Hello, I've read my way through the forum, but I still haven't found a solution for my conundrum. Here goes. I receive invites from a person who is located in Central Europe, while I am in the UK, so different time zones. Let's say the invite is for 4pm Central European Summer Time, which would be 3pm British Summer Time. The invite entry ends up at neither time in iCal, but instead at 5pm, which is complete nonsense whichever way one looks at it, and since it is an invite I can neither move the entry nor allocate a different time zone to it.

 

Any ideas of a) what's going wrong here and b) how I can correct it? I don't mind the entries ending up at the sender's time, although ideally I would like to be able to adjust the time zone so that they end up at the time that's correct for me. But having them moved by iCal in the opposite direction makes no sense at all.

 

Any help appreciated, the current state makes iCal pretty useless to me.

Thanks

    Hi,

     

    Is this from only one person?

     

    Do you have iCal's timezone support turned on in Prefernces > Advanced? If so what does it say th etimezone is at the top right of iCal's main window?

     

    Have you looked at the raw text of the invite to confirm their invite has the correct time information?

     

    Best wishes

    The date DTSTART:20120920T171500Z indicates a date at 5.15pm GMT on the 20th September 2012, not CET.  The Z indicates the date is UTC (Universal Time Code) which equates to GMT. Offsetting for BST that would be 6.15pm BST. Therefore the date is being shown correctly in iCal.  For the date to be Central European Time the DTSTART element would reference the timezone (and not end in z).

     

    More than you want to know about the iCalendar standard. Section 4.3.5 refers to the date formats used in iCalendar files.

     

    I suggest you could contact your friend to check their timezone settings, or perhaps Lotus Notes doesn't do timezones...

     

    Best wishes

    I'm not saying the problem is at the other end, just that the date as you posted it was not a CET date.

     

    Do you have a copy of the original invitation email with the attached .ics file?

    Thanks, that makes it clearer.

     

    DTSTART;TZID="W. Europe":20120920T171500

    DTEND;TZID="GMT":20120920T184000

     

    There is one likely main issue here. The event starts in 'W. Europe' and ends in 'GMT'. iCal does not 'do' events starting in one timezone and ending in another.  Many people have pointed this out as a failing in the past. 

     

    This is just a guess, but I would expect iCal's importer is not loading the full data and reading all the offsets as GMT when reading this .ics file. You could report this as a bug to Apple, and/or ask your friend to make his events start & end in the same timezone.

     

    Hope this makes sense.

     

    Best wishes

    Sorry, my mistake. It is reading all the times as 'floating', still not much use.

    I am having a  very similar problem and have noted in other forums that others are also experiencing similar problems. In my case the meeting invite (from Lotus Notes) is sent from London (GDT time) and iCal translates a five hour difference to CDT. It should be six hours. I have read that this happens only when the UK is on GDT and the problem goes away after the daylight savings time switch back to GMT. My guess (thougth not scientific) is that iCal is not translating daylight savings time?
