If an event lasts more than one day in an event list it does not allow displaying the start time and end time. If it starts on Friday, April 13 at 8:00 p.m. and ends at 5:00 a.m., it does not allow you to show "from 8:00 p.m. to 5:00 a.m." It only allows you to set the start date as April 13 and the closing date as April 14.
