I would like to calculate the number of work hours between two dates with the 
basis of a workday being 9:00 to 17:00.  Before reinventing the wheel, I 
wanted to check to see if anyone has already done this before and if there is 
(by some great chance) support for it a base 3.8 image.

Thanks.

the flesh I live by the faith of the Son of God, who loved 
me, and gave himself for me."
