The time zone was not applied for
the day name, day number and month name in
event invitation emails.
So, if the starting time of the event
was close to the previous/next day
(e.g starting date at 04/09/2015 00:30 in UTC+1)
The day number/name was set to the previous day
(e.g. Wednesday 8th instead of Thursday 9th).
