About Pacific/Pago_Pago
Pacific/Pago_Pago is the IANA time zone for Midway in American Samoa and United States Minor Outlying Islands. It currently keeps American Samoa Time (SST, UTC−11) all year.
The zone serves 2 countries or territories because their clocks have agreed since 1970; tzdata lists them together in zone1970.tab. That says nothing about borders or sovereignty, as the file’s header points out.
Its principal location is Pago Pago at 14.27° S, 170.70° W.
Abbreviations in use: SST. Offset page: UTC−11.
Rule for future years (POSIX TZ string)
SST11
The standard time is called SST and is UTC−11. POSIX writes the offset with the opposite sign (west of Greenwich is positive), which is why the string says "11". 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 Pacific/Pago_Pago since 1970
The record starts with local mean time (UTC+12:37), which ended on July 4, 1892. The record shows no daylight saving time at any point.
