Temporal.Instant.prototype.toZonedDateTimeISO()

The toZonedDateTimeISO() method of Temporal.Instant instances returns a new Temporal.ZonedDateTime object representing this instant in the specified time zone using the ISO 8601 calendar system.

Syntax

toZonedDateTimeISO(timeZone)

Parameters

timeZone

Either a string or a Temporal.ZonedDateTime instance representing the time zone to use. If a Temporal.ZonedDateTime instance, its time zone is used. If a string, it can be a named time zone identifier, an offset time zone identifier, or a date-time string containing a time zone identifier or an offset (see time zones and offsets for more information).

Return value

A new Temporal.ZonedDateTime object representing this instant in the specified time zone using the ISO 8601 calendar system.

Exceptions

RangeError

Thrown if the time zone name is invalid.

TypeError

Thrown if timeZone is not a string or a Temporal.ZonedDateTime instance.

Examples

Using toZonedDateTimeISO()

const instant = Temporal.Instant.from("2021-08-01T12:34:56.123456789Z");
const zonedDateTime = instant.toZonedDateTimeISO("America/New_York");
console.log(zonedDateTime.toString()); // 2021-08-01T08:34:56.123456789-04:00[America/New_York]

const localDateTime = instant.toZonedDateTimeISO(Temporal.Now.timeZoneId());
console.log(localDateTime.toString()); // This instant in your timezone
