Time zone reference
Adelaide
Australia/Adelaide is an IANA time-zone identifier currently displaying an offset of UTC+09:30 and the abbreviation ACST. Daylight-saving time is not active at the profile generation time. The next detected offset transition is 2026-10-04T05:49:30+10:30. Civil-time rules can change after government announcements, and historical coverage is less complete before 1970; applications should use an updated tzdb release rather than hard-coded offsets.
