 Hello Patrick,  How do I do this if I need them to be Date/Time fields as the errors last over several days I also need it to exclude weekends if possible

 Hello,  I am using two Date/Time fields to mark the start and end of a brake in out IT. I want the rules formulae to work out the difference between them as a mean time to repair for reporting currently using an spreadsheet but feel this is more progressive and can then add in other functions off this.
