About Australia/Eucla
Australia/Eucla is the IANA time zone for Western Australia (Eucla) in Australia. It currently keeps UTC+8:45 all year.
Its principal location is Eucla at 31.72° S, 128.87° E.
Rule for future years (POSIX TZ string)
<+0845>-8:45
The standard time is called “+0845” (a numeric abbreviation) and is UTC+8:45. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "-8:45". There is no daylight saving rule: the zone stays on this offset for every year after the end of its explicit transitions. Software that has no full tzdata copy, such as many embedded devices, can use this string directly as the TZ environment variable.
History of Australia/Eucla since 1970
The record starts with local mean time (UTC+8:35), which ended on November 30, 1895. The first daylight saving time in the record is in 1916.

Using Australia/Eucla 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.
