I just noticed that there seems to be some error concerning the time here: Although I set my Timezone to GMT+1 in the profile, the time is still displayed as GMT which means there's always one hour missing...
Edit: I set my timezone to GMT+2 (which is actually not correct as I'm living in germany) and now the time is correct
