datetime to integer

what do you want to compare?
You do not need to convert it to an integer (which isn't even possible, only to float) to compare.

you can adress a tdatetime as a double :) why would you need an integer?

and use them to compare in what way? is it a string or a tdatetime var?if it is a string you can use Strtodatetime

fi

var a:tdatetime;

begin
  a:=Strtodatetime('10/08/2007 10:45');
end;

It's easy: int comparison = dateTimeA.CompareTo(dateTimeB);

I found a function that gives me what I need

  DateTimeToUnix()

and

  UnixToDateTime()

Can you not use the standard

CompareDateTime( dateTime1, dateTime2)

Which will return -1, 0 or +1 depending which is larger or if they are equal.

system.pas defines
TDateTime = type Double;

so you can compare dates using standard operators (=, <, >) or as mike suggested use CompareDateTime (defined in DateUtils.pas).

if you really, really, really need integer use:
datetime_as_int := Round(ADateTime * SecsPerDay)

ziolko.

is this function is OK?

DateTimeToFileDate()
