#35660 [Opn]: AIX TZ variable format not understood, yields UTC timezone

ID: 35660 User updated by: Bjorn dot Wiberg at its dot uu dot se Reported By: Bjorn dot Wiberg at its dot uu dot se Status: Open -Bug Type: Feature/Change Request +Bug Type: Date/time related Operating System: AIX 5.2.0.0 ML5 PHP Version: 5.1.1 New Comment: Just a quick note to tell that PHP does log this fact in the Apache error log: PHP Notice: date(): Timezone setting (date.timezone) or TZ environment variable contains an unknown timezone in /apache/htdocs/... Previous Comments: ------------------------------------------------------------------------ [2005-12-13 19:28:32] Bjorn dot Wiberg at its dot uu dot se Description: ------------ PHP does not understand the notion of the TZ environment variable that IBM AIX uses, and defaults to the UTC time zone if an "incorrect" TZ value is encountered. The format of the TZ variable, and the allowed values, can be found here: http://publib.boulder.ibm.com/infocenter/pseries/index.jsp?topic=/com.ibm.aix.doc/files/aixfiles/environment.htm If this could be considered for future releases, that would be a great relief. As many (all?) other software on the system seem to use the TZ correctly. Otherwise, it would be great if the date.timezone setting would act as a fallback in case the TZ environment variable is considered invalid by PHP. And, perhaps, that this is clarified in the documentation (http://se.php.net/manual/sv/function.date-default-timezone-get.php); i.e., that an incorrect TZ value directly yields a "UTC" timezone setting. Reproduce code: --------------- System environment configuration file /etc/environment contains: TZ=NFT-1DFT,M3.5.0/02:00:00,M10.5.0/03:00:00 httpd.conf contains: php_value date.timezone "Europe/Stockholm" PHP script that displays the reverting-to-UTC behavior of PHP: <?php // putenv('TZ=NFT-1DFT,M3.5.0/02:00:00,M10.5.0/03:00:00'); echo 'TZ is: ' . getenv('TZ') . '<BR>'; echo 'date.timezone is: ' . ini_get('date.timezone') . '<BR>'; echo 'date_default_timezone_get() returns: ' . date_default_timezone_get() . '<BR>'; echo 'Current time is: ' . strftime('%T') . '<BR>'; echo '<BR>'; echo 'Forcing the correct timezone (' . ini_get('date.timezone') . ')...<BR>'; date_default_timezone_set(ini_get('date.timezone')); echo 'Correct current time is: ' . strftime('%T') . '<BR>'; ?> Expected result: ---------------- That the timezone is picked up and understood by PHP. This would equal the "Europe/Stockholm" timezone setting. That is: TZ is: NFT-1DFT,M3.5.0/02:00:00,M10.5.0/03:00:00 date.timezone is: Europe/Stockholm date_default_timezone_get() returns: Europe/Stockholm Current time is: 19:20:10 Forcing the correct timezone (Europe/Stockholm)... Correct current time is: 19:20:10 Actual result: -------------- TZ is: NFT-1DFT,M3.5.0/02:00:00,M10.5.0/03:00:00 date.timezone is: Europe/Stockholm date_default_timezone_get() returns: UTC Current time is: 18:20:10 Forcing the correct timezone (Europe/Stockholm)... Correct current time is: 19:20:10 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35660&edit=1
