I have a spreadsheet to plan production over a 24 hour period. This
works fine but we are now moving to a 2 shift pattern so there will be
4 hours non productive time every day. The current formula uses simple
arithmetic adding a task duration onto the finish time for the last
task.
I now need to factor in the extra time should a task span the period
of non production.

Thanks
