Hello guys

I am having a problem that must be simple, but I am not being able to solve it.

I have a time in hh:mm:ss:

mTime = '09:30:00'
mMinu = '00:01:25'

I want to increase the Mminu in Mtime so that it can be:  '09:31:25'

When I do this, my time is increase and not crease the time :(

var
  H : Ttime;
  mTime, mMinu : String;
  mTime := '09:30:00'
  mMinu := '00:01:25'

  H := StrToTime(mTime);
  H := H + StrToTime(mMinu);

Open in new window


Why it is increase my time? What should I do to solve this?

thanks
Alexandre

This code works fine for me
procedure TForm1.Button1Click(Sender: TObject);
var
  H: Ttime;
  mTime, mMinu: String;
begin
  mTime := '09.30.00';
  mMinu := '00.01.25';
  H := StrToTime(mTime)+ StrToTime(mMinu);
  showmessage(timetostr(h));
end;

Open in new window

What kind of problem are you having?

Anyway you could use inCsecond function from DateUtils

Something like
uses DateUtils;
  mTime := '09.30.00';
  H := StrToTime(mTime);
  Showmessage(Timetostr(IncSecond(h,85)));
