It's all a little bit complicated and I keep wondering to myself why I don't 
just implement a TimeOfDayRange** to get me past it.  Basically worker time is 
orderable in 15 minute increments with a start time and a duration and I then 
have to break that duration down into the relevant rates.  I was hoping to just 
be able to iterate over each ordered 15 minute intervals and test them against 
each of the 3 temporal expressions (standard, overtime, double time) to 
determine which window each falls within.

I can't seem to understand why DateRange, HourRange and MinuteRange are okay 
but a TimeOfDayRange is a bad design?

** I just noticed the deprecated implementation in 10.04, and it seems to do 
exactly what I had in mind, even if the design/implementation is flawed do you 
think it might work for my situation?

Thanks
Scott
