Description

Returns the number of seconds (including fractions thereof) between two specified TDateTime values.

Call SecondSpan to obtain the difference, in seconds, between two TDateTime values. Unlike the SecondsBetween function, which only counts entire seconds, SecondSpan reports incomplete seconds as a fraction of an entire second.

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