South Korea has one time zone, Korea Standard Time (UTC+9), which is abbreviated KST. South Korea currently does not observe daylight saving time.
From May 8 to October 9 in 1988, daylight saving time was tested to better accommodate the calendar of competitions held during the 1988 Summer Olympics in Seoul.
The opening ceremony of the 1988 Summer Olympics took place at Seoul Olympic Stadium in Seoul, South Korea, on 17 September 1988 at 10:30 KDT (UTC+10). The official song of this game was "Hand in Hand", which was performed by Koreana. The Games were officially opened by President of the Republic of Korea Roh Tae-woo.
Japan Standard Time (日本標準時, Nihon Hyōjunji; JST), or Japan Central Standard Time (中央標準時, Chūō Hyōjunji; JCST), is the standard time zone in Japan, 9 hours ahead of UTC (UTC+09:00). Japan does not observe daylight saving time, though its introduction has been debated on several occasions. During World War II, the time zone was often referred to as Tokyo Standard Time.
Japan Standard Time is equivalent to Korean Standard Time, Pyongyang Time (North Korea), Eastern Indonesia Standard Time, East-Timorese Standard Time, Palau Time, and Yakutsk Time (Russia).
Operation Pokpung (Korean: 폭풍 작전, lit. ''Operation Storm'') was the invasion of South Korea (Republic of Korea, ROK) by North Korea (Democratic People's Republic of Korea, DPRK) that triggered the Korean War. North Korea launched the blitzkrieg by crossing the 38th parallel north and swarming South Korea at 04:00 PYT/KST on 25 June 1950. The DPRK did not declare war before the invasion and rushed to encircle and eventually capture Seoul, the capital of South Korea, from the ROK within a week.
North Korea had mobilized for an invasion of South Korea for over year prior with support from the Soviet Union, which trained and supplied the Korean People's Army (KPA) with weapons, munitions, armored fighting vehicles, tanks, and aircraft. The vastly superiorly armed and trained KPA overwhelmed and overran the ill-prepared and underarmed Republic of Korea Army (ROKA); thus the DPRK captured Seoul within three days on 28 June.
Timor-Leste uses UTC+09:00. In the west the country borders the UTC+08:00 zone of Central Indonesia and in the east the UTC+09:00 zone of Eastern Indonesia. Daylight saving time is never observed in Timor-Leste, due to its proximity to the equator; there is only a small variation between the length of day and night throughout the year. Timor-Leste shares the same time zone with Japan Standard Time, Korean Standard Time, Pyongyang Time (North Korea), Eastern Indonesia Standard Time, Palau Time, and Yakutsk Time (Russia).
Time in Palau is given by Palau Time (PWT; UTC+09:00). Palau does not have an associated daylight saving time.
Palau Time is equivalent to Japan Standard Time, Korean Standard Time, Pyongyang Time (North Korea), Eastern Indonesia Standard Time, East-Timorese Standard Time, and Yakutsk Time (Russia).
