Breaking: #69930 - Remove option "serverTimeZone"

See forge#69930

Description

The option $TYPO3_CONF_VARS['SYS']['serverTimeZone'] which was introduced when there was no clean way to fetch the timezone option in the PHP4 environment, has been removed. It was solved in PHP 5.1.0 which introduced date_default_timezone_get() which is used by the TYPO3 Core by default.

Impact

Accessing the option will result in a PHP notice, as it has been removed in TYPO3 CMS 7. Extensions making use of this option will result in an unexpected behaviour as possible calculations are wrong.

Affected Installations

Any TYPO3 installation which uses a third-party extensions that uses this option.

Migration

Use native timezone support by PHP directly. See date_default_timezone_get() for more information.
