South Korea uses Korea Standard Time (KST), IANA identifier Asia/Seoul.
Korea Standard Time covers the whole country and shares its offset with Tokyo.
South Korea does not observe daylight saving time. KST is always UTC +09:00, the same as Japan.
The second panel shows UTC beside the local clock, and the roller lets you check any UTC hour against KST — useful when a call, deadline or flight time is published in UTC.
