For example, 6:00pm - 8:00pm, is displayed as 8:00pm - 10:00pm when viewing the calendar (the pop-up bubble and also the click-thru).
(My timezone is GMT+2, which might be relevant to the 2-hour error in the displayed time - as if the timezone offset has been applied twice?)
Single, non-repeating events are correctly displayed.
