Of course. I was mostly joking. If someone were concerned with subsecond timing, I don't think they'd be doing something that took very long (ie. something that would have to run for a while and that might span midnight). So if they saw that it took -86398 seconds, they would know it was too late and that they should go to bed and try again later.
