The Temporal.Instant() constructor creates Temporal.Instant objects.
This constructor is exactly equivalent to calling Temporal.Instant.fromEpochNanoseconds().
Syntax
js
new Temporal.Instant(epochNanoseconds)
Parameters
epochNanoseconds-
A BigInt representing the number of nanoseconds since the Unix epoch.
Return value
A new Temporal.Instant object representing the instant in time specified by epochNanoseconds.
Exceptions
RangeError-
Thrown if
epochNanosecondsrepresents an instant outside the range of representable instants, which is ±108 days, or about ±273,972.6 years, from the Unix epoch.
Examples
Using Temporal.Instant()
js
const instant = new Temporal.Instant(0n);
console.log(instant.toString()); // 1970-01-01T00:00:00Z
const vostok1Liftoff = new Temporal.Instant(-275248380000000000n);
console.log(vostok1Liftoff.toString()); // 1961-04-12T06:07:00Z
const sts1Liftoff = new Temporal.Instant(355924804000000000n);
console.log(sts1Liftoff.toString()); // 1981-04-12T12:00:04Z
