About the two zones
Sydney. Sydney is on AEST (UTC+10) in winter and AEDT (UTC+11) in summer. Because it is in the southern hemisphere, its summer time runs from October to April, the opposite of Europe and North America.
India. India uses a single time zone, UTC+5:30, all year. It does not observe daylight saving, so the gap to zones that do changes twice a year.
