Bug #65787 [NEW]: DateTime::__construct() accepts all single letters except 'j' as valid timezone

From: vascowhite at gmail dot com Operating system: All? PHP version: 5.5.4 Package: Date/time related Bug Type: Bug Bug description:DateTime::__construct() accepts all single letters except 'j' as valid timezone Description: ------------ If just a single letter is passed to the constructor of \DateTime it is accepted as a valid timezone string. Except, for some strange reason, the letter 'j'. Test script: --------------- $date = new \DateTime('a'); var_dump($date); Expected result: ---------------- I expect an exception to be raised with the message:- Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct(): Failed to parse time string (a) at position 0 (a): The timezone could not be found in the database' Actual result: -------------- Except for when the letter 'j' is passed a DateTime object is created. For example the following code:- $date = new \DateTime('a'); var_dump($date); Will give the following output:- object(DateTime)[1] public 'date' => string '2013-09-29 15:17:19' (length=19) public 'timezone_type' => int 2 public 'timezone' => string 'A' (length=1) Where it should raise an exception. -- Edit bug report at https://bugs.php.net/bug.php?id=65787&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65787&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65787&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65787&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65787&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65787&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65787&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65787&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65787&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65787&r=support Expected behavior: https://bugs.php.net/fix.php?id=65787&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65787&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65787&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65787&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65787&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65787&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65787&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65787&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65787&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65787&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65787&r=mysqlcfg
