Edit report at https://bugs.php.net/bug.php?id=76057&edit=1 ID: 76057 Updated by: jhdxr@php.net Reported by: projectcleverweb at gmail dot com Summary: For DateTime the properties 'timezone' and 'timezone_type' are not set on init Status: Open Type: Bug Package: Date/time related Operating System: Linux PHP Version: 7.2.3 Block user comment: N Private report: N New Comment: This behavior (get timezone via property) is not expected, you should use getTimezone() to retrieve timezone. Previous Comments: ------------------------------------------------------------------------ [2018-03-05 21:04:46] projectcleverweb at gmail dot com Description: ------------ In short, these to properties are not set when the class is instantiated, but do become set when the class is serialized OR when the property list is requested (such as via get_object_vars()). You can see the conditions when timezone_type will be set on this page by just searching in the browser for "timezone_type" https://github.com/php/php-src/blob/ef255c9f0f2c2ad1ea224ed215edb00f5bc205bd/ext/date/php_date.c#L2269 This issue is occurring on PHP 5.6 and later (shown in the test script URL) Test script: --------------- https://3v4l.org/ZhQX9 --- OR --- $test = new DateTime('2018-03-05 00:00:00', new DateTimeZone('UTC')); var_dump($test->timezone); // Notice: Undefined property: DateTime::$timezone get_object_vars($test); var_dump($test->timezone); // string(3) "UTC" Expected result: ---------------- string(3) "UTC" string(3) "UTC" Actual result: -------------- Notice: Undefined property: DateTime::$timezone in /in/BQD1t on line 5 NULL string(3) "UTC" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76057&edit=1
