It's important to note that on 32-Bit systems getTimestamp() will return false for dates greater than 2038, while format("U") will return an unsigned integer



This will return false:



<?php

    $dt = new DateTime('2039/1/1');

    echo  $dt->getTimestamp();

?>



But this will return a value:



<?php

    $dt = new DateTime('2039/1/1');

    echo  $dt->format('U');

?>

Note that for dates before the unix epoch getTimestamp() will return false, whereas format("U") will return a negative number.



<?php

$date = new DateTime("1899-12-31");

// "-2209078800"

echo $date->format("U");

// false

echo $date->getTimestamp();

?>
