How to remove the seconds from TTime without resorting to TimeToStr(const datetime:TDateTime; const formatsettings:TFormatSettings)

Question

How can the seconds be removed from a TTime variable without resorting to the extra overhead of using TimeToStr(const datetime:TDateTime; const formatsettings:TFormatSettings) to get the TTime value without the seconds?

ie this is what I need -> HH:MM:00.

Is there some kind of math operation (like ANDing or ORing the value with something) that can be performed?

Answer 1

uses
  ..., DateUtils;

var
  t: TTime;
begin
  t := ...;
  t := RecodeSecond(t, 0);
end;

Answer 2

var
  t: TTime;
  iHour, iMin, iSec, iMSec: Word;

DecodeTime(t, iHour, iMin, iSec, iMSec);
t := EncodeTime(iHour, iMin, 0, 0);
