I don't know the iCalendar spec so I don't know what an RRULE is. But
as far as I can see, `icalendar--convert-tz-offset' is used while
converting an ics file to the diary format.

Probably. Looking at the ical spec, this X-WR-TIMEZONE property is an
optional extension nobody has to obey. Org exports the times like
which means "local time". So probably the google server has UTC as
local time, my preferences say I want to use Berlin-time, so all events
get two hours added in summer.
Now I've tried to explicitly set the timezone information using
and now the events are like
However, that doesn't change anything in google calendar...
Finally, I've set GMT+0 as my current timezone in google calendar, and
now my appointments are shown correctly. Ok, that's not really a
solution but only a workaround...
Oh, there's another possibility; setting
which then seems to correctly recalculate the local times in my org
files to GMT. So for an entry that starts at 14:30 and ends an 16:30,
that's what exported.
Looks good, I'd say. But when importing that to google calendar, it
shows that entry starting at 16:30 and ending at 18:30 Berlin-time. Now
Oh, it seems to be some caching issue. Although the new ics file is on
the server now, it seems that a reload of google calendar doesn't
reimport all imported calendars. So I'll wait a bit and report back
what methods work (explicit TZIDs and/or export as UTC).
