korganizer timezone question

I have a problem with a remote saved event, that is read back a collegue. I see the entry in my korganizer from 1500-1600 hours, but my collegue sees them it from 1400-1500 hours. Most of the settings in korganizer related to timezone settings seems similar in his and my korganizer. The remotely saved file has a DTSTART of 1400 (without an Z), which I think is a pointer for the cause of this problem.... Why is the event saved as 1400 and not as 1500 hours? As this is for a common agenda, it may give funny effects (people appearing much to early e.g. ;) -- Richard Bos Without a home the journey is endless
