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();
?>
