About daylight saving
These abbreviations name a zone, not a fixed offset. IST is Asia/Kolkata and is currently on GMT+5:30; MST is America/Denver and is currently on MDT. 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.
