It is the CD's responsibility to officiate the event, competition or not, for the entire time stated on the sanction.
Actually the "Event Sanction Application" only requires a date to be specified not the amount of time or hours. Unless specified elsewhere an event could only be a minute long...I hope you are not trying to say the CD should be there at the opening and locking of the gate on the day of "The Event"... because that would be an erroneous interpretation.
