The country will be pushing their clocks back 30 minutes starting Aug. 15

North Korea clocks will be ticking to a whole new time due to a recent government decision.

According to CNN, the country’s state news agency, KCNA, announced all citizens should set their clocks back 30 minutes on Aug. 15, a switch that will set North Korea apart from every other time zone.

The date marks the 70th anniversary of North Korea’s liberation from Japan. By pushing the time 30 minutes back to GMT+08:30, the country is restoring “Pyongyang time,” which was the time zone in North Korea before Japan colonized it.

North Korea already runs on its own calendar, counting from the 1912 birth of their founding leader, Kim Il Sung, making the year Juche 104. Other countries have started remarking on how this new change will affect foreign relations.

“Some difficulties are likely to come in inter-Korean exchanges,” said South Korean Unification Ministry spokesman Jeong Joon-hee.

Jooh-hee said the new time zone is also likely to have negative effects on the integration of the two countries.
