Comment (by autotutorial):

 Do not choose UTC+0 but UTC this time zone cannot be evaluated for
 daylight saving time or Standard time. (Only Universal Cordinated Time).
 Europe/Rome Daylight saving time Output UTC 2020-03-29 02:00:00
 Europeo/Rome Standard time OUTPUT 2020-10-25 03:00:00.
 This is the only case of using arithmetic operations otherwise it creates
 confusion because it can be thought to be referred to before the change of
 Dayligth saving time or Standard time.
 If I don't create a container variable $allowed_zones it is not possible
 to free 1500 KB wp_timezone_choiche + 1500 KB callback wp_timezone_choice
 + 1500 KB options-general.php.
 I am for the opinion of releasing superfluous 5 megabytes but I understand
 other points of view.
