Daily Calendar Display - Mix/Max Time

Daily Calendar Display - Mix/Max Time

I have been working to modify the .js files to solve what seems like a simple problem.

The daily/weekly calendar widget retrieves and displays on-screen from 12:00 midnight to like 12:00 pm.  Since I only work from 6:00 am to 6:00 pm, this causes the 'working day' to be very small.  

I'd like to be able to manipulate the calendar to start the daily view at 6:00 am and end at 6:00 pm.

I've attempted to use the minTime and maxTime variables in fullcalendar.min.js to accomplish this, but it doesn't seem to have any effect.

Also, agenda,js seems to also be one area that could be manipulated.

Any ideas on how to work around this?
