function DaysBetween(const ANow, AThen: TDateTime): Integer;
C++ syntax:
extern PACKAGE int __fastcall DaysBetween(const System::TDateTime ANow, const System::
TDateTime AThen);
Description
Call DaysBetween to obtain the difference, in days, between two TDateTime values.
DaysBetween counts only whole days. Thus, DaysBetween reports the difference between Dec 31, 1999 11:59 PM and Jan 1, 2000 11:58 PM as 0 because the difference is one minute short of an entire day.
