Bug #78309 [NEW]: error_log date output default timezone overrides date.timezone

From: ian dot lintner at workiva dot com Operating system: aws-linux, alpine PHP version: 7.3.7 Package: *General Issues Bug Type: Bug Bug description:error_log date output default timezone overrides date.timezone Description: ------------ error_log emitted log entry timezone appears to be using the "Default Timezone" first and before falling back to date.timezone rather than just using date.timezone as the overriding variable. So this maybe the expected behavior now, but the last error_log bugfix notes that I read the goal was to use date.timezone only, but there maybe superseding requirements that I missed or this is a feature request or documentation update. After reading tracing the PHP source it appears error_log uses the user function: php_format_date Source: https://github.com/php/php-src/blob/3c2f433b2b0a4334b4f96358660ead92abdbb2cb/main/main.c#L888 Which uses guess timezone, which follows the fallback logic of * "Default Timezone" * date.timezone * UTC (I maybe wrong) The concern is in a web application where users may specify their default Timezone (e.g. Drupal) then error_log entries can have different timezones. Personally opinion date.timezone should be the timezone for error_log as it is an ini value rather than a mutable value that may change between session, request or execution. So the error log timezone can remain consistent across multiple servers, executions. just my $.02 -- Edit bug report at https://bugs.php.net/bug.php?id=78309&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=78309&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=78309&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=78309&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=78309&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78309&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78309&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78309&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78309&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78309&r=support Expected behavior: https://bugs.php.net/fix.php?id=78309&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78309&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78309&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78309&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=78309&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=78309&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78309&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78309&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78309&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78309&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78309&r=mysqlcfg
