Calendar events sent out by Exchange insist on calling the Germany timezone pretty much anything but CET. So far, I have seen Romance, Western Europe Time (which Wikipedia says is wholly different timezone), and now this... The timezone-make-date-arpa-standard function will handle all of the above except your case :( Because of the GMT in the timezone name, the timestamps in your calendar are parsed as GMT, thus the time shift of 1 hour. My idea of solving this would be introducing customizable variable containing mappings from any non-standard TZ identifier to a generally recognized TZ name.
