I have a set of date ranges for a production line that I need to adjust so that the 48 hours of idle time from Fri 23:00 to Sun 23:00 are added to the end date range.

Basically the week-ends are idle time for the production line so my end date needs to factor in that idle time and reflect the true end time (where a week-end is present in the date range of course).

i.e.

2/2/12 3:59 AM 2/2/12 8:20 AM
2/2/12 8:20 PM 2/3/12 12:41 AM
2/3/12 3:00 PM 2/6/12 10:09 AM


Thanks,
Brad
