Timeline - Calculate end date/time with shift/lunch start and end

Rev12,

The first issue would be that the End Date w/o lunch break column is not calculating correctly, given the shift start and end times. If you review the attached, given the inputs on Timeline tab, the end time of 2:30 pm is correct. However, adding another 30 minutes to the op total time rolls the end date to 6/12 7:00 am, as opposed to 6/11 3:00 pm.
