bug in the time somewhere?

bug in the time somewhere?

Ok as i write it is 12:50 pm on my computer clock which is correct for where I am (London, UK)
My company settings is gmt london
I have a meeting schedule at 8pm tonight
But in 'Meetings and conferences' it says meeting in about 1 hour and 10 minutes
instead of 7 hours and 10 minutes

Any help please?
