Note that this clock is in 24-hour time. This clock displays the time in binary form. To read the hours, for example: if the row displays 001011, you read it from right to left, with each cell representing 2^{0}, 2^{1}, ..., 2^{5}, and the 0s and 1s indicate whether you do not need to count them or whether you do, respectively. Therefore 001011 would be 2^{0} (1) + 2^{1} (2) + 2^{3} (8), which is 11, so the hour is 11. It is the same method for calculating the minutes and seconds.
