A similar function to MinuteOfTheYear, the function SecondOfTheYear returns the number of complete seconds between the TDateTime value entered as AValue, and 12:00 A.M. of the first day of the year that includes AValue.
It can be a very large number.
Declaration: Function SecondOfTheYear(const AValue: TDateTime): Cardinal;
A simple example follows.
procedure ScriptEvent (var Value : variant);
var
ThoseSecs : cardinal;
begin
//YESTERDAY is 28-11-2023, so the result is 28598400
ThoseSecs := SecondOfTheYear(Yesterday);
LogInfo('The number of minutes since 1st Jan are '+IntToStr(ThoseSecs));
