Hi David, the variable would be a treatment like a pain-killer ;) I frighten that the real reason (e.g. summer/winter time) might disappear and then suddenly the time would be wrong again. You might can try http://sogo-demo.inverse.ca/SOGo/dav/sogo1/Calendar/personal/ which is the demo account of the Sogo. For sure, I am more then willing to help with debugging. Just let me know where to look. If you can't use the demo account let me know and I will check if you can get access to our Sogo installation.
