Hello, the evolution calendar has a problem with summertime in following scenario: 1. Evolution is connected with an M$ Exchange Server 2. An outlook user sends a date proposal The message is display with a difference in time of one hour. But if you send a confirmation, the outlook users will get the correct time set in the confirmation mail. The problem is, that the evolution calendar stores the wrong time in the calendar and does not display the correct time. This results in problems to share meeting appointments. But in other case, if you send a date proposal, the time settings are correct. Because I rechecked the problem by using outlook instead of evolution, all appointments seems to be fine. The problem does not occur if the computers operating in winter time. The VCS-file sent by outlook seems to be ok in both cases, therefore I would say the problem is on the evolution side of communication, IMHO. Bye Andreas
