Adelaide Time uses the IANA identifier Australia/Adelaide. The current snapshot on Oct 16, 2026 shows UTC+10:30 and the abbreviation ACDT; daylight-saving time is Active. These values describe the selected moment, not a fixed rule for every date. Governments can change civil-time rules, and the IANA database records historical and scheduled changes for a location. For appointments, travel, software logs, and international deadlines, keep the named zone together with the date instead of saving only an abbreviation or UTC offset. A label such as CST may refer to more than one region, while Australia/Adelaide gives the calculator a specific rule set.
UTC-to-local reference for today
