Roll is specifically for cases where you want one of the fields to increase or decrease without affecting the others (e.g. if you had a spin control in your GUI with a DateTime backing it and didn't want any units other than the currently altered unit to change when its value wrapped around). In most cases, you're simply going to want to add a Duration to it - which dt + days(n) or dt + n.days will do. - Jonathan M Davis
