals, both nationally and internationally. Since we interact with time most directly through the change of day and night or the change of seasons, the original units of time were linked to the rotation of the Earth and its motion around the sun. However, the measurements required to achieve greater accuracy became more and more complex, and it was soon found that the rotation of the Earth itself constantly changes due to the effects of tidal friction and the motion of the mantle and atmosphere.
