Description

Returns the number of days (including fractional days) between two specified TDateTime values.

Call DaySpan to obtain the difference, in days, between two TDateTime values. Unlike the DaysBetween function, which only counts whole days, DaySpan reports incomplete days as a fraction of an entire day.

DaySpan always returns a positive result and therefore the parameter values are interchangeable.
