Hi Kasper,
We installed PHP 5.3.3. and the Factory time zone works for us, so I guess our version is slightly different from yours. However, the documentation states that in future versions of PHP the Factory time zone will not be supported.
We have updated the PHP code generators to use UTC instead. If you download new versions of the codegenerators, your generated code should work. We are looking for a solution where the time zone is configurable, that will work with the coming releases of php aswell as older versions, and that generates backward compatible code.
However, the new code generators should solve the problem for now.
Best regards,
