Hi again,

After consulting with Android caldav client's author, this is the
information I got from him:


DTSTART;TZID=Europe/Athens:20111117T200000Z
DTEND;TZID=Europe/Athens:20111117T204501Z

That's an ambiguous time zone specification. There is a "Z" which means 
"UTC", but there is a TZID that specifies another time zone too.
That's a bug in Horde.

I guess the event is meant to start at 20:00 CET. In that case these 
line should look like

DTSTART;TZID=Europe/Athens:20111117T200000
DTEND;TZID=Europe/Athens:20111117T204501

Another uncommon thing that sticks out is that the actual time zone 
definition (the VTIMEZONE part) is at the end of the file. I think 
that's correct, but it's very uncommon. Some clients might fail here.

I hope it helps.

Best.
