Datetime(CreateFromTimestamp/CreateFromFromat(U)) - no timezone

[dwalck]

Description

The following code:

<?php

 echo date_default_timezone_get();
 echo PHP_EOL;

$dt = new \DateTimeImmutable();
echo $dt->getTimezone()->getName();
echo PHP_EOL;

$dt1 = new \DateTimeImmutable()->setTimestamp(1742892008);
echo $dt1->getTimezone()->getName();
echo PHP_EOL;

$dt2 = \DateTimeImmutable::createFromTimestamp(1742892008);
echo $dt2->getTimezone()->getName();
echo PHP_EOL;

$dt3 = \DateTimeImmutable::createFromFormat('U', '1742892008');
echo $dt3->getTimezone()->getName();
echo PHP_EOL;

Resulted in this output:

UTCUTCUTC
+00:00
+00:00

But I expected this output instead:

UTCUTCUTC
UTC
UTC

PHP Version

8.4.5

Operating System

No response

CreateFromFormat with non-timestamp value seems to working properly:

\DateTimeImmutable::createFromFormat('H:i:s d.m.Y', '09:30:00 25.03.2025') 

will create object with valid timezone.
