DateTime::modify returns wrong result

This code should show "2021-03-14 02:00:00" but it shows "2021-03-14 03:00:00":

<?php  $date = new DateTime('2021-03-14 01:45:00');  $date->modify('15 minutes');  echo $date->format('Y-m-d H:i:s');  

Any explanation for this? And more important, any workaround?
