Should South Korea swap time zones to Pyongyang Time?

North Korea is to switch to a new time zone to mark its liberation from the Japanese at the end of World War Two, says state media.

North and South Korea are currently in the same time zone as Japan, which is nine hours ahead of GMT.

But Pyongyang Time will see the clocks put back by 30 minutes on 15 August.

Steve Evans reports on whether there is appetite in South Korea to also switch time zones.
