PHP version: 5.2.4
PHP Bug Type: Date/time related
Bug description: Daylight Savings Time Related Problem with Date()
Description:
------------
The date() function is not accurately displaying output expected of dates
during the 1 week long time before daylight savings time, likely because of
the change in the start of daylight savings time from the year prior.
Reproduce code:
---------------
date_default_timezone_set ("America/New_York");
$receiptStamp=mktime(0, 0, 0, 10, 31, 2007);
$modStamp= $receiptStamp + (5 * 24 * 60 * 60); /* Addition of 5 days of
time */
echo date('m/d/Y', $modStamp) . '<br>';
/*
prints 11/04/2007
*/
$dateObject=new DateTime("10/31/2007");
$dateObject->modify("+5 day");
echo date_format( $dateObject, 'm/d/Y' ). '<br>';
/*
prints 11/05/2007
*/
/*After the old daylight savings crossover week*/
$dateObject=new DateTime("11/7/2007");
$dateObject->modify("+5 day");
echo date_format( $dateObject, 'm/d/Y' ). '<br>';
/*
prints 11/12/2007
*/
$receiptStamp=mktime(0, 0, 0, 11, 7, 2007);
$modStamp= $receiptStamp + (5 * 24 * 60 * 60); /* Addition of 5 days of
time */
echo date('m/d/Y', $modStamp). '<br>';
Expected result:
----------------
11/05/2007
11/05/2007
11/12/2007
11/12/2007
Actual result:
--------------
11/04/2007
11/05/2007
11/12/2007
11/12/2007
