The timestamp is always UTC and the DateTime constructor using the timestamp assumes UTC.  Thus you cannot roundtrip the timestamp without adjusting for the local time zone.  Consider the following code...

$d0 = new \DateTime();
echo json_encode($d0).'<br>';
echo 'timestamp = '.$d0->getTimestamp().'<br>';
$d1 = new \DateTime('@'.$d0->getTimestamp());
echo json_encode($d1).'<br>';

This code will produce (with server time zone set to MST)

"date":"2022-09-26 10:26:34.864244","timezone_type":3,"timezone":"America\/Phoenix"}
timestamp = 1664213194
{"date":"2022-09-26 17:26:34.000000","timezone_type":1,"timezone":"+00:00"}
