Time diff NOT WORKING

Hello,

PHP 8.2.12
CodeIgniter v 4.4.6

PHP Code:

use \CodeIgniter\I18n\Time;

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

echo $date1->difference($date2)->days;  // 0 !!!

// the native PHP classes work fine:

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

echo $date1->diff($date2)->format("%a");  // 1 


What is most strange: it actually works well for most other dates, I can't find why but this behavior makes this function useless...

many thanks for this excelent framework!
