For me it is simmilar with an ownCloud CalDAV calendar.
For example, an all-day event on the 12th will be shown on the 11th in Wingpanel Date&Time indicator's month-view AND maya month-view.
But on maya's day-view on the right, the same all-day event will be shown at the correct date.
Non all-day events are shown reversed in maya: when the event is on the 11th, then it's shown in day-view on the 12th.
