Import of testsite from T3D exceeds PHP maximum_execution_time
When testing the import of a T3D-based testsite package on my local install, I bumped up against PHP's maximum_execution_time of 30 seconds. Once I raised this limit in php.ini, the import worked properly.
At Michael Stucki's suggestion, I revert to the original php.ini and added "ini_set('max_execution_time', 300);" to the top of typo3conf/localconf.php, which also fixed the timeout problems.
Adding ini_set to the impexp system extension should fix this issue.
