== Describing The Problem ==
When using the static method DateTime::createFromFormat() or the new
DateTime()
constructor to create a DateTime object instance from a Unix Timestamp, the
resulting date can be one day out, even though the timestamp is not. To
reproduce the bug, run the test script below.
Test script:
---------------
<?php
// Bad
$d=DateTime::createFromFormat("!Y-m-d H:i:s", "2012-11-30 00:00:00");
echo $d->getTimestamp() . PHP_EOL;
echo $d->format("Y-m-d") . PHP_EOL;
$e=new DateTime("@". $d->getTimestamp());
echo $e->getTimestamp() . PHP_EOL;
echo $e->format("Y-m-d") . PHP_EOL . PHP_EOL;
/*
1354194000
2012-11-30
1354194000
2012-11-29
*/
// Bad
$d=DateTime::createFromFormat("!Y-m-d H:i:s", "2012-11-30 00:00:00");
echo $d->getTimestamp() . PHP_EOL;
echo $d->format("Y-m-d") . PHP_EOL;
$e=DateTime::createFromFormat("U", $d->getTimestamp());
echo $e->getTimestamp() . PHP_EOL;
echo $e->format("Y-m-d") . PHP_EOL . PHP_EOL;
/*
1354194000
2012-11-30
1354194000
2012-11-29
*/
// Good
$d=DateTime::createFromFormat("!Y-m-d H:i:s", "2012-11-30 00:00:00");
echo $d->getTimestamp() . PHP_EOL;
echo $d->format("Y-m-d") . PHP_EOL;
$e=new DateTime();
$e->setTimestamp($d->getTimestamp());
echo $e->getTimestamp() . PHP_EOL;
echo $e->format("Y-m-d") . PHP_EOL;
/*
1354194000
2012-11-30
1354194000
2012-11-30
*/
Expected result:
----------------
1354194000
2012-11-30
1354194000
2012-11-30
1354194000
2012-11-30
1354194000
2012-11-30
1354194000
2012-11-30
1354194000
2012-11-30
Actual result:
--------------
1354194000
2012-11-30
1354194000
2012-11-29
1354194000
2012-11-30
1354194000
2012-11-29
