#50520 [Opn->WFx]: fallbackmap.h missing entry for GMT-8 without daylight saving time

ID: 50520 Updated by: derick@php.net Reported By: chikei at gmail dot com -Status: Open +Status: Wont fix Bug Type: Date/time related Operating System: FreeBSD 7.2 PHP Version: 5.3SVN-2009-12-18 (snap) New Comment: This fallback map is there for backwards compatible reasons *only*. From PHP 5.1 onwards you are supposed to make this "date.timezone" setting in php.ini. Relying on the system timezone is *not* going to work properly. Therefore, I am not adding a mapping for UTC+8. Previous Comments: ------------------------------------------------------------------------ [2009-12-18 16:39:39] chikei at gmail dot com Description: ------------ In ext/date/lib/fallbackmap.h you have: { "krat", 0, 7, "Asia/Krasnoyarsk" }, { "krast", 1, 8, "Asia/Krasnoyarsk" }, { "jst", 0, 9, "Asia/Tokyo" }, but lots east Asia region do not use daylight saving time. And in the test server if I use /usr/share/zoneinfo/Etc/GMT-8 as /etc/localtime, I'll get tm_isdat == 0 after a simple localtime_r call, which then resulting PHP think the timezone is UTC. (I removed date.timezone entry in php.ini since i want PHP using OS's timezone setting.) Reproduce code: --------------- Remove date.timezone entry in php.ini and use /usr/share/zoneinfo/Etc/GMT-8 as /etc/localtime, then run date_default_timezone_get() Expected result: ---------------- Should return some timezone rest in GMT-8 region. (such as HongKong or Asia/Vientiane) Actual result: -------------- Returns UTC ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50520&edit=1
