Bug #66985 [Nab]: Some timezones are no longer valid in PHP 5.5.10

Edit report at https://bugs.php.net/bug.php?id=66985&edit=1 ID: 66985 User updated by: evert at rooftopsolutions dot nl Reported by: evert at rooftopsolutions dot nl Summary: Some timezones are no longer valid in PHP 5.5.10 Status: Not a bug Type: Bug Package: Date/time related Operating System: Any PHP Version: 5.5.10 Block user comment: N Private report: N New Comment: Hey Derick, They worked, because they are part of the olson file, and they are documented on the php site: https://php.net/manual/en/timezones.others.php Furthermore, I'm using these, not in my code, but because I'm receiving timezone strings from various sources that I can't control. This one came from a c library (libical) from some system that had it's system timezone likely set to EST5EDT. While I don't disagree that neither I nor anyone else should be using these, you introduced a BC break in a minor PHP version of a documented feature, without as much as a mention in the changelog. That, to me, sounds like a bug. Previous Comments: ------------------------------------------------------------------------ [2014-03-31 10:00:46] derick@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. You're right. Those no longer work. But you're also right that you used a "feature" that you shouldn't have. Those names are not "timezones", but rather country names (or weird BC entries). It surprises me that they worked in the first place! ------------------------------------------------------------------------ [2014-03-30 22:25:47] evert at rooftopsolutions dot nl Here's a full list of timezones that are not supported on PHP 5.5.10: CST6CDT Cuba Egypt Eire EST5EDT Factory GB-Eire GMT0 Greenwich Hongkong Iceland Iran Israel Jamaica Japan Kwajalein Libya MST7MDT Navajo NZ-CHAT Poland Portugal PST8PDT Singapore Turkey Universal W-SU ------------------------------------------------------------------------ [2014-03-30 20:13:50] evert at rooftopsolutions dot nl Description: ------------ Sample code attached. Note that this worked before 5.5.10. Perhaps I took advantage of a feature that was not supposed to be supported, in which case I would definitely appreciate a workaround that works pre and post 5.5.10 :) Test script: --------------- php -r "echo (new DateTimeZone('EST5EDT'))->getName();"; Expected result: ---------------- EST5EDT Actual result: -------------- Fatal error: Uncaught exception 'Exception' with message 'DateTimeZone::__construct(): Unknown or bad timezone (EST5EDT)' in Command line code on line 1 Exception: DateTimeZone::__construct(): Unknown or bad timezone (EST5EDT) in Command line code on line 1 Call Stack: 0.0001 221064 1. {main}() Command line code:0 0.0001 221296 2.
