I just tried it and the detected timezone for me is called:
"Africa/Ceuta (Romance Standard Time) (UTC+01:00) Brussels, Copenhagen, Madrid, Paris"
While the assigned delta with GMT is correct, this is confusing as hell because neither Brussels, Copenhaguen, Madrid or Paris are in Africa. You may want to take a look at the TZ info you are using.
EDIT: See comment below, this is not an issue.
