Wrong Time in Invitations - Caldav Problem

When i am inviting people with my caldav calender the invitation some one gets is +1 hour. For example i sent an invitation with 14.00 the invitation says 15.00. It happens since about a week now. i didn’t change any settings. What can I do?

Check internet time automatic synchronization. I’s better to disable it, should work. The issue occurs, mostly, by the way, with the external calendars, like Google, etc.

Thanks, but can you tell me where i can find the option?

Sure. Go to your taskbar. Press the clock icon with the right mouse button and choose date/time settings
