About these two clocks

CET — Central European Time. Used in Berlin, Paris, Madrid, Rome, Amsterdam. CET is the winter name; from late March to late October the same clocks show CEST (UTC+2).

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 Europe/Berlin and Asia/Kolkata explicitly.
