DatePicker does not display the date in input when editing

//Set new date

this.state.startDate = new Date("July 27, 1962 23:30:00")
const date = new Date(this.state.startDate);

//Set hours

date.setHours(0, 0, this.state.second);
date.toTimeString();

When I click edit. I want this date to be displayed in the input. And that it can be edited

    const date = new Date(this.state.startDate);
    console.log(date)
