Calendar Event Times not evaluated correctly

If you have a calendar event that starts at 9:30am and ends at say 10 am the next day, the calendar event beginning and end times only show 30 min apart so if you are using this to display calendar information in a ring segment then it will only segment for 30 minutes whereas the event is actually 1 day and 30 minutes long. There is no current solution to fix this aside from adding in event start and end dates.
