easiest fix is to divide it out and multiply the number of seconds you want by 38 - thats what Im doing in my code, assuming 38 cycles per second

and since we are all tweaking this by observing the machine on the field, and nudging the numbers a little, it doenst really matter if your seconds are lockstep with the National Beuro of Standards in Bolder Colorado

or better yet, forget seconds and work in loop counts - one less thing to worry about.
