Temporal.ZonedDateTime.prototype.nanosecond

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The nanosecond accessor property of Temporal.ZonedDateTime instances returns a 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.ZonedDateTime object with the desired new value.

For general information and more examples, see Temporal.PlainTime.prototype.nanosecond.
