About these two clocks
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).
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.
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 America/Los_Angeles and Asia/Kolkata explicitly.
