Be careful when using two numbers as the year. I came across this situation:
<?php
echo strtotime('24.11.22');
echo date('d.m.Y H:i:s', 1669324282) . "\n\n";
// But
echo strtotime('24.11.2022');
echo date('d.m.Y H:i:s', 1669237200);
?>
Output:
1669324282
25.11.2022 00:11:22
1669237200
24.11.2022 00:00:00
