Time displays only when there is an "end date/time"

Fragment of a discussion from Help talk:Eventcalendar format
The current implemented logic follows [1] and [2]
[2] http://arshaw.com/fullcalendar/docs/event_data/Event_Object/
SRF_EventCalendar.php is perfectly correct. This is an issue with fullcalendar.
The reason for this behavior was because of fullcalendar.min.js (line 4652 in fullcalendar.js):
if (!event.allDay && seg.isStart) { html += ...
This is the js-code for displaying the time in month view. Events without end-time are set to allDay-events. This code only shows the time if it is not an event.allDay. To show the time if there is a start date we can change this to:
if (event.start && seg.isStart) { html += ...
