Description:
------------
When DateTime::createFromFormat('U', strtotime('1962-11-17T00:00:00+00:00') is executed the result is false as strtotime('1962-11-17T00:00:00+00:00') is negative.
Using date function with the same input works OK
Test script:
---------------
echo date('YmdHis', strtotime('1962-11-17T00:00:00+00:00')); // 19621117000000
print_r(DateTime::createFromFormat('U', strtotime('1962-11-17T00:00:00+00:00'), new \DateTimeZone('UTC'))->format('YmdHis')); // fails as createFromFormat returns false

I can confirm that the issue is solved in PHP-7.0 and master, but not in PHP-5.6, as the following PHPT fails there: --TEST-- Bug #66836 (DateTime::createFromFormat 'U' with pre 1970 dates fails parsing) --FILE-- <?php $timestamp = '-1'; $dt = DateTime::createFromFormat('U', $timestamp); var_dump($dt->format('U') === $timestamp); ?> --EXPECT-- bool(true)@cmb, I can't reproduce that: [GIT: PHP-5.6][PHP: 5.6.20-dev ] derick@whisky:~/dev/php/php-src.git $ php <?php $timestamp = '-1'; $dt = DateTime::createFromFormat('U', $timestamp); var_dump($dt, $dt->format('U'), $timestamp); ?> But fixed in .25-dev: [GIT: PHP-5.6][PHP: 5.6.25-dev ] derick@whisky:~/dev/php/php-src.git $ php <?php $timestamp = '-1'; $dt = DateTime::createFromFormat('U', $timestamp); var_dump($dt, $dt->format('U'), $timestamp); ?> -:4: class DateTime#1 (3) { public $date => string(26) "1969-12-31 23:59:59.000000" public $timezone_type => int(1) public $timezone => string(6) "+00:00" } -:4: string(2) "-1" -:4: string(2) "-1"
