About these time zones
Japan Standard Time (JST)
Japan Standard Time (JST) is UTC+9 all year across the whole of Japan. Japan has not observed daylight saving time since 1951. JST shares its offset with Korea Standard Time.
India Standard Time (IST)
India Standard Time (IST) is UTC+5:30 and is used across all of India as a single time zone. India does not observe daylight saving time, so IST never changes — but its difference from places that do (like US Eastern Time) changes twice a year.
