About Adelaide's Time Zone
Adelaide, the capital of the Australian state of South Australia, sits in the country's only time zone with a rare 30-minute offset.
South Australia observes daylight saving on the same calendar as Sydney, so Adelaide stays a constant half hour behind it year-round — but its gap with non-DST Perth shifts between 1.5 and 2.5 hours depending on the season.
