How to click a button at a specific time?

Question

Google Chrome

Hello, how can I set a command in the browser console so that a button is pressed on the site at a certain time (up to a second)?

Answer 1

You can get the time difference between then and now and set this time period to a timer. As soon as this time passes, the function will be executed.

// Точное время, когда выполнить команду
var whenDate = new Date(2020, 5, 28, 9, 0, 0, 0); // 28 июня 2020 г. 09:00:00.000 (9 утра)
// Точное время сейчас
var nowDate = new Date();

// Ставим таймер, который нажмёт на зелёную кнопку
// на сайте Тостер "Задать вопрос" ровно в 9 утра.
setTimeout(function() {
    document.querySelector(".btn_add-question").click()
}, whenDate-nowDate);

Is it possible to somehow make it so that the time the button was pressed is simply indicated? Without present time
