I've installed Fullcalendar, it works fine. I have two 'event' types created and displaying in the Fullcalendar. I want to turn off the display of start/end time for certain events. For instance, 'Labor Day' doesn't have a start or end time. How can I do this?

On the module's drupal page at: http://drupal.org/project/fullcalendar
is a sample Fullcalendar that shows some Fullcalendar entries with no time displayed. How is this done?
