calculate maximum time from one column with total minutes, one column with start time
Hello!  I would like to be able to have one column in which the maximum time in minutes is entered and one column in which a starting time is entered.  I would like the maximum time in minutes to be added to the start time to produce a column with what the ending time should be.  For example, Column A, 30 minutes.  Column B, 12:15:00, and Column C (Column A + B = ) 12:45:00.

Please help me!

Thanks so much!
