The second accessor property of Temporal.PlainDateTime instances returns a integer from 0 to 59 representing the second component of this time.
The set accessor of second is undefined. You cannot change this property directly. Use the with() method to create a new Temporal.PlainDateTime object with the desired new value.
For general information and more examples, see Temporal.PlainTime.prototype.second.
