The reason it is a day is that date/times are stored as a number of days from a base date using the whole number portion of the number, and the time using the decimal portion.

So quite often, you see adjustments to date/times like this.

=IF(F23<D23, F23+1, F23)-D23

This looks to see if the time in column F is less than the time in column D. If it is, that means the time in column F is actually from yesterday and would result in a negative time span. To account for this, a single day is added to the time in column F which ensures it is after the time in column D.
