North Korea is to establish its own time zone to mark its liberation from Japanese colonial rule.
Pyongyang will put its clocks back by 30 minutes on 15 August – the 70th anniversary of Korea’s liberation from Japanese rule at the end of World War II.
North Korea’s office Central News Agency says the establishment of “Pyongyang time” will banish that legacy.
Local time in North and South Korea and Japan is currently the same - nine hours ahead of GMT. It was set during Japan's rule over what was single Korea from 1910 to 1945.
North Korea will establish its new time zone this month
"The wicked Japanese imperialists committed such unpardonable crimes as depriving Korea of even its standard time while mercilessly trampling down its land with 5,000-year-long history and culture and pursuing the unheard-of policy of obliterating the Korean nation," the KCNA dispatch said.
The North's move appears to be aimed at bolstering the leadership of young leader Kim Jong Un with anti-Japan, nationalistic sentiments, said Yang Moo-jin, a professor at the University of North Korean Studies in Seoul. Kim took power upon the death of his dictator father, Kim Jong Il, in late 2011.
Many Koreans, especially the elderly, on both sides of the border still harbor deep resentment against Japan over its colonial occupation.
The Real North Korea
Hundreds of thousands of Koreans were forced to fight as front-line soldiers, work in slave-labor conditions or serve as prostitutes in brothels operated by the Japanese military during the war.
South Korea says it uses the same time zone as Japan because it's more practical and conforms to international practice.
Seoul's Unification Ministry said Friday that the North's action could bring minor disruption at a jointly-run industrial park at the North Korean border city of Kaesong and other inter-Korean affairs.
Spokesman Jeong Joon-Hee said the North's new time zone could also hamper efforts to narrow widening differences between the Koreas.
The two Koreas were divided into the capitalist, U.S.-backed South and the socialist, Soviet-supported North after their 1945 liberation. They remain split along the world's most heavily fortified border since their 1950-1953 Korean War ended with an armistice, not a peace treaty.
Most time zones in the world differ in increments of an hour and only a small number of countries like India, Iran and Myanmar use zones that are offset by a half-hour. Nepal is offset by 45 minutes.
The time zone that North Korea plans to use is what a single Korea adopted in 1908, though the peninsula came under the same Japanese zone in 1912, two years after Tokyo's colonial occupation began. After the liberation, North Korea has maintained the current time zone, while South Korea had briefly used the old zone from 1954 to 1961.
