I'm a little puzzled by this. Last night I inputted this event into my calendar via my ipad (ios 6). This morning I got ios8 and I just synced my calendars. As you can see, the event is from 7-10 (which is exactly what I put in), but then it added the 11 PM (GMT) after it. It's weird because when I click on Edit event, it actually lists the event as 11PM-2AM GMT. But from my first screenshot, the actual event appears at 7-10 Eastern Time. Can someone help me to diagnose where the issue is?
