(CNN) North Korea is its own world in many ways. Now, it is getting its own time zone to match.

State news agency, KCNA, has announced that North Korea will set its clocks back by 30 minutes to "Pyongyang time" on August 15--the 70th anniversary of liberation from Japan.

That will reset the time to GMT+08:30, as it was before Japanese colonization.
