What JST and PST mean here

JST (Japan Standard Time) is UTC+9 all year; Japan doesn't use daylight saving time. Tokyo and Osaka are on the same clock. Korea (KST) has the same offset, so the result is also right for Seoul.

PST means US Pacific Time: Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver. That's PST (UTC−8) in winter and PDT (UTC−7) from March 8 to November 1, 2026. The Philippines also uses "PST" for Philippine Standard Time (UTC+8); for that, search for Manila.
