lets say you wanted to make a clock,.. this is a good start, a thing you might take a look at.. without calling any internal functions related to the clock, i have a described a clock,.. time as we know it today, i would describe as 3600 beats per time necessary for the sun to cross 15^ across the sky as an "hour",.. the kind of thing you would want to think about before making your own time program. so this a thing that should work for exactly 24 hours and then you should be back at 0.
