Using this identifier

The string to put in your code.

Pacific/Pago_Pago is the identifier to use in code and config for this region. Every modern language, database, and OS resolves it through the same tz database, so the examples here behave identically everywhere.

Avoid storing SST or -11:00 — abbreviations are ambiguous and fixed offsets can't follow rule changes.

// format a date in this zone
new Intl.DateTimeFormat('en-US', {
timeZone: 'Pacific/Pago_Pago',
dateStyle: 'full', timeStyle: 'long'
}).format(new Date());
