Time diff NOT WORKING

Cannot reproduce.
PHP 8.2.16
PHP 7.4.33

PHP Code:

$date1 = new Time("2024-03-31");
$date2 = new Time("2024-04-01");

echo $date1->difference($date2)->days;  // 1 


Thank you for your reply; you are right, if I set up a brand new install of CI 4.4.6, no database setup, and put that code in the welcome_page view and IT WORKS (shows "1")

However, when I edit the app\Config\App.php file and change it for SPANISH LOCALE it STOPS WORKING for this example (shows "0")!

These are the lines changed in my App.php file:

PHP Code:

public string $defaultLocale = 'es';
public array $supportedLocales = ['es'];
public string $appTimezone = 'Europe/Madrid'; 


After some testing I've noticed that it is specifically the third line ($appTimezone) that is causing the error (if I change it back to UTC, the method throws "1" again!). It is a very strange behaviour because other date combinations do work with the modified App.php file, and according to the link included in that file just above the $appTimezone setting (https://www.php.net/manual/en/timezones.php), the string I'm using for the time zone should be valid.

The problem appears with any "Europe/X" city that I've tried (Amsterdam, Paris...)

Many thanks!
