>>> Hallo list,
>>>
>>> after the upgrade to Horde Groupware 5.0.1 I'm experiencing  
>>> several problems when I try to accept an invitation and add the  
>>> event to my calendar.
>>>
>>> In case 1 the event is correctly added to my calendar but the  
>>> answer to the person who invented me is not send with the  
>>> following error:
>>>
>>> 2012-11-09T11:44:32+00:00 DEBUG: HORDE [imp] Fehler beim Versenden  
>>> der Antwort: No From: address has been provided [pid 25778 on line  
>>> 27 of  
>>> "/usr/share/php/Horde/Core/Notification/Handler/Decorator/Hordelog.php"]
>>>
>>> This look like I had not configured an address to answer these  
>>> invitations. All of my identities have valid From-Addresses so I'm  
>>> not sure what to do now.
>>
>> Does the event organizer provide an email address in the  
>> invitation? If not, it's completely useless.
>>
>>> In case 2 the event is neither added to the calendar nor the  
>>> answer is sent. The error message below says that there is an  
>>> invalid timezone:
>>>
>>> 2012-11-09T13:06:24+01:00 DEBUG: HORDE [kronolith]  
>>> DateTimeZone::__construct(): Unknown or bad timezone (W. Europe  
>>> Standard Time) [pid 25779 on line 27 of  
>>> "/usr/share/php/Horde/Core/Notification/Handler/Decorator/Hordelog.php"]
>>>
>>> As in case 1 the event is correctly added, is it possible that the  
>>> wrong timezone is provided by the person who invited me and that  
>>> this is not a horde error? I use the follwing line in Horde's  
>>> conf.php:
>>
>> Short answer: yes.
>>
>> Long answer: "W. Europe Standard Time" is not a valid time zone  
>> name, unfortunately iCalendar allows to make up your own time zone  
>> names though and provide the DST rules with the event. We ignore  
>> those rules though, because we simply cannot work with arbitrary  
>> DST rules. No one can, so I doubt *any* client or server on this  
>> world is really using those. That's why *every* sane client uses  
>> Olsen time zone names when sending iCalendar objects. So:  
>> technically that client might be correct, but it's still completely  
>> broken when it comes to common sense. Assuming that it really uses  
>> that name, which I cannot tell for sure unless you provide that  
>> invitation.
