    <?php
use Cake\I18n\FrozenDate;
    ?>

    <?= date_default_timezone_get() ?>
    <?php $time1 = FrozenDate::create($year, $month, 1)->timestamp ?>
    <?= $time1 ?>
    <?= FrozenDate::createFromTimestamp($time1) ?>

    <?php date_default_timezone_set('Europe/Paris') ?>
    <?php $time3 = FrozenDate::create($year, $month, 1)->timestamp ?>
    <?= date('Y-m-d 00:00:00', $time3) ?>
    <?= $time3 ?>
    <?= FrozenDate::createFromTimestamp($time3) ?>

Gives:

    UTC 
    1454284800 
    01/02/2016 

    2016-02-01 00:00:00 
    1454284800 
    31/01/2016

but if im using

<?= new FrozenDate($time3) ?>

it gives correct result also while switching to \I18n\Date gives me

UTC 
1454284800 
01/01/1970 

2016-02-01 00:00:00 
1454284800 
01/01/1970

and again using

<?= new Date($time3) ?>

gives correct results

@markstory reminder "I bet I missed 'correcting' createFromTimestamp() then :)"

I'll take a look. This might be an issue in cakephp/chronos.
