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.


Thanks 

Totti

It's difficult. I will need to add some (optional) excessive debugging
output for seeing what's happening. Or maybe you could provide an
account on some server running SUGo so that I can debug this myself.

I guess the easy way out would be to add a variable which allows
shifting the time by X hours before sending it to the server. But I'd
rather avoid that kludge.
