About daylight saving
These abbreviations name a zone, not a fixed offset. JST is Asia/Tokyo and is currently on GMT+9; CST is America/Chicago and is currently on CDT. The gap between them changes on the days each side switches, which is why this page converts through the zones rather than through a stored offset.
