There's a red line in the main calendar window showing the current time of day. But apart from right when a new hour starts, this line does not line up (haha) with the actual time - instead, it lags behind considerably. Shown in the picture is an event that ends at half past one. The screenshot was taken at twenty to two, but the red line is still further up than the event's end, so roughly twenty minutes slow. What's going on?
