TDateTime is a float value. The integer part gives the day and the decimal part gives the time. To add 25 minutes then you need to do this:

Label1.Caption := TimeToStr(Now + EncodeTime(0, 25, 0, 0));

You can't just ass 25 straight onto the time as that's not how it works. The above does

Hi systemop,

const
  OneHour = 1/24;
  OneMin = OneHour / 60;
....
TimeToStr(Now+ 25*OneMin)
