javascript instance accessor property
Temporal.PlainTime.prototype.nanosecond
The nanosecond accessor property of PlainTime instances returns an integer from 0 to 999 representing the nanosecond (10-9 second) component of this time.
The set accessor of nanosecond is undefined. You cannot change this property directly. Use the with() method to create a new Temporal.PlainTime object with the desired new value.
Examples
Using nanosecond
const time = Temporal.PlainTime.from("12:34:56");
console.log(time.nanosecond); // 0
const time2 = Temporal.PlainTime.from("12:34:56.123456789");
console.log(time2.nanosecond); // 789
Changing nanosecond
const time = Temporal.PlainTime.from("12:34:56");
const newTime = time.with({ nanosecond: 100 });
console.log(newTime.toString()); // 12:34:56.0000001
You can also use add() or subtract() to move a certain number of nanoseconds from the current time.
const time = Temporal.PlainTime.from("12:34:56");
const newTime = time.add({ nanoseconds: 100 });
console.log(newTime.toString()); // 12:34:56.0000001
