Seoul does not observe daylight saving time, so the clock stays on Korean Standard Time (UTC+9) all year. That makes the gap to places that do switch, like New York or London, change by an hour twice a year.
Good to know
Korea Standard Time is UTC+9, the same as Tokyo. South Korea last used daylight saving time in 1988, around the Seoul Olympics.
