About these two clocks

SGT — Singapore Time. Used in Singapore (Kuala Lumpur shares the offset). Singapore has no daylight saving time; it is UTC+8 all year.

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 Asia/Singapore and Asia/Kolkata explicitly.
