WordPress MU

When my users register they get automatical -7 in the timezone setting.

I would like to have +2.

Note that I also have the possibilty to change the php.ini.

It's in wp-admin/upgrade-schema.php. Look for gmt offset option and set it like this:

add_option('gmt_offset', 2);

Sorry for asking more but there is (according to me) only one line that relates to this:

275: add_option('gmt_offset', date('Z') / 3600);

Does this really means that the timezone will be moved to -8?

Thank you qza.

If you don't want to change core files you can use the WPMU new blog settings plugin.
