About these two clocks
UTC — Coordinated Universal Time. Used in the world reference clock used by servers, aviation and logs. UTC never changes for daylight saving time.
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 UTC and Asia/Kolkata explicitly.
