About Australia/Hobart
Australia/Hobart is the IANA time zone for Tasmania in Australia. It currently keeps Australian Eastern Standard Time (AEST, UTC+10) in winter and Australian Eastern Daylight Time (AEDT, UTC+11) in summer.
Its principal location is Hobart at 42.88° S, 147.32° E.
Abbreviations in use: AEST, AEDT. Offset page: UTC+10.
Rule for future years (POSIX TZ string)
AEST-10AEDT,M10.1.0,M4.1.0/3
The standard time is called AEST and is UTC+10. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "-10". Daylight saving time is called AEDT and is UTC+11. It starts on the first Sunday of October at 02:00 and ends on the first Sunday of April at 03:00, local time. Software that has no full tzdata copy, such as many embedded devices, can use this string directly as the TZ environment variable.

Convert Hobart time
Using Australia/Hobart in code
Every major platform reads the same IANA ID. Store instants in UTC and convert with the ID at display time; never store a fixed offset for a place that has daylight saving time.
