When you start a timer for, say, 10 seconds, it starts counting down at "9 seconds" and then for the final second it displays "0 seconds". This is because fractions of a second are always rounded down for display.
It would be more intuitive if the timer started at "10 seconds" and displayed "1 second" for the final second. That is, seconds should be rounded up for display.
