It's hard to reproduce because I'm working on Symfony. My DateTimeImmutable has
date.timezone_type = 1
date.timezone = "+00:00"
But here is a more accuracte sample of what is my "state" when the bug occures :
$timeZoneTl = IntlTimeZone::createTimeZone('Europe/Paris')->toDateTimeZone();
$dateT = DateTimeImmutable::createFromFormat('Y-m-d H:i:s', '1940-06-13
22:00:00', new DateTimeZone('Etc/GMT-0'));
$timeZonedDateT = $dateT->setTimezone($timeZoneTl);
echo $timeZonedDateT->format('Y-m-d');
Output : 13/06/1940 (wrong)
$timeZoneTl = IntlTimeZone::createTimeZone('Europe/Paris')->toDateTimeZone();
$dateT = DateTimeImmutable::createFromFormat('Y-m-d H:i:s', '1940-06-15
22:00:00', new DateTimeZone('Etc/GMT-0'));
$timeZonedDateT = $dateT->setTimezone($timeZoneTl);
echo $timeZonedDateT->format('Y-m-d');
Output : 15/06/1940 (correct)
