About these two clocks
IST — India Standard Time. Used in all of India — Mumbai, Delhi, Bengaluru. India does not use daylight saving time, so IST is UTC+5:30 all year.
PST — Pacific Time. Used in Los Angeles, San Francisco, Seattle, Vancouver. PST is the winter name; from March to November the same clocks show PDT (UTC−7).
All figures on this page come from the IANA time zone database (the same data your phone and laptop use), evaluated for the date in question. Abbreviations are ambiguous — “IST” also means Irish or Israel Standard Time, and “CST” is China Standard Time in Asia — so this page uses Asia/Kolkata and America/Los_Angeles explicitly.
