    Japan Standard Time

    The Japan Standard Time (JST; Japanese 日本 標準 時 , Nihon hyōjunji ; English Japan Standard Time ) was introduced in Japan by decree 51 of July 12, 1886 with effect from January 1, 1888 as standard time ( 標準 時 , Hyōjunji ). Before that, each region had its own regional time.

    After Taiwan came under Japanese rule , the "Standard Time " was renamed "Central Standard Time " ( 中央 標準 時 , Chūō hyōjunji ) and for the Japanese Miyako and Yaeyama Islands by decree 167 of September 24, 1895 with effect from January 1, 1896 , as well as Taiwan and its Penghu Islands , d. H. all areas east of the 125th degree of longitude, a "Western Standard Time " ( 西部 時 時 , Seibu hyōjunji ) with a reference meridian of 120 ° East, d. H. GMT + 8 . By decree 529 of September 24, 1937, the latter decree was repealed with effect from October 1, 1937, i.e. H. returned to a common time zone.

    During the Second World War , the Japanese period also spread to the occupied territories such as B. Singapore introduced; after the withdrawal, the previously valid zone times were reintroduced.

    Summertime

    The US Occupation Authority ( GHQ / SCAP ) introduced a daylight saving time regulation on May 1, 1948 to counter energy bottlenecks. However, since this was implemented with just three days' notice and without prior discussion, it developed into a symbol of the humiliation by the war winners, so that when Japan regained sovereignty in 1952 it was immediately abolished. As a professional group, the farmers were also considered to be the strongest opponents of summer time, since they traditionally worked until dusk and feared that longer hours of sunshine would lead to longer working hours.

    In northern Hokkaidō , which has particularly long hours of sunshine in summer due to its location, the Sapporo Chamber of Commerce, in cooperation with the prefectural government, organized the "Hokkaidō Summer Time Experiment" in 2004 , in which civil servants and employees could move their working hours to one hour earlier on a voluntary basis what would correspond to a working time in summer time. The experiment was repeated in 2005 and the following years, but with less participation. The Ōshū community in Iwate Prefecture put its clocks one hour ahead on June 21, 2006.

    The energy bottlenecks in connection with the shutdown of the Japanese nuclear reactors in response to the Fukushima nuclear disaster in 2011 brought the issue of summer time back into the political focus.

    Korea Standard Time

    The Korea Standard Time (KST; kor. 한국 표준시 , 韓國 標準 時 , Hanguk Pyojunsi ; English Korea Standard Time ) applies in South Korea and North Korea . In South Korea there was a daylight saving time regulation in 1987 and 1988 , since then UTC + 9 has been in effect all year round. The government of North Korea introduced the UTC + 8: 30 time zone on August 15, 2015 , which had already been used from 1908 to 1912, but switched back to UTC + 9 on May 5, 2018.
