A note on daylight saving
Los Angeles observes daylight saving but Seoul does not, so the gap between them changes by an hour for part of the year. The 16 hours shown here is the current offset; expect it to shift around the daylight-saving changeovers (typically late March and late October in the Northern Hemisphere).
