Pacific Standard Time is the time of the Western United States and Canada and is typically abbreviated as PST. It is 8 hours behind GMT. This means that when the clock is noon in London (GMT), it is 4AM in Seattle (PST).
Most of the Western US and Canada are following Pacific Standard Time.
This can be a bit tricky as most states on the US Pacific Coast do apply daylight saving time, calling PST for PDT, or Pacific Daylight Time, instead and sets the clocks in November and March respectively.
Korean Standard Time, or KST for short, is the standard time zone for South Korea. It is 9 hours ahead of UTC. North Korea was on KST until 2015 when they introduced their own Pyongyang Standard Time, which is 30 minutes behind Korean Standard Time.
South Korea is the only country using Korean Standard Time. It is however the same time as JST – Japan Standard Time and AWDT – Australian Western Daylight Time (i.e. when Western Australia applies Daylight Saving Time). As noted above, North Korea are since 2015 using their own time zone.
All cities in Korea applies KST, including Seoul, Busan, Incheon, Daegu, Daejeon, Suwon and Gwangju.
DST (Daylight Saving Time) is currently not applied in South Korea, although there were experiments during the 1988 Olympics.
