# elapsed seconds as hours:minutes:seconds

Posted on 2003-11-11

I have an integer variable with a total number of elapsed seconds stored in it. I need to format it as  hours:minutes:seconds

can someone create a function for me which takes an integer of elapsed seconds and returns a string formatted as such : hours:minutes:seconds

Thanks

Shane

Hi Shane,

Are you looking for sth. like this?

procedure TForm1.Button1Click(Sender: TObject);

function ConvertSecondsToTime(iSeconds: Word): TDateTime;
var
hr, min: Word;
begin
hr := trunc(iSeconds / 3600);
iSeconds := iSeconds - (3600 * trunc(iSeconds / 3600));
min := trunc(iSeconds / 60);
iSeconds := iSeconds - (60 * trunc(iSeconds / 60));
Result := encodeTime(hr, min, iSeconds, 0);
end;

begin
ShowMessage(TimeToStr(ConvertSecondsToTime(42343)));
end;

This (nested) function converts seconds to TDateTime format. The date is incorrect, of course, but you're able to extract the time like shown in my example. You can also change Word to LongWord if you want to...

Hi,

this will give you elapsed time as a string, but it needs tidying up...

function GetTimeStr(const TimeInSecs: Integer): string;
var
iHours, iMinutes, iSecs: Integer;
sHours, sMinutes, sSecs: string;
begin
iHours := Floor(TimeInSecs / 3600);
sHours := IntToStr(iHours);
Result := IfThen(iHours > 0, StringOfChar('0', 2 - Length(sHours)) +
sHours, '00') + ':';
iMinutes := Floor((TimeInSecs mod 3600) / 60);
sMinutes := IntToStr(iMinutes);
Result := Result + IfThen(iMinutes > 0,
StringOfChar('0', 2 - Length(sMinutes)) + sMinutes, '00') + ':';
iSecs := Floor((TimeInSecs mod 3600) mod 60);
sSecs := IntToStr(iSecs);
Result := Result + IfThen(iSecs > 0,
StringOfChar('0', 2 - Length(sSecs)) + sSecs, '00');
end;

btw it uses Math and StrUtils units

end;

Hm, that wasn't that difficult to adjust. Anyway, this would be my function:

procedure TForm1.Button1Click(Sender: TObject);

function ConvertSecondsToTime(iSeconds: Word): String;
var
hr, min: Word;
begin
hr := trunc(iSeconds / 3600);
iSeconds := iSeconds - (3600 * trunc(iSeconds / 3600));
min := trunc(iSeconds / 60);
iSeconds := iSeconds - (60 * trunc(iSeconds / 60));
Result := Format('%.2d:%.2d:%.2d', [hr, min, iSeconds]);
end;

begin
ShowMessage(ConvertSecondsToTime(42300));
end;

Regards,
Markus

Wouldn't
Seconds div 3600
be more elegant than
Trunc(Seconds / 3600)
and
Floor(Seconds / 3600)
?

You're right, gary! Using div is much more elegant. Forgot about it :/
