Old events appear in iCal Upcoming events

Events from the past can appear in iCal Upcoming Event when they are set up as "all day events".

How to reproduce:

• create a page with iCal Upcoming events on it and link a calendar

• create a Event which last "all day" -> make sure that this event was yesterday

• go to calendar and refresh then you will see the event from yesterday

• Please note that if you create a "all day" event from Monday to Thursday you will still at Friday with the date from Monday

What I expect:
The Event will not be displayed at the next day

What really happens:
The Event appears as upcoming event even if it is in the past
