PHP DateTime unable to parse time string from epoch timestamp

Question

I am trying to display the number in hours since a date like this...

$timestamp1 = '1517158402';
$timestamp2 = '1530204802';
$timestamp3 = '1548694384';

if ($timestamp1 && $timestamp2 && $timestamp3 ) {

    /* Calculate time */
    $timestamp1_obj = new DateTime($timestamp1);
    $timestamp2_obj = new DateTime($timestamp2);
    $timestamp3_obj = new DateTime($timestamp3);

    $since_start = $timestamp2_obj->diff($timestamp3_obj);
    echo $since_start->h.' hours';

}

This is giving me the error message...

Uncaught Exception: DateTime::__construct(): Failed to parse time string

Anyone any ideas where I am going wrong?

DateTime::__construct() expects a string with one of the formats listed here — aynber

You can also use new DateTime(date('Y-m-d H:i:s', $timestamp1)); — aynber

You need to use setTimestamp.

$date = new DateTime();
$date->setTimestamp(1171502725);

Thank you, setTimestamp was exactly what was missing!
