Tracking issue for the Temporal builtin · Issue #1804 · boa-dev/boa (original) (raw)

Tracking for the Temporal built-in implementation

ECMASCript feature
The new Temporal API has been introduced to improve date handling in JavaScript, and we should add it to Boa to be up to date with the current ECMAScript standard. Tests have been added to the official ECMAScript Test Suite (test262), so we need to pass these tests to get full coverage.

The current proposal (Stage 3) specification can be found here: https://tc39.es/proposal-temporal/

In order to implement this new proposal, you can follow the example of other builtin objects, and feel free to ask for help: https://github.com/boa-dev/boa/tree/main/boa/src/builtins

Example code

This code should now work and give the expected result:

// exact time since the Unix epoch on 1 Janary, 1970 UTC Temporal.now.instant(); Temporal.now.instant().epochSeconds; Temporal.now.instant().epochMilliseconds;

// current time zone Temporal.now.timeZone();

// time in current location, e.g. // 2021-09-18T04:17:48.435068431-04:00[America/New_York] Temporal.now.zonedDateTimeISO();

// time in another time zone, e.g. // 2021-09-18T09:17:48.438068435+01:00[Europe/London] Temporal.now.zonedDateTimeISO('Europe/London');
