About these time zones
Australian Eastern Standard Time (AEST)
Australian Eastern Standard Time (AEST) is UTC+10. New South Wales, Victoria, Tasmania and the ACT use AEST in winter and Australian Eastern Daylight Time (AEDT, UTC+11) from the first Sunday in October to the first Sunday in April. Queensland stays on AEST all year.
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.
