Why why why doesn't Apple solve this question definitely ? It doesn't have to do with Summer time safe or time zone management. It has to do with a BUG that Apple doesn't care to solve... In my case, and although Lisbon is in the same time zone as London, it keeps considering Lisbon as Central European Time when in fact is West European Time... So, if i choose Lisbon in Iphone or Ipad and create a new event in my ical in those devices, it keeps considering one hour more in appointments passed to Outlook !!!. However, if i create the event in Outlook it doesn't have any problem!!! So, the solution was to choose London in those devices and now there is no problem. Of course, I can't set the devices to automatically set the location any more... conclusion: Apple doesn't give a sh"" to these problems because they are americans and forget that there is a world outside their borders...
