Does the total editing time in the document information calculate one day as 24 hours or the length of a work day? If it is a work day, does length of a week also count weekends or 5 days? I think it would be clearer if it would show it in hours. Maybe it could be a setting that can be changed to show it in hours or put it in parentheses at the end?

As far as I remember, it just counts hours, and when 24 is reached, it notates it as a day.
