Why does the browser show the wrong cookie expiration time (made cookies through the js-cookie library)?

Question

JavaScript

Through js-cookie I set a cookie which expires after 1 day. Here is the code:
Cookies.set('asd', true, {expires: 1})

Next, I went to the Google Chrome developer console, there in Application, on the left I selected Cookies. Clicked on the site's domain and found the cookie I set (named asd). And in his Expiries / Max-Age it is written:
2021-06-11T17:41:35.000Z

As I understand it, the date comes first in the year-month-day format. Then the letter T and the time in the format hour:minute:second. Then a dot and some value.
If so, then the time is set incorrectly. I have 20 hours on my watch. And in cookies 17.

I thought that cookies depend on the server time. And the time is set incorrectly on the server. I wrote this code in php:

<?php
$date = date('m/d/Y H:i:s', time());
echo $date;

He brought out the time that I have on the clock. No 3 hours late. And in cookies late.

Why is this happening?
