Description

Returns the number of seconds between two specified TDateTime values.

Call SecondsBetween to obtain the difference, in seconds, between two TDateTime values. SecondsBetween counts only entire seconds. Thus, SecondsBetween reports the difference between 9:00:00 A.M. and 9:00:00:999 A.M. as 0, because the difference is one millisecond short of an entire second.

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