(Continuation from yesterday)

Since ancient times, even in our country, a enormous country budget has been introduced for establishing a calendar, and determining determine the time.

For example, a sundial is convenient to obtain the time easily, with just setting the midline at noon.

However it is useless when cloud, rain day and night.(the moon and stars are used at night)

So, candle(fire clock) and gaze of water tank(hourglass) and watchers were needed in pairs.

And the tell the hour by bell ringing was also needed. Like this, the state has spend much cost to control and manage the time.

Even now, NICT (jurisdiction of the Ministry of Internal Affairs and Communications) sends out standard radio waves used for radio clocks and operation management of NTP servers used on the Internet.

JAXA (Cabinet Office, Ministry of Internal Affairs, Ministry of Education, Culture, Sports, Science and Technology, Ministry of Economy, Trade and Industry jointly jurisdiction) is trying to be able to acquire a phenomenal precision time anywhere in Japan, by sending radio waves from Quasi-Zenith Hygiene (Michibiki) which is a system that supports existing GPS.
