Temporal.PlainDateTime.prototype.nanosecond

The nanosecond accessor property of {{jsxref("Temporal.PlainDateTime")}} 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 {{jsxref("Temporal/PlainDateTime/with", "with()")}} method to create a new Temporal.PlainDateTime object with the desired new value.

For general information and more examples, see {{jsxref("Temporal/PlainTime/nanosecond", "Temporal.PlainTime.prototype.nanosecond")}}.
