8+12 hours ahead of GMT, UTC+08:30. In 1912, during the Japanese occupation of Korea, the Governor-General of Korea changed standard time to UTC+09:00 to align with Japan Standard Time. However, in 1954, the South Korean government under President Syngman Rhee reverted the standard time to UTC+08:30. Then in 1961, under the military government of President Park Chung-hee, the standard time was changed back to UTC+09:00 once again. [8]

In order to accommodate American television viewers, South Korea observed daylight saving time (UTC+10:00) when Seoul hosted the 1988 Summer Olympics. The one-hour time change meant that many daytime events could be broadcast live from South Korea when it was prime time on the U.S. east coast. [4]

North Korea also uses Korea Standard Time. From August 2015 to May 2018, North Korea changed its time zone to UTC+08:30, a time zone known as Pyongyang Standard Time, [9] [10] but the change was reverted to promote Korean unity. [11] [12]

Atlantic Time Zone Time zone (UTC−04:00)

The Atlantic Time Zone is a geographical region that keeps standard time—called Atlantic Standard Time (AST)—by subtracting four hours from Coordinated Universal Time (UTC), resulting in UTC−04:00. AST is observed in parts of North America and some Caribbean islands. During part of the year, some portions of the zone observe daylight saving time, referred to as Atlantic Daylight Time (ADT), by moving their clocks forward one hour to result in UTC−03:00. The clock time in this zone is based on the mean solar time of the 60th meridian west of the Greenwich Observatory.
