Autoloading Time Library

Hello, I'm new to CI4 and didn't quite understand how can I autoload and use Time library.  
codeigniter.com/user_guide/libraries/time.html

I tried to load it via BaseController with using:

Code:

use CodeIgniter\I18n\Time;

$this->time = new Time();

But it didn't work. Can someone explain? I want to autoload it and use in the views.
