Abstract: TIME OF DAY CLOCK CONTROL A time of day clock for a computer is run off a clock for the computer processor by selecting the processor clock cycle T such that a binary multiple N of the time of day unit cycle D contains an integral number K of processor cycles T or ND = KT in accordance with the equation: D = ( R + ? ) T, where R is the integer nearest the actual D/T ratio, and X represents the number of time of day cycles D of longer or shorter duration than R processor cycles needed to establish the fractional relationship between the two cycles over the period ND.
