[YuanchengJiang]

Description

The following code:

<?php
define("MAX_64Bit", 9223372036854775807);
define("MIN_64Bit", -9223372036854775807 - 1);
$longVals = array(
MAX_64Bit -1, MAX_64Bit + 1, MIN_64Bit + 1, MIN_64Bit - 1
);
foreach ($longVals as $longVal) {
}
$fusion = $longVal;
$d1 = new DateTime('now',new DateTimeZone('Europe/Paris'));
$d2 = new DateTime('now',new DateTimeZone('Europe/Paris'));
$d1->setTimestamp($fusion);
$diff = $d1->diff($d2);

Resulted in this output:

runtime error: signed integer overflow: 1731482775 - -9223372036854775808 cannot be represented in type 'long long'

The issue occurs on the timelib dependency however at the moment timelib has no way to handle it without changing its internals, do not know the best way between catching it early in date_diff method and/or fixing/updating timelib.
