Hi Kevin,

I want to work out a way to add 'working hours' onto a time. I.e. 21/09/2012 12:00 + 4 work hours = 21/09/2012 16:00, 21/09/2012 17:00 + 4 work hours = 24/09/2012 11:00. I also would like to be able to set the start day and end day so the 'working hours' are predefined.

Does that make things clearer?
