Clock time and solar time in South Korea
A country's clocks are a political choice, not an astronomical one, so they rarely line up with its own sun. Measured against local solar time, the clock in Seoul runs 32 minutes ahead of the sun.
Solar noon there falls 32 minutes after 12:00 on the clock.
How much daylight changes through the year
Daylight is governed by latitude, not by the clock. Seoul, at 37.6° north, gets 14 hours 46 minutes of daylight on the longest day of the year and 9 hours 34 minutes on the shortest.
That swing is the same whatever the clock says, which is why daylight saving moves working hours around inside the day without creating a single extra minute of light.
