The millisecond accessor property of Temporal.PlainTime instances returns an integer from 0 to 999 representing the millisecond (10^-3 second) component of this time.

The set accessor of millisecond 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 millisecond

const time = Temporal.PlainTime.from("12:34:56");
console.log(time.millisecond); // 0

const time2 = Temporal.PlainTime.from("12:34:56.123456789");
console.log(time2.millisecond); // 123

Changing millisecond

const time = Temporal.PlainTime.from("12:34:56");
const newTime = time.with({ millisecond: 100 });
console.log(newTime.toString()); // 12:34:56.1

You can also use add() or subtract() to move a certain number of milliseconds from the current time.

const time = Temporal.PlainTime.from("12:34:56");
const newTime = time.add({ milliseconds: 100 });
console.log(newTime.toString()); // 12:34:56.1
