National Institute of Information and Communications Technology (NICT), an incorporated administrative agency, is in charge of deciding and maintaining Japan Standard Time. The managing system (JavaScript Version) of this page keeps adjusting the WWW server's clock to Japan Standard Time, displaying the adjusted clock time. It is so devised that, when a user's PC accesses this site, it acquires the time information from the WWW server, and its browser side's clock display starts running autonomically.


The current time provided by the WWW server:
Japan Standard Time (JST)
Coordinated Universal Time (UTC)
International Atomic Time (TAI)

Your computer's internal time:
