>From my experience, the DBI ctSchedule and eXontrol controls are geared for tasks that are days long, not hours. I would look at using something like http://www.dbi-tech.com/Product_Page_Solutions_PIM.asp for hourly assignments.

I remember I've once used DBI's scheduler control for a golf course - i.e. in 15-minute slots, IIRC. If we're talking about the same control, that is; if not, then they have one that can do finer than days.
